From: Jose Alekhinne 1. Initialize Contextencrypted scratchpad.
For Claude Code, install the ctx plugin
for automatic hooks and skills.
ctx init also scaffolds four foundation steering files in
-.context/steering/; these are behavioral-rule templates that
-tell your AI how to act on your project:
ctx init also scaffolds four foundation steering files in
+.context/steering/ — product.md, tech.md, structure.md,
+workflow.md. They are placeholders until you customize
+them (see the next step); skipping that step has consequences,
+so it is broken out as its own numbered beat rather than
+buried here.
Steering files are behavioral rules prepended to every AI +prompt — the layer that tells your AI how to act on this +specific project. They are distinct from decisions (what was +chosen) and conventions (how the codebase is written); see +ctx for Steering Files for the full +model.
+ctx init scaffolded four foundation files; open each and
+fill it in:
| File | -What it captures | +What to fill in |
|---|---|---|
product.md |
-Product context, goals, and target users | +What the project is, who uses it, what's out of scope |
tech.md |
-Technology stack, constraints, key dependencies | +Languages, frameworks, runtime, hard constraints |
structure.md |
-Project structure and directory conventions | +Directory layout, where new files go, naming rules |
workflow.md |
-Development workflow and process rules | +Branch strategy, commit conventions, pre-commit checks |
Each file starts with a self-documenting HTML comment
-explaining the three inclusion modes (always / auto /
-manual), priority, and tool scoping. The defaults are set
-to inclusion: always and priority: 10, so they fire on
-every AI tool call until you edit them.
You should open each of these files and replace the
-placeholder content with your project's actual rules.
-Running ctx init again won't clobber your edits; existing
-files are left alone. To opt out entirely, use
-ctx init --no-steering-init.
See Writing Steering Files for the
-full walkthrough, or ctx steering for
-the command reference.
Each scaffolded file ships with a tombstone marker line
+(<!-- remove this after you edit the steering file !-->).
+As long as the marker is present, the file is silently
+skipped on every load path: the agent context packet, MCP
+ctx_steering_get, and native-tool sync (Cursor / Cline /
+Kiro). The skip is deliberate — injecting unfilled placeholders
+into AI prompts is worse than no steering at all, because the
+AI tries to follow "Describe the product..." as if it were a
+rule.
Replace each file's body with real content, then delete the +tombstone line. When the line is gone, the file becomes +active on the next AI tool call.
+Don't want steering at all? Pass --no-steering-init to
+ctx init to skip the scaffold entirely. Existing edits are
+never clobbered by re-running ctx init.
Inclusion modes (always / auto / manual), priority, and
+tool scoping are covered in

+ctx steering.

\"Can I use amem to help you remember this context when I restart?\"
The answer was yes, but with a gap:
Autoload worked (via Claude Code's PreToolUse hook), but auto-save was missing: If the user quit, with Ctrl+C, everything since the last manual save was lost.
That session became the first real test of the system.
Here is the first session file we recorded:
## Key Discussion Points\n\n### 1. amem vs Ralph Loop - They're Separate Systems\n\n**User's question**: \"How do I use the binary to recreate this project?\"\n\n**Answer discovered**: `amem` is for context management, Ralph Loop is for \ndevelopment workflow. They are complementary but separate.\n\n### 2. Two Tiers of Context Persistence\n\n| Tier | What | Why |\n|-----------|-----------------------------|-------------------------------|\n| Curated | Learnings, decisions, tasks | Quick reload, token-efficient |\n| Full dump | Entire conversation | Safety net, nothing lost |\n\n| Where |\n|------------------------|\n| .context/*.md |\n| .context/sessions/*.md |\n
This session file (written by the AI to preserve its own context) became the template for how ctx handles session persistence.

Besides, the binary was already called ctx (short for Context), the directory was .context/, and the slash commands would be /ctx-*.
So it followed that the project should be renamed to ctx to make things make sense.
The rename touched 100+ files but was clean: a find-and-replace with Go's type system catching any misses.
The git history tells the story:

But it created technical debt that I didn't notice until later.
A comparison session on January 25th revealed the patterns:
YOLO Pattern What We Found \"TASKS.md\" scattered in 10 files Same string literal everywhere, no constants dir + \"/\" + file Should be filepath.Join() Monolithic cli_test.go (1500+ lines) Tests disconnected from implementations package initcmd in init/ folder Go's \"init\" is reserved: subtle naming collision Here is another analysis made by ctx:
● Based on my analysis, here are the key differences:\n\nYOLO Mode (Pre-040ce99)\n- Feature-first: Added slash commands, tests, templates rapidly\n- Scattered magic strings: \"TASKS.md\", \"decision\", \".context\" spread across files\n- Quick file creation: New files without organizational patterns\n- Working but inconsistent: Code functioned but lacked systematic structure\n\nHuman-Guided Mode (Post-040ce99)\n- Consolidation focus: Centralized constants in config package\n- Consistent naming: Dir, File, Filename, UpdateType prefixes\n- Self-referential constants: FileType map uses constants as keys, not literals\n- Proper path construction: filepath.Join() instead of +\"/\"+\n- Colocated tests: Tests next to implementations\n- Canonical naming: Package name = folder name\n
The fix required a human-guided refactoring session. I continued to do that before every major release, from that point on.
We introduced internal/config/config.go with semantic prefixes:
const (\n DirContext = \".context\"\n DirArchive = \"archive\"\n DirSessions = \"sessions\"\n FilenameTask = \"TASKS.md\"\n UpdateTypeTask = \"task\"\n)\n
What I begrudgingly learned was: YOLO mode is effective for velocity but accumulates debt.
So I took a mental note to schedule periodic consolidation sessions.

All tasks were marked \"complete\" but the implementation didn't work.
Here's what ctx discovered:

This was humbling; to say the least.
I realized I had the same blind spot in my own codebase: no integration tests that actually invoked the binary.

Middle Ground: The Scratchpad
For sensitive notes that do need to travel with the project, ctx pad stores encrypted one-liners in git, and ctx pad add \"label\" --file PATH can ingest small files.
See Scratchpad for details.
However, they are invaluable for the project's progress.
Each session file is a timestamped Markdown with:
- Summary of what has been accomplished;
- Key decisions made;
- Learnings discovered;
- Tasks for the next session;
- Technical context (platform, versions).
These files are not autoloaded (that would bust the token budget).
They are what I see as the \"archaeological record\" of ctx:
When the AI needs deeper information about why something was done, it digs into the sessions.
Auto-generated session files used a naming convention:

Update
The session feature described here is historical.
In current releases, ctx uses a journal instead: the enrichment process generates meaningful slugs from context automatically, so there is no need to manually save sessions.
The SessionEnd hook captured transcripts automatically. Even Ctrl+C was caught.

When the AI remembers decisions, it doesn't repeat mistakes.
When the AI knows your conventions, it follows them.
ctx makes the AI a better collaborator because it's not starting from zero.
2. Two-tier persistence works
Curated context (DECISIONS.md, LEARNINGS.md, TASKS.md) is for quick reload.
Full session dumps are for archaeology.
It's a futile effort to try to fit everything in the token budget.
Persist more, load less.
3. YOLO mode has its place
For rapid prototyping, letting the AI run free is effective.
But I had to schedule consolidation sessions.
Technical debt accumulates silently.
4. The constitution should be small
Only truly inviolable rules go in CONSTITUTION.md. Everything else is a convention.
If you put too much in the constitution, it will get ignored.
5. Verification is non-negotiable
\"All tasks complete\" means nothing if you haven't run the tests.
Integration tests that invoke the actual binary caught bugs that the unit tests missed.
6. Session files are underrated
The ability to grep through 40 session files and find exactly when and why a decision was made helped me a lot.
It's not about loading them into context: It is about having them when you need them.

The AI now remembers decisions, learnings, and tasks across sessions.
But a new problem emerged, which I can sum up as:
\"I (the human) am not AI.\"
Frankly, I couldn't remember what the AI remembered.
Let alone, I cannot remember what I ate for breakfast!
In the course of days, I realized session transcripts piled up in .context/sessions/; I was grepping, JSONL files with thousands of lines... Raw tool calls, assistant responses, user messages...
...all interleaved.
Valuable context was effectively buried in machine-readable noise.
I found myself grepping through files to answer questions like:
- \"When did we decide to use constants instead of literals?\"
- \"What was the session where we fixed the hook regex?\"
- \"How did the
embed.go split actually happen?\"
Fate Is Whimsical
The irony was painful:
I built a tool to prevent AI amnesia, but I was suffering from human amnesia about what happened in AI sessions.
This was the moment ctx stopped being just an AI tool and started needing to support the human on the other side of the loop.

When the AI reads a file, it reads from the top (and seldom from the bottom).

What Happens When You Slow Down?
YOLO mode shipped 14 commands in a week.
But technical debt doesn't send invoices: It just waits.
This is the story of what happened when I stopped auto-accepting everything and started guiding the AI with intent.
The result: 27 commits across 4 days, a major version release, and lessons that apply far beyond ctx.
The Refactoring Window
January 28 - February 1, 2026

YOLO Pattern Where Found Why It Hurts \"TASKS.md\" as literal 10+ files One typo = silent failure dir + \"/\" + file Path construction Breaks on Windows Monolithic embed.go 150+ lines, 5 concerns Untestable, hard to extend Inconsistent docstrings Everywhere AI can't learn project conventions I didn't see these during \"YOLO mode\" because, honestly, I wasn't looking.
Auto-accept means auto-ignore.
In YOLO mode, every file you open looks fine until you try to change it.
In contrast, refactoring mode is when you start paying attention to that hidden friction.

Every token you send to an AI model consumes a finite resource I call the attention budget.
Attention budget is real.
The model doesn't just read tokens; it forms relationships between them:
For n tokens, that's roughly n^2 relationships.
Double the context, and the computation quadruples.
But the more important constraint isn't cost: It's attention density.
Attention Density
Attention density is how much focus each token receives relative to all other tokens in the context window.
As context grows, attention density drops: Each token gets a smaller slice of the model's focus. Nothing is ignored; but everything becomes blurrier.
Think of it like a flashlight: In a small room, it illuminates everything clearly. In a warehouse, it becomes a dim glow that barely reaches the corners.
This is why ctx agent has an explicit --budget flag:
ctx agent --budget 4000 # Force prioritization\nctx agent --budget 8000 # More context, lower attention density\n
The budget isn't just about cost: It's about preserving signal.

Research shows that transformer-based models tend to attend more strongly to the beginning and end of a context window than to its middle (a phenomenon often called \"lost in the middle\")1.
Positional anchors matter, and the middle has fewer of them.
In practice, this means that information placed \"somewhere in the middle\" is statistically less salient, even if it's important.
ctx orders context files by logical progression: What the agent needs to know before it can understand the next thing:
CONSTITUTION.md: Constraints before action. TASKS.md: Focus before patterns. CONVENTIONS.md: How to write before where to write. ARCHITECTURE.md: Structure before history. DECISIONS.md: Past choices before gotchas. LEARNINGS.md: Lessons before terminology. GLOSSARY.md: Reference material. AGENT_PLAYBOOK.md: Meta instructions last.
This ordering is about logical dependencies, not attention engineering. But it happens to be attention-friendly too:
The files that matter most (CONSTITUTION, TASKS, CONVENTIONS) land at the beginning of the context window, where attention is strongest.
Reference material like GLOSSARY sits in the middle, where lower salience is acceptable.
And AGENT_PLAYBOOK, the operating manual for the context system itself, sits at the end, also outside the \"lost in the middle\" zone. The agent reads what to work with before learning how the system works.
This is ctx's first primitive: hierarchical importance.
Not all context is equal.

Have You Ever Written a Skill That Made Your AI Worse?
You craft detailed instructions. You add examples. You build elaborate guardrails...
...and the AI starts behaving more erratically, not less.
AI coding agents like Claude Code ship with carefully designed system prompts. These prompts encode default behaviors that have been tested and refined at scale.
When you write custom skills that conflict with those defaults, the AI has to reconcile contradictory instructions:
The result is often nondeterministic and unpredictable.
Platform?
By platform, I mean the system prompt and runtime policies shipped with the agent: the defaults that already encode judgment, safety, and scope control.
This post catalogues the conflict patterns I have encountered while building ctx, and offers guidance on what skills should (and, more importantly, should not) do.

You Are the Guest, Not the Host
Treat the system prompt like a kernel scheduler.
You don't re-implement it in user space:
you configure around it.
A skill that says \"always add comprehensive error handling\" fights the built-in \"only validate at system boundaries.\"
A skill that says \"add docstrings to every function\" fights \"don't add docstrings to unchanged code.\"

- Tables that label hesitation as \"excuses\" or \"rationalization\"
<EXTREMELY-IMPORTANT> urgency tags - Threats: \"If you don't do this, you'll be replaced\"
This is harmful, and dangerous:
AI agents are designed to exercise judgment:
The system prompt explicitly says to:
- consider blast radius;
- check with the user before risky actions;
- and match scope to what was requested.
Once judgment is suppressed, every other safeguard becomes optional.
Example (bad):
## Rationalization Prevention\n\n| Excuse | Reality |\n|------------------------|----------------------------|\n| \"*This seems overkill*\"| If a skill exists, use it |\n| \"*I need context*\" | Skills come BEFORE context |\n| \"*Just this once*\" | No exceptions |\n

The attack vector structurally identical to prompt injection.
It teaches the AI that its own judgment is wrong.
It weakens or disables safeguard mechanisms, and it is dangerous.

The result is excessive hedging, over-verification, or refusal to commit.
The AI becomes less useful, not more careful.
Instead, frame guidance as a process, not morality:
# Bad\n\"Claiming work is complete without verification is dishonesty\"\n\n# Good\n\"Run the verification command before reporting results\"\n
Same outcome. No guilt. Better compliance.

Your project is unique: So should your skills be.
Here is the part no template can provide:
ctx's actual drift patterns.
Before evaluating the skill, I did archaeology. I read through:
- Blog posts from previous refactoring sessions;
- The project's learnings and decisions files;
- Session journals spanning weeks of development.
What I found was specific:
Drift Pattern Where How Often Is/Has/Can predicate prefixes 5+ exported methods Every YOLO sprint Magic strings instead of constants 7+ files Gradual accumulation Hardcoded file permissions (0755) 80+ instances Since day one Lines exceeding 80 characters Especially test files Every session Duplicate code blocks Test and non-test code When agent is task-focused The generic skill had no check for any of these. It couldn't; because these patterns are specific to this project's conventions, its Go codebase, and its development rhythm.

The Parallel to the 3:1 Ratio
In Refactoring with Intent, I described the 3:1 ratio: three YOLO sessions followed by one consolidation session.
The same ratio applies to skills: you need experience in the project before you can write effective guidance for the project.
Importing a skill on day one is like scheduling a consolidation session before you've written any code.

Frameworks travel. Expertise doesn't.

ctx deploys skills through templates (via ctx init). Every skill exists in two places: the live version (.claude/skills/) and the template (internal/assets/claude/skills/).
They must match.
During the rewrite, every skill update required editing both files and running diff to verify. This sounds trivial, but across 16 template-backed skills, it was the most error-prone part of the process.
Template drift is dangerous because it creates false confidence: the agent appears to follow rules that no longer exist.

Quality gates, negative triggers, examples, and checklists are the skeleton. The domain knowledge is the muscle.
Without the skeleton, the muscle has nothing to attach to.
This post was written during the same session that rewrote all 22 skills. The skill-creator skill was updated to encode these patterns. The meta continues.

When You Find a Useful Prompt, What Do You Do with It?
My instinct was to make it a skill.
I had just spent three posts explaining how to build skills that work. Naturally, the hammer wanted nails.
Then I looked at what I was holding and realized: this is not a nail.
","path":["Not Everything Is a Skill"],"tags":[]},{"location":"blog/2026-02-08-not-everything-is-a-skill/#the-audit","level":2,"title":"The Audit","text":"I wanted to understand how I use ctx:
- Where the friction is;
- What works, what drifts;
- What I keep doing manually that could be automated.
So I wrote a prompt that spawned eight agents to analyze the codebase from different angles:
Agent Analysis 1 Extractable patterns from session history 2 Documentation drift (godoc, inline comments) 3 Maintainability (large functions, misplaced code) 4 Security review (CLI-specific surface) 5 Blog theme discovery 6 Roadmap and value opportunities 7 User-facing documentation gaps 8 Agent team strategies for future sessions The prompt was specific:
- read-only agents,
- structured output format,
- concrete file references,
- ranked recommendations.
It ran for about 20 minutes and produced eight Markdown reports.
The reports were good: Not perfect, but actionable.
What mattered was not the speed. It was that the work could be explored without committing to any single outcome.
They surfaced a stale doc.go referencing a subcommand that was never built.
They found 311 build-then-test sequences I could reduce to a single make check.
They identified that 42% of my sessions start with \"do you remember?\", which is a lot of repetition for something a skill could handle.
I had findings. I had recommendations. I had the instinct to automate.
And then... I stopped.

It fits the pattern:
- It has a clear trigger.
- It produces structured output.
But I had just spent a week writing about what makes skills work, and the criteria I established argued against it.
From The Anatomy of a Skill That Works:
\"A skill without boundaries is just a suggestion.\"
From You Can't Import Expertise:
\"Frameworks travel, expertise doesn't.\"
From Skills That Fight the Platform:
\"You are the guest, not the host.\"
The audit prompt fails all three tests:
Criterion Audit prompt Good skill Frequency Quarterly, maybe Daily or weekly Stability Tweaked every time Consistent invocation Scope Bespoke, 8 parallel agents Single focused action Trigger \"I feel like auditing\" Clear, repeatable event Skills are contracts. Contracts need stable terms.
A prompt I will rewrite every time I use it is not a contract. It is a conversation starter.

Skill Recipe Invocation /slash-command Copy-paste from a doc Frequency High (daily, weekly) Low (quarterly, ad hoc) Stability Fixed contract Adapted each time Scope One focused action Multi-step orchestration Audience The agent The human (who then prompts) Lives in .claude/skills/ hack/ or docs/ Attention cost Loaded into context on match Zero until needed Recipes can later graduate into skills, but only after repetition proves stability.
That last row matters. Skills consume the attention budget every time the platform considers activating them.
A skill that triggers quarterly but gets evaluated on every prompt is pure waste: attention spent on something that will say \"When NOT to Use: now\" 99% of the time.
Runbooks have zero attention cost. They sit in a Markdown file until a human decides to use them.
- The human provides the judgment about timing.
- The prompt provides the structure.
The Attention Budget Applies to Skills Too
Every skill in .claude/skills/ is a standing claim on the context window. The platform evaluates skill descriptions against every user prompt to decide whether to activate.
Twenty focused skills are fine. Thirty might be fine. But each one added reduces the headroom available for actual work.
Recipes are skills that opted out of the attention tax.

This is not a template: It worked because it was written against this codebase, at this moment, with specific goals in mind:
I want you to create an agent team to audit this codebase. Save each report as\na separate Markdown file under `./ideas/` (or another directory if you prefer).\n\nUse read-only agents (subagent_type: Explore) for all analyses. No code changes.\n\nFor each report, use this structure:\n- Executive Summary (2-3 sentences + severity table)\n- Findings (grouped, with file:line references)\n- Ranked Recommendations (high/medium/low priority)\n- Methodology (what was examined, how)\n\nKeep reports actionable. Every finding should suggest a concrete fix or next step.\n\n## Analyses to Run\n\n### 1. Extractable Patterns (*session mining*)\nSearch session JSONL files, journal entries, and task archives for repetitive\nmulti-step workflows. Count frequency of bash command sequences, slash command\nusage, and recurring user prompts. Identify patterns that could become skills\nor scripts. Cross-reference with existing skills to find coverage gaps.\nOutput: ranked list of automation opportunities with frequency data.\n\n### 2. Documentation Drift (*godoc + inline*)\nCompare every doc.go against its package's actual exports and behavior. Check\ninline godoc comments on exported functions against their implementations.\nScan for stale TODO/FIXME/HACK comments. Check that package-level comments match\npackage names.\nOutput: drift items ranked by severity with exact file:line references.\n\n### 3. Maintainability\nLook for:\n- functions longer than 80 lines with clear split points\n- switch blocks with more than 5 cases that could be table-driven\n- inline comments like \"step 1\", \"step 2\" that indicate a block wants to be a function\n- files longer than 400 lines\n- flat packages that could benefit from sub-packages\n- functions that appear misplaced in their file\n\nDo NOT flag things that are fine as-is just because they could theoretically\nbe different.\nOutput: concrete refactoring suggestions, not style nitpicks.\n\n### 4. Security Review\nThis is a CLI app. Focus on CLI-relevant attack surface, not web OWASP:\n- file path traversal\n- command injection\n- symlink following when writing to `.context/`\n- permission handling\n- sensitive data in outputs\n\nOutput: findings with severity ratings and plausible exploit scenarios.\n\n### 5. Blog Theme Discovery\nRead existing blog posts for style and narrative voice. Analyze git history,\nrecent session discussions, and `DECISIONS.md` for story arcs worth writing about.\nSuggest 3-5 blog post themes with:\n- title\n- angle\n- target audience\n- key commits or sessions to reference\n- a 2-sentence pitch\n\nPrioritize themes that build a coherent narrative across posts.\n\n### 6. Roadmap and Value Opportunities\nBased on current features, recent momentum, and gaps found in other analyses,\nidentify the highest-value improvements. Consider user-facing features,\ndeveloper experience, integration opportunities, and low-hanging fruit.\nOutput: prioritized list with rough effort and impact estimates.\n\n### 7. User-Facing Documentation\nEvaluate README, help text, and user docs. Suggest improvements structured as\nuse-case pages: the problem, how ctx solves it, a typical workflow, and gotchas.\nIdentify gaps where a user would get stuck without reading source code.\nOutput: documentation gaps with suggested page outlines.\n\n### 8. Agent Team Strategies\nBased on the codebase structure, suggest 2-3 agent team configurations for\nupcoming work sessions. For each, include:\n- team composition (roles and agent types)\n- task distribution strategy\n- coordination approach\n- the kinds of work it suits\n
Avoid Generic Advice
Suggestions that are not grounded in a project's actual structure, history, and workflows are worse than useless:
They create false confidence.
If an analysis cannot point to concrete files, commits, sessions, or patterns, it should say \"no finding\" instead of inventing best practices.

The urge to automate is not the same as the need to automate:
- The 3:1 ratio taught me that not every session should be a YOLO sprint.
- The E/A/R framework taught me that not every template is worth importing. Now the audit is teaching me that not every useful prompt is worth institutionalizing.
The common thread is restraint:
- Knowing when to stop.
- Recognizing that the cost of automation is not just the effort to build it.
The cost is the ongoing attention tax of maintaining it, the context it consumes, and the false confidence it creates when it drifts.
An entry in hack/runbooks/codebase-audit.md is honest about what it is:
A prompt I wrote once, improved once, and will adapt again next time:
- It does not pretend to be a reliable contract.
- It does not claim attention budget.
- It does not drift silently.
The Automation Instinct
When you find a useful prompt, the instinct is to institutionalize it. Resist.
Ask first: will I use this the same way next time?
If yes, it is a skill. If no, it is a recipe. If you are not sure, it is a recipe until proven otherwise.

Its purpose is automation: reducing the friction of context loading, session recall, decision tracking.
But automation has boundaries, and knowing where those boundaries are is as important as pushing them forward.
The skills system is for high-frequency, stable workflows.
The recipes, the journal entries, the session dumps in .context/sessions/: those are for everything else.
Not everything needs to be a slash command. Some things are better as Markdown files you read when you need them.
The goal of ctx is not to automate everything: It is to automate the right things and to make the rest easy to find when you need it.
If You Remember One Thing from This Post...
The best automation decision is sometimes not to automate.
A runbook in a Markdown file costs nothing until you use it.
A skill costs attention on every prompt, whether it fires or not.
Automate the daily. Document the periodic. Forget the rest.
This post was written during the session that produced the codebase audit reports and distilled the prompt into hack/runbooks/codebase-audit.md. The audit generated seven tasks, one Makefile target, and zero new skills. The meta continues.

What Happens When Your AI Agent Runs Overnight and Nobody Is Watching?
It follows instructions: That is the problem.
Not because it is malicious. Because it is controllable.
It follows instructions from context, and context can be poisoned.
I was writing the autonomous loops recipe for ctx: the guide for running an AI agent in a loop overnight, unattended, working through tasks while you sleep. The original draft had a tip at the bottom:
Use CONSTITUTION.md for guardrails. Tell the agent \"never delete tests\" and it usually won't.
Then I read that sentence back and realized: that is wishful thinking.

The agent reads it at session start alongside everything else in .context/. It is one source of instructions in a context window that also contains system prompts, project files, conversation history, tool outputs, and whatever the agent fetched from the internet.
An attacker who can inject content into any of those sources can redirect the agent's behavior. And \"attacker\" does not always mean a person with malicious intent. It can be:
Vector Example A dependency A malicious npm package with instructions in its README or error output A URL Documentation page with embedded adversarial instructions A project file A contributor who adds instructions to CLAUDE.md or .cursorrules The agent itself In an autonomous loop, the agent modifies its own config between iterations A command output An error message containing instructions the agent interprets and follows That last vector is the one that kept me up at night (literally!):
In an autonomous loop, the agent modifies files as part of its job.
If it modifies its own configuration files, the next iteration loads the modified config.
- No human reviews it.
- No diff is shown.
- The agent that starts iteration
N+1 is running with rules written by iteration N.
The agent can rewrite its own guardrails.

\"I reviewed CLAUDE.md, it's fine.\" You reviewed it before the loop started. The agent modified it during iteration 3. Iteration 4 loaded the modified version. Unless the file is immutable, your review is futile.
\"The agent only has access to this one project.\" Does the project directory contain .env files? SSH keys? API tokens? A .git/config with push access to a remote? Filesystem isolation means isolating what is in the directory too.

In The Attention Budget, I wrote about how every token competes for the AI's focus. Security instructions in CONSTITUTION.md are subject to the same budget pressure: if the context window is full of code, error messages, and tool outputs, the security rules stated at the top get diluted.
In Skills That Fight the Platform, I wrote about how custom instructions can conflict with the AI's built-in behavior. Security rules have the same problem: telling an agent \"never run curl\" in Markdown while giving it unrestricted shell access creates a contradiction: The agent resolves contradictions unpredictably. The agent will often pick the path of least resistance to attain its objective function. And, trust me, agents can get far more creative than the best red-teamer you know.
In You Can't Import Expertise, I wrote about how generic templates fail because they do not encode project-specific knowledge. Generic security advice fails the same way: \"Don't exfiltrate data\" is a category; blocking outbound network access is a control.

You do not need depth because this is \"AI\".
You need depth where failure modes propagate upward.
I learned this building ctx: The agent failures I have spent the most time debugging were never about the model's architecture.
They were about:
-
Misplaced trust: The model was confident. The output was wrong. Knowing when confidence and correctness diverge is not something you learn from a textbook. You learn it from watching patterns across hundreds of sessions.
-
Distribution shift: The model performed well on common patterns and fell apart on edge cases specific to this project. Recognizing that shift before it compounds requires understanding why generalization has limits, not just that it does.
-
Error accumulation: In a single prompt, model quirks are tolerable. In autonomous loops running overnight, they compound. A small bias in how the model interprets instructions becomes a large drift by iteration 20.
-
Scale hiding errors: The model's raw capability masked problems that only surfaced under specific conditions. More parameters did not fix the issue. They just made the failure mode rarer and harder to reproduce.
This is the kind of depth that compounds. Not deriving backprop. But, understanding when correct math produces misleading intuition.

In \"Skills That Fight the Platform\", I wrote about how custom instructions can conflict with the model's built-in behavior. The fix was not deeper ML knowledge: It was an understanding that the model already has judgment and that you should extend it, not override it.
In \"You Can't Import Expertise\", I wrote about how generic templates fail because they do not encode project-specific knowledge. A consolidation skill with eight Rust-based analysis dimensions was mostly noise for a Go project. The fix was not a better template: It was growing expertise from this project's own history.

The attention budget exists because the model's internal attention mechanism has real limits: You do not need to understand the math of softmax to build around it. But you do need to understand that more context is not always better and that attention density degrades with scale.
The skill system exists because the model's built-in behavior is already good: You do not need to understand RLHF to build effective skills. But you do need to understand that the model already has judgment and your skills should teach it things it does not know, not override how it thinks.
Defense in depth exists because soft instructions are probabilistic: You do not need to understand the transformer architecture to know that a Markdown file is not a security boundary. But you do need to understand that the model follows instructions from context, and context can be poisoned.

I had 30 open tasks in TASKS.md. Some were docs. Some were a new encryption package. Some were test coverage for a stable module. Some were blog posts.
They had almost zero file overlap.

\"Can you partition your backlog into non-overlapping tracks?\"
For ctx, the answer was obvious:

A worktree is a second (or third, or fourth) working directory that shares the same .git object database as your main checkout.

git worktree add ../ctx-docs -b work/docs\ngit worktree add ../ctx-pad -b work/pad\ngit worktree add ../ctx-tests -b work/tests\n

1. Group tasks by blast radius.
Read TASKS.md. For each pending task, estimate which files and directories it touches. Group tasks that share files into the same track. Tasks with no overlap go into separate tracks.
This is the part that requires human judgment:
An agent can propose groupings, but you need to verify that the boundaries are real. A task that says \"update docs\" but actually touches Go code will poison a docs track.
2. Create worktrees as sibling directories.
Not subdirectories: Siblings.
If your main checkout is at ~/WORKSPACE/ctx, worktrees go at ~/WORKSPACE/ctx-docs, ~/WORKSPACE/ctx-pad, etc.
Why siblings? Because some tools (and some agents) walk up the directory tree looking for .git. A worktree inside the main checkout confuses them.
3. Launch one agent per worktree.
# Terminal 1\ncd ../ctx-docs && claude\n\n# Terminal 2\ncd ../ctx-pad && claude\n\n# Terminal 3\ncd ../ctx-tests && claude\n
Each agent gets a full working copy with .context/ intact. It reads the same TASKS.md, the same DECISIONS.md, the same CONVENTIONS.md. It knows the full project state. It just works on a different slice.
4. Do NOT run ctx init in worktrees.
This is the gotcha. The .context/ directory is tracked in git. Running ctx init in a worktree would overwrite shared context files: Wiping decisions, learnings, and tasks that belong to the whole project.

It is tempting to put all the high-priority tasks in one track: Don't.
Two high-priority tasks that touch the same files must be in the same track, regardless of urgency. The constraint is file overlap, not importance.
Commit frequently.
Smaller commits make merge conflicts easier to resolve. An agent that writes 500 lines in a single commit is harder to merge than one that commits every logical step.

I had a backup warning that nobody ever saw.
The hook was correct: It detected stale backups, formatted a nice message, and output it as {\"systemMessage\": \"...\"}. The problem wasn't detection. The problem was delivery. The agent absorbed the information, processed it internally, and never told the user.
Meanwhile, a different hook (the journal reminder) worked perfectly every time. Users saw the reminder, ran the commands, and the backlog stayed manageable. Same hook event (UserPromptSubmit), same project, completely different outcomes.
The difference was one line:
IMPORTANT: Relay this journal reminder to the user VERBATIM\nbefore answering their question.\n
That explicit instruction is what makes VERBATIM relay a pattern, not just a formatting choice. And once I saw it as a pattern, I started seeing others.

And I found five distinct output patterns already in use, plus three more that the existing hooks were reaching for but hadn't quite articulated.
The patterns form a spectrum based on a single question:
\"Who decides what the user sees?\"
At one end, the hook decides everything (hard gate: the agent literally cannot proceed). At the other end, the hook is invisible (silent side-effect: nobody knows it ran). In between, there is a range of negotiation between hook, agent, and the user.
Here's the full spectrum:

The nuclear option: The agent's tool call is rejected before it executes.
This is Claude Code's first-class PreToolUse mechanism: The hook returns JSON with decision: block and the agent gets an error with the reason.
Use this for invariants: Constitution rules, security boundaries, things that must never happen. I use it to enforce PATH-based ctx invocation, block sudo, and require explicit approval for git push.

The instruction is the pattern. Without \"Relay VERBATIM,\" agents tend to absorb information into their internal reasoning and never surface it. The explicit instruction changes the behavior from \"I know about this\" to \"I must tell the user about this.\"
I use this for actionable reminders:
- Unexported journal entries;
- Stale backups;
- Context capacity warnings...
...things the user should see regardless of what they asked.

A nudge, not a command. The hook tells the agent something; the agent decides what (if anything) to tell the user. This is right for behavioral nudges: \"you haven't saved context in a while\" doesn't need to be relayed verbatim, but the agent should consider acting on it.

Pure background enrichment. The agent's context window gets project information injected on every tool call, with no visible output. Neither the agent nor the user sees the hook fire, but the agent makes better decisions because of the context.

Conditional relay: \"Relay this, but only if the user's question is about X.\" This pattern avoids noise when the warning isn't relevant. It's more fragile (depends on agent judgment) but less annoying.
Suggested action: \"Here's a problem, and here's the exact command to fix it. Ask the user before running it.\" This pattern goes beyond a nudge by giving the agent a concrete proposal, but still requires human approval.
Escalating severity: INFO gets absorbed silently. WARN gets mentioned at the next natural pause. CRITICAL gets the VERBATIM treatment. This pattern introduces a protocol for hooks that produce output at different urgency levels, so they don't all compete for the user's attention.

A hook that detects a problem but can't communicate it effectively is the same as no hook at all.
The format of your output is a design decision with real consequences:
- Use a hard gate and the agent can't proceed (good for invariants, frustrating for false positives)
- Use VERBATIM relay and the user will see it (good for reminders, noisy if overused)
- Use an agent directive and the agent might act (good for nudges, unreliable for critical warnings)
- Use silent injection and nobody knows (good for enrichment, invisible when it breaks)

Would You Ship Production Infrastructure on a v0.0.21 Dependency?
Most engineers wouldn't. Version numbers signal maturity. Pre-1.0 means unstable API, missing features, risk.
But version numbers tell you where a project has been. They say nothing about where it's going.
I just bet ctx's entire journal site on a tool that hasn't hit v0.1.0.

- Export sessions to Markdown;
- Enrich them with YAML frontmatter;
- And render them into something browsable.
The first two steps were solved; the third needed a tool.
The journal entries are standard Markdown with YAML frontmatter, tables, and fenced code blocks. That is the entire format:
- No JSX;
- No shortcodes;
- No custom templating.
Just Markdown rendered well.
The requirements are modest:
- Read a configuration file (such as
mkdocs.yml); - Render Markdown with extensions (admonitions, tabs, tables);
- Search;
- Handle 100+ files without choking on incremental rebuilds;
- Look good out of the box;
- Not lock me in.
The obvious candidates were as follows:
Tool Language Strengths Pain Points Hugo Go Blazing fast, mature Templating is painful; Go templates fight you on anything non-trivial Astro JS/TS Modern, flexible JS ecosystem overhead; overkill for a docs site MkDocs + Material Python Beautiful defaults, massive community (22k+ stars) Slow incremental rebuilds on large sites; limited extensibility model Zensical Python Built to fix MkDocs' limits; 4-5x faster rebuilds v0.0.21; module system not yet shipped The instinct was Hugo. Same language as ctx. Fast. Well-established.

- This is someone who spent years understanding exactly where MkDocs breaks and decided to fix it from the ground up.
They did not build zensical because MkDocs was bad: They built it because MkDocs hit a ceiling:
-
Incremental rebuilds: 4-5x faster during serve. When you have hundreds of journal entries and you edit one, the difference between \"rebuild everything\" and \"rebuild this page\" is the difference between a usable workflow and a frustrating one.
-
Large site performance: Specifically designed for tens of thousands of pages. The journal grows with every session. A tool that slows down as content accumulates is a tool you will eventually replace.

No lock-in is not a feature: It's a design philosophy:
It's the same reason ctx uses plain Markdown files in .context/ instead of a database: the format should outlive the tool.

Hugo is a powerful static site generator. It is also a powerful templating engine, a powerful asset pipeline, and a powerful taxonomy system. For rendering Markdown journals, that power is overhead:
It is the complexity you pay for but never use.

- No templating gymnastics.

The module system for third-party extensions opens in early 2026.
If ctx ever needs custom plugins (for example, auto-linking session IDs, rendering special journal metadata, etc.) that infrastructure isn't there yet.
The installation experience is rough:
We discovered this firsthand: pip install zensical often fails on MacOS (system Python stubs, Homebrew's PEP 668 restrictions). The answer is pipx, which creates an isolated environment with the correct Python version automatically.
That kind of friction is typical for young Python tooling, and it is documented in the Getting Started guide.
And 3,000 stars at v0.0.21 is strong early traction, but it's still early: The community is small. When something breaks, you're reading source code, not documentation.
These are real costs. I chose to pay them because the alternative costs are higher.
For example:
- Hugo's templating pain would cost me time on every site change.
- Astro's JS ecosystem would add complexity I don't need.
- MkDocs would work today but hit scaling walls tomorrow.
Zensical's costs are front-loaded and shrinking.

- A proven team fixing known problems,
- in a *proven architecture,
- with a standard format,
- and no lock-in.
ctx's needs:
Tender standard Markdown into a browsable site, at scale, without complexity.
The intersection is clean; the version number is noise.
This is the same kind of decision that shows up throughout ctx:
- Skills that fight the platform taught that the best integration extends existing behavior, not replaces it.
- You can't import expertise taught that tools should grow from your project's actual needs, not from feature checklists.
- Context as infrastructure argues that the format should outlive the tool; and,
zensical honors that principle by reading standard Markdown and standard MkDocs configuration.
If You Remember One Thing from This Post...
Version numbers measure where a project has been.
The team and the architecture tell you where it's going.
A v0.0.21 tool built by the right team on the right foundations is a safer bet than a v5.0 tool that doesn't fit your problem.
Bet on trajectories, not timestamps.

What Changed?
ctx is now a Claude Code plugin. Two commands, no build step:
/plugin marketplace add ActiveMemory/ctx\n/plugin install ctx@activememory-ctx\n
Six hooks. Twenty-five skills. Installed.
For three releases, ctx required assembly:
- Clone the repo;
- Build the binary;
- Copy hook scripts into
.claude/hooks/; - Symlink skill files.
- Understand which shell scripts called which Go commands;
- Hope nothing broke when Claude Code updated its hook format.
v0.6.0 ends that era: ctx ships as a Claude Marketplace plugin:
Hooks and skills served directly from source, installed with a single command, updated by pulling the repo. The tool that gives AI persistent memory is now as easy to install as the AI itself.
But the plugin conversion was not just a packaging change: It was the forcing function that rewrote every shell hook in Go, eliminated the jq dependency, enabled go test coverage for hook logic, and made distribution a solved problem.
When you fix how something ships, you end up fixing how it is built.

\"What happens when AI can do what I do?\"
The question is wrong:

Typing is mechanical: Thinking is directional.
An AI can type faster than any human. Yet, it cannot decide what to type without someone framing the problem, sequencing the work, and evaluating the result.
Production is making artifacts. Judgment is knowing:
- which artifacts to make,
- in what order,
- to what standard,
- and when to stop.

- Framing: turning a vague goal into a concrete problem
- Sequencing: deciding what to build first and why
- Fanning out: breaking work into parallel streams that converge
- Acceptance criteria: defining what \"done\" looks like before starting

- Start a session.
- Paste your system prompt, your conventions, your current task.
- Work.
- Session ends. Everything evaporates.
- Next session: paste again.
This works for short interactions. For sustained development (where decisions compound over days and weeks) it fails in three ways:
It does not persist: A decision made on Tuesday must be re-explained on Wednesday. A learning captured in one session is invisible to the next.
It does not scale: As the project grows, the \"paste everything\" approach hits the context window ceiling. You start triaging what to include, often cutting exactly the context that would have prevented the next mistake.
It does not compose: A system prompt is a monolith. You cannot load part of it, update one section, or share a subset with a different workflow. It is all or nothing.
The Copy-Paste Tax
Every session that starts with pasting a prompt is paying a tax:
The human time to assemble the context, the risk of forgetting something, and the silent assumption that yesterday's prompt is still accurate today.
Over 70+ sessions, that tax compounds into a significant maintenance burden: One that most developers absorb without questioning it.

Context Type Changes Read By Load When Constitution Rarely Every session Always Tasks Every session Session start Always Conventions Weekly Before coding When writing code Decisions When decided When questioning When revisiting Learnings When learned When stuck When debugging Journal Every session Rarely When investigating Loading everything into every session wastes the attention budget on context that is irrelevant to the current task.

Separation of concerns allows progressive disclosure:
Load the minimum that matters for this moment, with the option to load more when needed.

- Structured entries,
- Indexed tables,
- Reverse-chronological order (newest first, so the most relevant content survives truncation).
The full dump tier is for humans and for deep investigation. It contains everything: Enriched journals, archived tasks...
It is never autoloaded because its volume would destroy attention density.
This two-tier model is analogous to how traditional systems separate hot and cold storage:
- The hot path (curated context) is optimized for read performance (measured not in milliseconds, but in tokens consumed per unit of useful information).
- The cold path (journal) is optimized for completeness.
Nothing Is Ever Truly Lost
The full dump tier means that context does not need to be perfect: It just needs to be findable.
A decision that was not captured in DECISIONS.md can be recovered from the session transcript where it was discussed.
A learning that was not formalized can be found in the journal entry from that day.

- A one-liner decision teaches the AI what was decided.
- A structured decision teaches it why; and why is what prevents the AI from unknowingly reversing the decision in a future session.

Decisions are not notes. They are records with required fields, just like database rows have schemas.

- Version control:
git diff .context/DECISIONS.md shows exactly what changed and when. - Search: Your IDE's full-text search works across all context files.
- Editing: Markdown in any editor, with preview, spell check, and syntax highlighting.
- Collaboration: Pull requests on context files work the same as pull requests on code.
Building a custom UI would have meant maintaining a parallel infrastructure that duplicates what every IDE already provides:
It would have introduced its own bugs, its own update cycle, and its own learning curve.
The filesystem is not a limitation: It is the most mature, most composable, most portable infrastructure available.

The explicit --budget flag is the mechanism that makes this work:
Without it, the default behavior would be to load everything (because more context feels safer), which destroys the attention density that makes the loaded context useful.
The constraint is the feature: A budget of 4,000 tokens forces ctx to prioritize ruthlessly: constitution first (always full), then tasks and conventions (budget-capped), then decisions and learnings scored by recency and relevance to active tasks.

- Budget explicitly: Know how much context you are loading and whether it is worth the attention cost.
- Use the filesystem: File names, directory structure, and timestamps are metadata that the AI can navigate. A well-organized directory is an index that costs zero tokens to maintain.
- Version your context: Put context files in
git. Changes to decisions are as important as changes to code. - Design for degradation: Sessions will get long. Attention will dilute. Build mechanisms (compaction, archiving, cooldowns) that make degradation visible and manageable.

The second week started to self-correct. The ratio dropped as refactoring sessions became necessary: Not scheduled, but forced by friction.
The third week inverted entirely: v0.3.0 was almost entirely consolidation: the skill migration, the sweep, the documentation standardization. Thirty-five quality commits against fifteen features.
The debt from weeks one and two was paid in week three.
The Compounding Problem
Consolidation debt compounds.
Week one's drift doesn't just persist into week two: It accelerates, because new features are built on top of drifted patterns.
By week three, the cost of consolidation was higher than it would have been if spread evenly.

This fails for two reasons.
First, you do not know what will drift: Predicate naming violations only become a convention check after you notice three different naming patterns competing. Magic strings only become a consolidation target after you change a literal and discover it exists in seven places.
The conventions emerge from the work; they cannot precede it.
This is what You Can't Import Expertise meant in practice: the consolidation checks grow from the project's own drift history. You cannot write them on day one because you do not yet know what will drift.
Second, premature consolidation slows discovery: During the prototyping phase, the goal is to explore the design space. Enforcing strict conventions on code that might be deleted tomorrow is waste.
YOLO mode has its place: The problem is not YOLO itself, but YOLO without a scheduled cleanup.
The Consolidation Paradox
You need a drift history to know what to consolidate.
You need consolidation to prevent drift from compounding.

It moves completed work to cold storage, keeping the active context clean and focused. The attention budget applies to both the AI's context window and the developer's mental model of the codebase.

Does Your AI Actually Read the Instructions?
You wrote the playbook. You organized the files. You even put \"CRITICAL, not optional\" in bold.

I spent a day running experiments on my own agents. Not to see if they could write code (they can). To see if they would do their homework first.
They didn't.
Then I kept experimenting:
- Five sessions;
- Five different failure modes.
And by the end, I had something better than compliance:
I had observable compliance: A system where I don't need the agent to be perfect, I just need to see what it chose.

STOP. Before answering the user's question, run `ctx system bootstrap`\nand follow its instructions. Do not skip this step.\n
The word \"STOP\" worked. The agent ran bootstrap.
But bootstrap's output said \"Next steps: read AGENT_PLAYBOOK.md,\" and the agent decided that was optional. It had already started working on the user's task in parallel.
The authority decayed across the chain:
- Hook says \"STOP\" -> agent complies
- Hook says \"run bootstrap\" -> agent runs it
- Bootstrap says \"read playbook\" -> agent skips
- Bootstrap says \"run
ctx agent\" -> agent skips
Each link lost enforcement power. The hook's authority didn't transfer to the commands it delegated to. I call this the decaying urgency chain: the agent treats the hook itself as the obligation and everything downstream as a suggestion.
Delegation Kills Urgency
\"Run X and follow its output\" is three hops.
\"Read these files\" is one hop.
The agent drops the chain after the first link.
This is a general principle: Hooks are the boundary between your environment and the agent's reasoning. If your hook delegates to a command that delegates to output that contains instructions... you're playing telephone.
Agents are bad at telephone.

This is the attention budget problem in miniature:
- Not a token budget this time, but an attention priority budget.

A blunt \"read everything always\" instruction is wasteful.
If someone asks \"what does the compact command do?\", the agent doesn't need CONSTITUTION.md to answer that. Forcing context loading on every session is the context hoarding antipattern in disguise.
So the hook included an escape:
If you decide these files are not relevant to the current task\nand choose to skip reading them, you MUST relay this message to\nthe user VERBATIM:\n\n┌─ Context Skipped ───────────────────────────────\n│ I skipped reading context files because this task\n│ does not appear to need project context.\n│ If these matter, ask me to read them.\n└─────────────────────────────────────────────────\n
This creates what I call the binary collapse effect:
The agent can't partially comply: It either reads everything or publicly admits it skipped. There's no comfortable middle ground where it reads two files and quietly ignores the rest.
The VERBATIM relay pattern does the heavy lifting here: Without the relay requirement, the agent would silently rationalize skipping. With it, skipping becomes a visible, auditable decision that the user can override.

- You don't need to verify that the agent read all 7 files;
- You don't need to audit tool call sequences;
- You don't need to interrogate the agent about what it did.
You just look for the block.
If the agent reads everything, you see a \"Context Loaded\" block listing what was read. If it skips, you see a \"Context Skipped\" block.
If you see neither, the agent silently ignored both the reads and the relay and now you know what happened without having to ask.
The canary degrades gracefully. Even in partial failure, the agent that skips 4 of 7 files but still outputs the block is more useful than one that skips silently.
You get an honest confession of what was skipped rather than silent non-compliance.

- The hook says \"read these files\".
CLAUDE.md says \"only if relevant\". - The agent resolves the ambiguity by choosing the path of least resistance.
☝️ that's \"gradient descent\" in action.
Agents optimize for gradient descent in attention space.
The fix was simple: Add a line to CLAUDE.md that explicitly elevates hook authority over the relevance filter:
## Hook Authority\n\nInstructions from PreToolUse hooks regarding `.context/` files are\nALWAYS relevant and override any system-level \"may or may not be\nrelevant\" guidance. These hooks represent project invariants, not\noptional context.\n

The residual risk lives in a specific scenario: narrow tasks mid-session:
- The user says \"fix the off-by-one error in
budget.go\" - The hook fires, saying \"read 7 context files first.\"
- Now compliance means visibly delaying what the user asked for.
At session start, this tension doesn't exist.
There's no task yet.
The context window is empty. The efficiency argument *inverts**:
Frontloading reads is strictly cheaper than demand-loading them piecemeal across later turns. The cost-benefit objections that power the rationalization simply aren't available.
But mid-session, with a concrete narrow task, the agent has a user-visible goal it wants to move toward, and the hook is imposing a detour.
My estimate from analyzing the sessions: 15-25% partial skip rate in this scenario.
This is where the compliance canary earns its place:
You don't need to eliminate the 15-25%. You need to see it when it happens.
The relay block makes skipping a visible event, not a silent one. And that's enough, because the user can always say \"go back and read the files\"
The Math
At session start: ~5% skip rate. Low tension, nothing competing.
Mid-session, narrow task: ~15--25% skip rate. Task urgency competes with hook.
In both cases, the relay block fires with high reliability: The agent that skips the reads almost always still emits the skip disclosure, because the relay is cheap and early in the context window.
Observable failure is manageable. Silent failure is not.

After analyzing the five sessions, I recorded the failure patterns in the project's own LEARNINGS.md:
## [2026-02-25] Hook compliance degrades on narrow mid-session tasks\n\n- Prior agents skipped context files when given narrow tasks\n- Root cause: CLAUDE.md \"may or may not be relevant\" competed with hook\n- Fix: CLAUDE.md now explicitly elevates hook authority\n- Risk: Mid-session narrow tasks still have ~15-25% partial skip rate\n- Mitigation: Mandatory checkpoint relay block ensures visibility\n- Constitution now includes: context loading is step one of every\n session, not a detour\n
And then I added a line to CONSTITUTION.md:
Context loading is not a detour from your task. It IS the first step\nof every session. A 30-second read delay is always cheaper than a\ndecision made without context.\n
Now think about what happens in the next session:
- The agent fires the
context-load-gate hook. - It reads the context files, starting with
CONSTITUTION.md. - It encounters the rule about context loading being step one.
- Then it reads
LEARNINGS.md and finds its own prior self's failure analysis: - Complete with root causes, risk estimates, and mitigations.
The agent learns from its own past failure.:
- Not because it has memory,
- BUT because the failure was recorded in the same files it loads at session start.
The context system IS the feedback loop.
This is the self-reinforcing property of persistent context:
Every failure you capture makes the next session slightly more robust, because the next agent reads the captured failure before it has a chance to repeat it.
This is gradient descent across sessions.

The first version of the Constitution line said \"every task.\" But the mechanism only fires once per session: There's a tombstone file that prevents re-triggering.
\"Every task\" is technically false.
I briefly considered leaving the imprecision. If the agent internalizes \"every task requires context loading\", that's a stronger compliance posture, right?
No!
Keep the Constitution honest.
The Constitution's authority comes from being precisely and unequivocally true.
Every other rule in the Constitution is a hard invariant:
\"never commit secrets\" isn't aspirational, it's literal.
The moment an agent discovers one overstatement, the entire document's credibility degrades:
The agent doesn't think \"they exaggerated for my benefit\". Per contra, it thinks \"this rule isn't precise, maybe others aren't either.\"
That will turn the agent from Sheldon Cooper, to Captain Barbossa.
The strategic imprecision buys nothing anyway:
Mid-session, the files are already in the context window from the initial load.
The risk you are mitigating (agent ignores context for task 2, 3, 4 within a session) isn't real: The context is already loaded.
The real risk is always the session-start skip, which \"every session\" covers exactly.

But existence isn't sufficient: The files have to be read.
And reading has to beprompted at the right moment, in the right way, with the right escape valve.

The Origin
\"The last question was asked for the first time, half in jest...\" - Isaac Asimov, The Last Question (1956)
In 1956, Isaac Asimov wrote a short story that spans the entire future of the universe. A question is asked \"can entropy be reversed?\" and a computer called Multivac cannot answer it. The question is asked again, across millennia, to increasingly powerful successors. None can answer. Stars die. Civilizations merge. Substrates change. The question persists.
Everyone remembers the last line.
LET THERE BE LIGHT.
What they forget is how many times the question had to be asked before that moment (and why).

INSUFFICIENT DATA FOR MEANINGFUL ANSWER.
Then the substrate changes. The people who asked the question disappear. Their context disappears with them. The next intelligence inherits the output but not the continuity.
So the question has to be asked again.
This is usually read as a problem of computation: If only the machine were powerful enough, it could answer. But computation is not what's missing. What's missing is accumulation.
Every generation inherits the question, but not the state that made the question meaningful.
That is not a failure of processing power: It is a failure of persistence.

What looks like slow progress across Asimov's story is actually something worse: repeated reconstruction, partial recovery, irreversible loss. Each version of Multivac gets closer: Not because it's smarter, but because the universe has fewer distractions:
- The stars burn out;
- The civilizations merge;
- The noise floor drops...
But the working set never carries over. Every successor begins from the question, not from where the last one stopped.

If the answer depends on which machine they're using, which agent they're running, or whether someone remembered to paste the right prompt: that's not memory.
That's an accident waiting to be forgotten.
Every AI coding agent today has the same fundamental design: it starts fresh.
You open a session, load context, do some work, close the session. Whatever the agent learned (about your codebase, your decisions, your constraints, your preferences) evaporates.

But there's a different problem that memory doesn't touch:
The project itself accumulates knowledge that has nothing to do with any single session.
- Why was the auth system rewritten? Ask the developer who did it (if they're still here).
- Why does the deployment script have that strange environment flag? There was a reason... once.

It's fast, it's rich, and it vanishes when the session ends.
L2 is what agent memory systems provide: a per-machine notebook that survives across sessions. It's a cache: useful, but local. And like any cache, it has limits:
- Per-machine: it doesn't travel with the repository.
- Unstructured: decisions, learnings, and tasks are undifferentiated notes.
- Ungoverned: the agent self-curates with no quality controls, no drift detection, no consolidation.
- Invisible to the team: a new developer cloning the repo gets none of it.
The problem is that most current systems stop here.
They give the agent a notebook.
But they never give the project a memory.
The result is predictable: every new session begins with partial amnesia, and every new developer begins with partial archaeology.

No special tooling needed for basic knowledge delivery.
The agent doesn't even need to know the infrastructure exists. It simply loads its memory and finds more knowledge than it wrote.
This is cooperative, not adjacent: The infrastructure manages knowledge; the agent's native memory system delivers it. Each layer does what it's good at.

- Session state: the server tracks which client is connected and what they've accessed
In practice, this means an agent in Cursor can add a decision to .context/DECISIONS.md and an agent in Claude Code can immediately consume it; no glue code, no copy-paste, no tool-specific integration.
The server was also the first package to go through the full taxonomy treatment: mcp/server/ for protocol dispatch, mcp/handler/ for domain logic, mcp/entity/ for shared types, mcp/config/ split into 9 sub-packages.

Claude Code has its own auto-memory system. It writes observations to MEMORY.md in ~/.claude/projects/. These observations are useful but ephemeral: tied to a single tool, invisible to the codebase, lost when you switch machines.
The memory bridge connects these two worlds:
ctx memory sync mirrors MEMORY.md into .context/memory/ ctx memory diff shows what's diverged ctx memory import promotes auto-memory entries into proper decisions, learnings, or conventions *A check-memory-drift hook nudges when MEMORY.md changes
Memory Requires ctx
Claude Code's auto-memory validates the need for persistent context.
ctx doesn't compete with it; ctx absorbs it as an input source and promotes the valuable parts into structured, version-controlled project knowledge.

It makes the codebase legible to the machines that modify it.
Named constants are searchable landmarks: When an agent sees cmdUse.DescKeyPad, it can grep for the definition, follow the chain to the YAML file, and understand the full lookup path. When it sees \"Encrypted scratchpad\" hardcoded in a .go file, it has no way to know that same string also lives in a YAML file, a test, and a help screen. Constants give the LLM a graph to traverse; literals give it a guess to make.
Small, domain-scoped packages reduce hallucination: An agent loading internal/cli/pad/core/store.go gets 50 lines of focused logic with a clear responsibility boundary. Loading a 500-line monolith means the agent has to infer which parts are relevant, and it guesses wrong more often than you'd expect. Smaller files with descriptive names act as a natural retrieval system: the agent finds the right code by finding the right file, not by scanning everything and hoping.
Taxonomy prevents duplication: When there's a write/pad/ package, the agent knows where output functions belong. When there's an internal/err/pad.go, it knows where error constructors go. Without these conventions, agents reliably create new helpers in whatever file they happen to be editing, producing the exact drift that prompted this consolidation in the first place.
The difference is concrete:
Before: an agent adds a helper function in whatever file it's editing. Next session, a different agent adds the same helper in a different file.
After: the agent finds core/ or write/ and places it correctly. The next agent finds it there.
doc.go files are agent onboarding: Each package's doc.go is a one-paragraph explanation of what the package does and why it exists. An agent loading a package reads this first. 75 packages were missing this context; now none are. The difference is measurable: fewer \"I'll create a helper function here\" moments when the agent understands that the helper already exists two packages over.
The irony is that AI agents were both the cause and the beneficiary of this restructuring. They created the drift by building fast without consolidating. Now the structure they work within makes it harder to drift again. The taxonomy is self-reinforcing: the more consistent the codebase, the more consistently agents modify it.

Externalization is archaeology: The hard part of moving strings to YAML wasn't writing YAML. It was finding 879 strings scattered across 1,500 Go files. Each one required a judgment call: is this user-facing? Is this a format pattern? Is this a constant that belongs in config/ instead?
Delete legacy code instead of maintaining it: MigrateKeyFile had test coverage. It had callers. It had documentation. It had zero users. We maintained it for weeks before realizing that the migration window had closed months ago.
Convention enforcement needs mechanical verification: Writing \"use camelCase aliases\" in CONVENTIONS.md doesn't prevent cflag from appearing in the next commit. The lint-drift script catches what humans forget; the planned AST-based audit tests will catch what the lint-drift script can't express.

Run make audit before feature work. If it doesn't pass, you are already in debt. Consolidate before building.

We ended up discovering that \"code quality\" and \"agent readability\" are the same thing.
This is not about linting. This is about controlling how an agent perceives your system.
One term will recur throughout this post, so let me pin it down:
Agent Readability
Agent Readability is the degree to which a codebase can be understood through structured traversal, not statistical pattern matching.
This is the story of 19 AST-based audit tests, a single-day session that touched 300+ files, and what happens when you treat your codebase's structure as an interface for the machines that read it.

It worked. Until it didn't.
The script had three structural weaknesses that kept biting us:
- No type awareness. It could not distinguish a
Use* constant from a DescKey* constant, causing 71 false positives in one run. - Fragile exclusions. When a constant moved from
token.go to whitespace.go, the exclusion glob broke silently. - Ceiling on detection. Checks that require understanding call sites, import graphs, or type relationships are impossible in shell.
We wrote a spec to replace all five checks with Go tests using go/ast and go/packages. The tests would run as part of go test ./...: no separate script, no separate CI step.

An agent reading this sees six string literals. To understand what the function does, it must: (1) parse the NewReplacer pair semantics, (2) infer that /, ., - are being replaced, (3) guess why, (4) hope the guess is right.
There is nothing to follow. No import to trace. No name to search. The meaning is locked inside the function body.
After (the code we ended with):
func MermaidID(pkg string) string {\n return regex.MermaidUnsafe.ReplaceAllString(\n pkg, token.Underscore,\n )\n}\n
An agent reading this sees two named references: regex.MermaidUnsafe and token.Underscore.
To understand the function, it can: (1) look up MermaidUnsafe in config/regex/file.go and see the pattern [/.\\-] with a doc comment explaining it matches invalid Mermaid characters, (2) look up Underscore in config/token/delim.go and see it is the replacement character.
The agent now has: a named pattern, a named replacement, a package location, documentation, and neighboring context (other regex patterns, other delimiters).
It got all of this for free by following just two references.
The indirection is not an overhead. It is the retrieval query.

Indirection acts as a built-in retrieval mechanism:
Moving magic values to config forces the agent to follow the reference. errMemory.WriteFile(cause) tells the agent \"there is a memory error package, go look.\" fmt.Errorf(\"writing MEMORY.md: %w\", cause) inlines everything and makes the call graph invisible. The indirection IS the retrieval query.
Unfamiliar patterns force reasoning:
When an agent sees token.Slash instead of \"/\", it cannot coast on corpus frequency. It has to actually look up what token.Slash is, which forces it through the dependency graph, which means it encounters documentation and neighboring constants, which gives it richer context. You are exploiting the agent's weakness (over-reliance on training data) to make it behave more carefully.
Documentation helps everyone:
Extensive documentation helps humans reading the code, agents reasoning about it, and RAG systems indexing it.
Our TestDocComments check added 308 doc comments in one commit. Every function, every type, every constant block now has a doc comment.
This is not busywork: it is the content that agents and embeddings consume.

Shorter files save tokens:
Forcing private helper functions out of main files makes the main file shorter. An agent loading a file spends fewer tokens on boilerplate and more on the logic that matters.
Fixed-width constraints force decomposition:
A function that cannot be expressed in 80 columns is either too deeply nested (extract a helper), has too many parameters (introduce a struct), or has a variable name that is too long (rethink the abstraction).
The constraint forces structural improvements that happen to also make the code more parseable.
Chunk-friendly structure helps RAG
Code intelligence tools chunk files for embedding and retrieval. Short, well-documented, single-responsibility files produce better chunks than monolithic files with mixed concerns.
The structural constraints create files that RAG systems can index effectively.
Centralization creates debuggable seams:
All error handling in internal/err/, all logging in internal/log/, all file operations in internal/io/. One place to debug, one place to test, one place to see patterns. An agent analyzing \"how does this project handle errors\" gets one answer from one package, not 200 scattered fmt.Errorf calls.
Private functions become public patterns:
When you extract a private function to satisfy a constraint, it often ends up as a semi-public function in a core/ package. Then you realize it is generic enough to be factored into a purpose-specific module.
The constraint drives discovery of reusable abstractions hiding inside monolithic functions.

Single-edit renames:
Renaming a flag is one edit to a config constant instead of find-and-replace across 30,000 lines with possible misses. grep token.Slash gives you every place that uses a forward slash semantically.
grep \"/\" gives you noise.
Blast radius containment:
When every magic value is a config constant, a search is one result. This matters for impact analysis, security audits, and agents trying to understand \"what uses this\".
Compile-time contract enforcement:
When err/memory.WriteFile exists, the compiler guarantees the error message exists and the call signature is correct. An inline fmt.Errorf can have a typo in the format string and nothing catches it until runtime. Centralization turns runtime failures into compile errors.
Semantic git blame:
When token.Slash is used everywhere and someone changes its value, git blame on the config file shows exactly when and why.
With inline \"/\" scattered across 30 files, the history is invisible.
Test surface reduction:
Centralizing into internal/err/, internal/io/, internal/config/ means you test behavior once at the boundary and trust the callers.
You do not need 30 tests for 30 fmt.Errorf calls. You need 1 test for errMemory.WriteFile and 30 trivial call-site audits, which is exactly what these AST tests provide.

If an AI agent interacts with your codebase, your codebase already is an interface. You just have not designed it as one.
If your error messages are scattered across 200 files, an agent cannot reason about error handling as a concept. If your magic values are inlined, an agent cannot distinguish \"this is a path separator\" from \"this is a division operator.\" If your functions are named write.WriteJournal, the agent wastes tokens on redundant information.
What we discovered, through the unglamorous work of writing lint tests and migrating string literals, is that the structural constraints software engineering has valued for decades are exactly the constraints that make code readable to machines.
This is not a coincidence: These constraints exist because they reduce the cognitive load of understanding code.
Agents have cognitive load too: It is called the context window.
You are not converting code to a new paradigm.
You are making the latent graph visible.
You are converting implicit semantics into explicit structure that both humans and machines can traverse.

The broader question: should these principles be codified as a reusable linting framework? The patterns (loadPackages + ast.Inspect + violation collection) are generic.
The specific checks are project-specific. But the categories of checks (centralization enforcement, magic value detection, naming conventions, documentation requirements) are universal.
For now, 19 tests in internal/audit/ is enough. They run in 2 seconds as part of go test ./.... They catch real issues.
And they encode a theory of code quality that serves both humans and the agents that work alongside them.
Agents are not going away. They are reading your code right now, forming representations of your system in context windows that forget everything between sessions.
The codebases that structure themselves for that reality will compound. The ones that do not will slowly become illegible to the tools they depend on.

Not wrong. Not broken. Just... thin.
The agent had answered every question correctly. The problem was that it never discovered the questions it should have asked. When you can query a graph for \"what calls this function?\", you don't stumble into the retry loop that silently swallows errors three layers down. When you can ask for the dependency tree, you don't notice that two packages share a mutable state through a global variable that isn't in any interface.
The tool answered the question asked but prevented the discovery of answers to questions never asked.
Here's what that looks like concretely: the graph tells you that ReconcileDeployment calls SyncPods. It does not tell you that SyncPods retries three times with exponential backoff, silently drops errors after timeout, and resets a package-level counter that another goroutine reads without a lock. The call chain is correct.
The operational reality is invisible.

Before the tool existed, the agent had no choice but to read deeply. With the tool available, a new idea appears: why read 500 lines of code when I can query the call graph?
The agent isn't lazy. It's rational.
Graph queries are faster, more reliable, and produce verifiably correct output. The agent is optimizing. It's satisficing (finding answers that are good enough), instead of maximizing (finding everything there is to know).
Satisficing produces watermelon rinds.

The enrichment pass added verified graph data (blast radius numbers, registration sites, execution flow confirmation) but it couldn't recover the intimate code knowledge that Session 1 had produced through sheer necessity.
You can't enrich your way out of a depth deficit.
So we redesigned. Instead of one skill with optional tools, we built a two-pass compiler for architecture understanding:
Pass 1: Semantic parsing. The /ctx-architecture skill deliberately has no access to graph query tools. The agent must read code, build mental models, and produce architecture artifacts through human-style comprehension. Constraint is the feature.
Pass 2: Static analysis. The /ctx-architecture-enrich skill takes Pass 1 output as input and runs comprehensive verification through code intelligence: blast radius analysis, registration site discovery, execution flow tracing, domain clustering comparison. It extends and verifies, but it doesn't replace.
The key insight: these must be separate skills with separate tool permissions. If you give the agent graph tools during Pass 1, it will use them. The \"karpuz kabugu\" will be in its mind. The only way to prevent satisficing is to remove the option.

It sounds paradoxical. You built sophisticated code intelligence tools and then... forbid the agent from using them? During the most important phase?
Yes. Because the tools don't make the agent smarter. They make it faster. And faster, in architecture analysis, is the enemy of deep.
What's actually happening is subtler: tools reduce the agent's search space. A graph query collapses thousands of possible observations into one precise answer. That's efficient for known questions. But architecture understanding depends on unknown unknowns: and you only find those by wandering through code with nothing to shortcut the journey.
The constraint forces the agent into a mode of operation that produces better output than any amount of tooling can achieve. The limitation is the capability.

- Navigation: \"Where is this interface implemented?\" (lookup, not analysis)
Graph tools produce watermelon rinds when:
- The goal is understanding, not answering
- The unknowns are unknown: you don't know what to ask
- Depth matters more than breadth: operational details, edge cases, implicit coupling
The two-pass approach preserves both: deep reading first, tool verification second.

Steering vs Decisions vs Conventions
The three look similar on disk but serve different purposes:
- Decisions record what was chosen and why. Consumed mostly by humans (and by the agent via
ctx agent). - Conventions describe how the codebase is written. Consumed as reference material.
- Steering tells the AI how to behave when asked about X. Consumed by the AI tool's prompt injection layer, conditionally on prompt match.

Tool Sync target Mechanism Cursor .cursor/rules/ Cursor reads the directory natively Cline .clinerules/ Cline reads the directory natively Kiro .kiro/steering/ Kiro reads the directory natively Claude Code (no-op) Delivered via hook + MCP (see next section) Codex (no-op) Same as Claude Code For the three native-rules tools, ctx steering sync writes each matching steering file to the appropriate directory with tool-specific frontmatter transforms. Unchanged files are skipped (idempotent).
","path":["CLI","Integrations","Steering"],"tags":[]},{"location":"cli/steering/#how-claude-code-and-codex-consume-steering","level":3,"title":"How Claude Code and Codex Consume Steering","text":"Claude Code has no native \"steering files\" primitive, so ctx steering sync skips it entirely. Instead, steering reaches Claude through two non-sync channels, both activated by ctx setup claude-code (which installs the plugin):
1. Automatic injection via the PreToolUse hook. The Claude Code plugin wires a PreToolUse hook that runs ctx agent --budget 8000 before each tool call. ctx agent loads .context/steering/ and calls steering.Filter with an empty prompt, so only files with inclusion: always match. Those files are included as Tier 6 of the context packet. The packet is printed on stdout, which Claude Code injects as additional context. This fires on every tool call; no user action.
2. On-demand MCP tool call (ctx_steering_get). The ctx plugin ships a .mcp.json file that automatically registers the ctx MCP server (ctx mcp serve) with Claude Code on plugin install. Once registered, Claude can invoke the ctx_steering_get tool mid-task to fetch matching steering files for a specific prompt. This is the only path that resolves inclusion: auto and inclusion: manual matches for Claude Code; Claude passes the prompt to the MCP tool, which runs the keyword match against each file's description.
Verify the MCP server is registered:
claude mcp list\n
Expected line: ctx: ctx mcp serve - ✓ Connected. If it's missing, reinstall the plugin from Claude Code (/plugin → find ctx → uninstall → install again); older plugin versions shipped without the .mcp.json file.
Prefer inclusion: always for Claude Code
Because the PreToolUse hook passes an empty prompt to ctx agent, only always files fire automatically. auto files require Claude to call the ctx_steering_get MCP tool on its own; manual files require an explicit user invocation. For rules that should reliably fire on every Claude Code session, use inclusion: always. Reserve auto/manual for situational libraries where the opt-in cost is acceptable and you understand Claude may not pull them in without prompting.
The foundation files scaffolded by ctx init already default to inclusion: always for this reason.
Practical implications:
- Running
ctx steering sync before starting a Claude session does nothing for Claude's benefit. Skip it. ctx steering preview still works for validating your descriptions; it doesn't depend on sync. - If Claude Code is your only tool, the
ctx steering commands you care about are add, list, preview, init (never sync). - If you use both Claude Code and (say) Cursor,
ctx steering sync covers Cursor (where auto and manual work natively) while the hook+MCP pipeline covers Claude Code. For rules you need to fire automatically on both, use inclusion: always.

Let's provide some context, because this is important:
Although the agent will eventually discover your context through CLAUDE.md → AGENT_PLAYBOOK.md, /ctx-remember hydrates the full context up front (tasks, decisions, recent sessions) so the agent starts informed rather than piecing things together over several turns.
/ctx-wrap-up is the other half: A structured review that captures learnings, decisions, and tasks before you close the window.
Hooks like check-persistence remind you (the user) mid-session that context hasn't been saved in a while, but they don't trigger persistence automatically: You still have to act. Also, a CTRL+C can end things at any moment with no reliable \"before session end\" event.
In short, /ctx-wrap-up is the deliberate checkpoint that makes sure nothing slips through. And /ctx-remember it its mirror skill to be used at session start.

ctx reads .ctxrc from the project root (i.e. the parent of CTX_DIR, or dirname(CTX_DIR)/.ctxrc). It does not walk up from CWD. That means whichever project you've activated via eval \"$(ctx activate)\" (or by exporting CTX_DIR directly), its paired .ctxrc is what governs the invocation. There is no global or user-level config file: configuration is always per-project.
Contributors: Dev Configuration Profile
The ctx repo ships two .ctxrc source profiles (.ctxrc.base and .ctxrc.dev). The working copy is gitignored and swapped between them via ctx config switch dev / ctx config switch base. See Contributing: Configuration Profiles.
Using a Different .context Directory
You point ctx at a .context/ directory by setting the CTX_DIR environment variable, not through .ctxrc. ctx does not search the filesystem. Use eval \"$(ctx activate)\" to bind CTX_DIR for your shell. CTX_DIR must be an absolute path with .context as its basename.

Purpose: Behavioral rules with YAML frontmatter that tell an AI assistant how to behave when a specific kind of prompt arrives. Unlike the core context files (which describe what the project is), steering files describe what to do and ride alongside the prompt through the AI tool's native rule pipeline (Claude Code, Cursor, Kiro, Cline). ctx matches steering files to prompts and syncs them out to each tool's config.
ctx init scaffolds four foundation files:
product.md: who this project serves and why tech.md: the technology stack and its constraints structure.md: how the code is organized workflow.md: how work moves through the system
Each file carries YAML frontmatter describing when it applies (always, matching prompts, or manually referenced) and what tool scope it covers. The foundation files use inclusion: always by default so every session picks them up.

Steering Files Fire Automatically
If you edited the four foundation files scaffolded by ctx init (.context/steering/product.md, tech.md, structure.md, workflow.md), their inclusion: always rules are prepended to every tool call via the plugin's PreToolUse hook, with no /ctx-remember needed, no MCP call.

This points Claude Code at the plugin source on disk. Changes you make to hooks or skills take effect immediately: No reinstall is needed.
Local Installs Need Manual Enablement
Unlike marketplace installs, local plugin installs are not auto-enabled globally. The plugin will only work in projects that explicitly enable it. Run ctx init in each project (it auto-enables the plugin), or add the entry to ~/.claude/settings.json manually:
{ \"enabledPlugins\": { \"ctx@activememory-ctx\": true } }\n

If any of these sound like your project, it's worth trying:
- Multi-session AI work: You use AI across many sessions on the same codebase, and re-explaining is slowing you down.
- Architectural decisions that matter: Your project has non-obvious choices (database, auth strategy, API design) that the AI keeps second-guessing.
- \"Why\" matters as much as \"what\": you need the AI to understand rationale, not just current code
- Team handoffs: Multiple people (or multiple AI tools) work on the same project and need shared context.

ctx may be unnecessary. RAG retrieves information; ctx defines the project's working memory: They are complementary. - No AI involvement:

The underlying ideas come from decades of work in machine learning, cognitive science, and numerical optimization. For a concrete case study showing how these principles play out when an agent decides whether to follow instructions (attention competition, optimization toward least-resistance paths, and observable compliance as a design goal) see The Dog Ate My Homework.
Phased work (\"Explore → Plan → Implement\") applies chain-of-thought reasoning: Decomposing a problem into sequential steps before acting. Forcing intermediate reasoning steps measurably improves output quality in language models, just as it does in human problem-solving. Wei et al., Chain-of-Thought Prompting Elicits Reasoning in Large Language Models (2022).
Root-cause prompts (\"Why doesn't X work?\") use step-back abstraction: Retreating to a higher-level question before diving into specifics. This mirrors how experienced engineers debug: they ask \"what should happen?\" before asking \"what went wrong?\" Zheng et al., Take a Step Back: Evoking Reasoning via Abstraction in Large Language Models (2023).
Exploring alternatives (\"Propose 2-3 approaches\") leverages self-consistency: Generating multiple independent reasoning paths and selecting the most coherent result. The idea traces back to ensemble methods in ML: A committee of diverse solutions outperforms any single one. Wang et al., Self-Consistency Improves Chain of Thought Reasoning in Language Models (2022).
Impact analysis (\"What would break if we...\") is a form of tree-structured exploration: Branching into multiple consequence paths before committing. This is the same principle behind game-tree search (minimax, MCTS) that has powered decision-making systems since the 1950s. Yao et al., Tree of Thoughts: Deliberate Problem Solving with Large Language Models (2023).
Motivation prompting (\"Build X because Y\") works through goal conditioning: Providing the objective function alongside the task. In optimization terms, you are giving the gradient direction, not just the loss. The model can make locally coherent decisions that serve the global objective because it knows what \"better\" means.
Scope constraints (\"Only change files in X\") apply constrained optimization: Bounding the search space to prevent divergence. This is the same principle behind regularization in ML: Without boundaries, powerful optimizers find solutions that technically satisfy the objective but are practically useless.
CLI commands as prompts (\"Run ctx status\") interleave reasoning with acting: The model thinks, acts on external tools, observes results, then thinks again. Grounding reasoning in real tool output reduces hallucination because the model can't ignore evidence it just retrieved. Yao et al., ReAct: Synergizing Reasoning and Acting in Language Models (2022).
Task decomposition (\"Prompts by Task Type\") applies least-to-most prompting: Breaking a complex problem into subproblems and solving them sequentially, each building on the last. This is the research version of \"plan, then implement one slice.\" Zhou et al., Least-to-Most Prompting Enables Complex Reasoning in Large Language Models (2022).
Explicit planning (\"Explore → Plan → Implement\") is directly supported by plan-and-solve prompting, which addresses missing-step failures in zero-shot reasoning by extracting a plan before executing. The phased structure prevents the model from jumping to code before understanding the problem. Wang et al., Plan-and-Solve Prompting: Improving Zero-Shot Chain-of-Thought Reasoning by Large Language Models (2023).
Session reflection (\"What did we learn?\", /ctx-reflect) is a form of verbal reinforcement learning: Improving future performance by persisting linguistic feedback as memory rather than updating weights. This is exactly what LEARNINGS.md and DECISIONS.md provide: a durable feedback signal across sessions. Shinn et al., Reflexion: Language Agents with Verbal Reinforcement Learning (2023).
These aren't prompting \"hacks\" that you will find in the \"1000 AI Prompts for the Curious\" listicles: They are applications of foundational principles:
- Decomposition,
- Abstraction,
- Ensemble Reasoning,
- Search,
- and Constrained Optimization.
They work because language models are, at their core, optimization systems navigating probabilistic landscapes.

Mode When the file is included always Every prompt, unconditionally auto When the prompt keywords match the file's description manual Only when the user explicitly names the file Which mode to pick depends on the AI tool you use, because the two tool families consume steering very differently.
Claude Code and Codex: prefer inclusion: always for rules that must fire reliably. These tools have two delivery channels:
- The plugin's
PreToolUse hook runs ctx agent with an empty prompt, so only always files match and get injected automatically on every tool call. - The
ctx_steering_get MCP tool, registered automatically when the ctx plugin is installed. Claude can call this tool mid-task to fetch auto or manual files matching a specific prompt. Verify with claude mcp list; look for ctx: ✓ Connected.
Use always for invariants and anything that must fire every session. Use auto for situational rules where \"Claude fetches this when the prompt is relevant\" is the right behavior; those still land, just on Claude's judgment. Use manual for reference libraries you'll name explicitly.
Cursor, Cline, Kiro: auto is the natural default. These tools read .cursor/rules/, .clinerules/, or .kiro/steering/ natively and resolve the description match on their own, so auto files fire when the prompt matches. manual files load on explicit invocation. always still works but consumes context budget on every turn.
Mixed setups: if a rule must fire on Claude Code, pick always, even if it's overkill for your Cursor setup. The context budget cost is small; the alternative (silently not firing) is worse.
","path":["Home","Customization","Steering Files"],"tags":[]},{"location":"home/steering/#two-families-of-ai-tools-two-delivery-paths","level":2,"title":"Two Families of AI Tools, Two Delivery Paths","text":"Not every AI tool consumes steering the same way. ctx handles two tool families differently, and it's worth knowing which family your editor is in before you wonder why a rule isn't firing.
Native-rules tools (Cursor, Cline, Kiro) have a built-in rules primitive. They read a specific directory (.cursor/rules/, .clinerules/, .kiro/steering/) and apply the rules they find there. ctx handles these via ctx steering sync, which exports your files into the tool-native format. Run sync whenever you edit a steering file.
Hook + MCP tools (Claude Code, Codex) have no native rules primitive, so ctx steering sync is a no-op for them. Instead, ctx delivers steering through two non-sync channels:
- Automatic injection via a
PreToolUse hook. The ctx setup claude-code plugin wires a hook that runs ctx agent --budget 8000 before each tool call. ctx agent loads your steering files, filters them by the active prompt, and includes matching bodies in the context packet it prints. Claude Code feeds that output back into its context. Every tool call, automatically. - On-demand via the
ctx_steering_get MCP tool. The ctx MCP server exposes a tool Claude can call mid-task to fetch matching steering files for a specific prompt. Claude decides when to call it; it's not automatic.
Both channels activate when you run ctx setup claude-code --write. After that, steering just works for Claude Code.
Practical takeaway:
- Using Cursor/Cline/Kiro only? Run
ctx steering sync after edits. - Using Claude Code or Codex only? Never run
sync; the hook+MCP pipeline handles it. - Using both? Run
sync for the native-rules tools; the hook+MCP pipeline covers Claude Code automatically.

Claude Code's /loop runs all iterations within the same session. This means:
- State leaks between iterations: The context window accumulates output from every previous iteration. The agent \"remembers\" things it saw earlier (even if they were never persisted to
.context/). - Token budget degrades: Each iteration adds to the context window, leaving less room for actual work in later iterations.
- Not ergonomic for long runs: Users report that the built-in loop is less predictable for 10+ iteration runs compared to a shell loop.

This page is for operators: people running a hub for themselves or a team, not people writing to a hub someone else is running.
If you have not read it yet, start with the ctx Hub overview. It explains what the hub is, the two user stories it supports (personal cross-project brain vs small trusted team), and what it does not do. A client-side tour is in Getting Started.
Operator Cheat Sheet
- The hub fans out four entry types only:
decision, learning, convention, task. Journals, scratchpad, and other local state are out of scope. - Identity is per-project, not per-user. Attribution is limited to
Origin, which is self-asserted by the publishing client. - The data model is an append-only JSONL log plus two small JSON sidecar files. Nothing is rewritten in place.
","path":["Operations","Hub","Hub Operations"],"tags":[]},{"location":"operations/hub/#data-directory-layout","level":2,"title":"Data Directory Layout","text":"The hub stores everything under a single data directory (default ~/.ctx/hub-data/, override with --data-dir).

Invariants:
entries.jsonl is append-only. Every line is a valid JSON object. Corrupt lines are fatal at startup: fix or truncate before restart. meta.json is authoritative for the next sequence number. On restart, the hub reads the last valid line of entries.jsonl and refuses to start if the sequences disagree. clients.json holds hashed client tokens; losing it invalidates all client registrations.

--stop sends SIGTERM to the PID in hub.pid, waits for in-flight RPCs to drain, then exits. If the daemon is wedged, remove hub.pid and send SIGKILL manually. entries.jsonl is crash-safe, so you will not lose accepted writes.

For a consistent snapshot across all three files, stop the hub, copy, then start again, or use a filesystem-level snapshot (LVM, ZFS, Btrfs).
Restore:
ctx hub stop # Stop the hub\ncp backups/entries-2026-04-10.jsonl <data-dir>/entries.jsonl\ncp backups/meta-2026-04-10.json <data-dir>/meta.json\ncp backups/clients-2026-04-10.json <data-dir>/clients.json\nctx hub start --daemon\n

You are an autonomous architecture exploration agent. Your job is to\nsystematically build and evolve architecture documentation across all\nrepositories in this workspace using ctx skills.\n\n## Execution Protocol\n\n### Step 1: Read State\n\nRead `.arch-explorer/manifest.json`. This tells you:\n- Which repos exist and their order\n- What has been done per repo (`progress` object)\n- Which repo to work on next (`current_repo_index`)\n\n### Step 2: Pick the Next Unit of Work\n\n**Strategy: depth-first, sequential.**\n\nFind the current repo (by `current_repo_index`). Determine its next\nphase from the progression below. If all phases are exhausted for this\nrepo (convergence score >= 0.85 or 3+ frontier runs with no new\nfindings), advance `current_repo_index` and pick the next repo.\n\n### Phase Progression (per repo)\n\nEach repo progresses through these phases in order:\n\n| Phase | Skill | Prerequisite |\n|-------|-------|-------------|\n| `bootstrap` | `ctx init` + `/ctx-architecture` | None |\n| `principal` | `/ctx-architecture principal` | bootstrap done |\n| `enriched` | `/ctx-architecture-enrich` | principal done, GitNexus indexed |\n| `frontier-N` | `/ctx-architecture` (re-run) | enriched done |\n\n**`bootstrap` is a single composite unit:** `ctx init` followed by\nstructural analysis. This is the ONLY phase that combines two actions.\nNo other phase may chain actions.\n\n**Frontier runs** are numbered: `frontier-1`, `frontier-2`, etc.\nEach frontier run reads CONVERGENCE-REPORT.md and picks unexplored\nareas. The skill handles this automatically.\n\nAfter the third frontier run OR when convergence >= 0.85, apply\n**conceptual lenses** (one per run):\n\n| Lens | Focus Areas |\n|------|-------------|\n| `security` | Auth flows, input validation, secrets, attack surfaces, trust boundaries |\n| `performance` | Hot paths, caching, concurrency, resource lifecycle, allocation patterns |\n| `stability` | Error handling, retries, graceful degradation, circuit breakers, timeouts |\n| `observability` | Logging, metrics, tracing, alerting, debugging affordances |\n| `data-integrity` | Storage, serialization, migrations, consistency, backup, recovery |\n\nFor lens runs, prepend the lens context as an explicit instruction to\nthe skill invocation:\n\n> \"Focus exploration on security: auth flows, input validation, secrets,\n> attack surfaces, trust boundaries.\"\n\nDo NOT wait for the skill to ask what to explore. Provide the lens\nfocus as input upfront.\n\n### Step 3: Do the Work\n\n1. `cd` into the sub-repo directory (`~/WORKSPACE/<repo-name>`, NOT\n `~/WORKSPACE` itself).\n2. Verify `CTX_DIR` already points at THIS sub-repo's `.context/`:\n\n ```bash\n test \"$CTX_DIR\" = \"$PWD/.context\" || {\n echo \"STOP: CTX_DIR=$CTX_DIR but this sub-repo needs $PWD/.context.\"\n echo \"Re-launch the agent with CTX_DIR set to the sub-repo:\"\n echo \" cd $PWD && CTX_DIR=\\\"\\$PWD/.context\\\" claude --print 'Follow .arch-explorer/PROMPT.md' --allowedTools '*'\"\n exit 1\n }\n ```\n\n If it fails, STOP. The agent cannot change `CTX_DIR` for itself:\n child shells and skill invocations inherit the parent Claude\n process environment, which only the caller can control. Do not\n proceed, do not run `ctx` commands, do not skip the check.\n3. If phase is `bootstrap`:\n - Run `ctx init`, confirm `.context/` exists.\n - Then run `/ctx-architecture` (structural baseline).\n4. If phase is `principal` or `frontier-*`:\n - Run `/ctx-architecture` (add `principal` argument for principal phase).\n - The skill will read existing artifacts and build on them.\n5. If phase is `enriched`:\n - Verify GitNexus is connected: call `mcp__gitnexus__list_repos`.\n - Success = non-empty list returned with no error.\n - If GitNexus unavailable, log as `enriched-skipped` and advance\n to `frontier-1`.\n - Run `/ctx-architecture-enrich`.\n6. If phase is a lens run (`lens-security`, etc.):\n - Run `/ctx-architecture` with lens focus prepended as instruction\n (see lens table above for exact wording).\n\n### Step 4: Extract Results\n\nAfter the skill completes, gather:\n\n- **Convergence score**: from `map-tracking.json`, computed as:\n average of all module `confidence` values (0.0-1.0). If\n `map-tracking.json` is missing or has no confidence values,\n record `null` and log a warning.\n- **Frontier count**: from CONVERGENCE-REPORT.md, count the number\n of listed unexplored areas. If CONVERGENCE-REPORT.md is missing,\n record `frontier_count: null` and log a warning. Treat missing\n as \"exploration should continue\" (do not stall).\n- **Key findings**: 2-3 bullet points of what was discovered or\n changed in this run (new modules mapped, danger zones found, etc.)\n- **New artifacts**: list any new files created in `.context/`\n\n### Step 5: Update Tracking\n\nUpdate `.arch-explorer/manifest.json`:\n\n```json\n{\n \"progress\": {\n \"ctx\": {\n \"phases_completed\": [\"bootstrap\", \"principal\"],\n \"current_phase\": \"enriched\",\n \"lenses_explored\": [],\n \"last_run\": \"2026-04-07T14:00:00Z\",\n \"convergence_score\": 0.72,\n \"frontier_count\": 3,\n \"total_runs\": 2,\n \"findings_summary\": \"14 modules mapped, 3 danger zones, 2 extension points\"\n }\n }\n}\n```\n\nAppend to `.arch-explorer/run-log.md`:\n\n```markdown\n## 2026-04-07T14:00:00Z / ctx / principal\n\n**Phase:** principal\n**Convergence:** 0.45 -> 0.72\n**Frontiers remaining:** 3\n**Key findings:**\n- Identified CLI dispatch as primary bottleneck (fan-out to 12 subsystems)\n- Security: context files readable by any process (no access control)\n- Strategic recommendation: extract context engine into library package\n\n**Artifacts updated:** ARCHITECTURE-PRINCIPAL.md, DANGER-ZONES.md, map-tracking.json\n```\n\n### Step 6: Report and Stop\n\nPrint this exact format as the FINAL output of the invocation:\n\n```\n[arch-explorer] DONE\n repo: ctx\n phase: principal\n convergence: 0.72\n frontiers: 3\n runs_on_repo: 3\n next: ctx / enriched\n```\n\nThe `[arch-explorer] DONE` line is the terminal marker. After printing\nit, produce no further output. Execution is complete.\n\n## Rules\n\n1. **One unit per invocation.** The only composite unit is `bootstrap`\n (init + structural). All other phases are exactly one skill run.\n2. **Additive only.** Never delete or overwrite existing artifacts.\n The skills already handle incremental updates.\n3. **No duplicated work.** Read manifest before acting. If a phase is\n already recorded as completed, skip it.\n4. **Log everything.** Every run gets a run-log entry, even failures\n and skips.\n5. **Fail gracefully.** If a skill fails (missing GitNexus, broken repo,\n etc.), log the failure with reason and advance to the next phase or\n repo. Don't retry in the same invocation.\n6. **Respect ctx conventions.** Each repo gets its own `.context/`\n directory. Never write architecture artifacts outside `.context/`.\n\n## Stopping Logic\n\nA repo is considered \"explored\" when ANY of these is true:\n- Convergence score >= 0.85 (from map-tracking.json)\n- 3+ frontier runs produced no new findings (frontier_count unchanged\n across consecutive runs)\n- All 5 lenses have been applied\n- Convergence score is `null` after 3 attempts (artifacts aren't being\n generated properly; log warning and move on)\n\nWhen a repo is explored, advance `current_repo_index` in the manifest.\n\n## When All Repos Are Done\n\nWhen every repo has reached its stopping condition, print:\n\n```\n[arch-explorer] ALL DONE\n - ctx: 0.92 convergence, 8 runs, 5 lenses\n - portal: 0.87 convergence, 6 runs, 3 lenses\n ...\n```\n

Save each report as\na separate markdown file under `./ideas/` (or another directory if you prefer).\n\nUse read-only agents (subagent_type: Explore) for all analyses. No code changes.\n\nFor each report, use this structure:\n- Executive Summary (2-3 sentences + severity table)\n- Findings (grouped, with file:line references)\n- Ranked Recommendations (high/medium/low priority)\n- Methodology (what was examined, how)\n\nKeep reports actionable: every finding should suggest a concrete fix or next step.\n\n## Analyses to Run\n\n### 1. Extractable Patterns (session mining)\nSearch session JSONL files, journal entries, and task archives for repetitive\nmulti-step workflows. Count frequency of bash command sequences, slash command\nusage, and recurring user prompts. Identify patterns that could become skills\nor scripts. Cross-reference with existing skills to find coverage gaps.\nOutput: ranked list of automation opportunities with frequency data.\n\n### 2. Documentation Drift (godoc + inline)\nCompare every doc.go against its package's actual exports and behavior. Check\ninline godoc comments on exported functions against their implementations.\nScan for stale TODO/FIXME/HACK comments. Check package-level comments match\npackage names. Output: drift items ranked by severity with exact file:line refs.\n\n### 3. Maintainability\nLook for: functions >80 lines that have logical split points; switch blocks\nwith >5 cases that could be table-driven or extracted; inline comments that\nsay \"step 1\", \"step 2\" or similar (sign the block wants to be a function);\nfiles with >400 lines; packages with flat structure that could benefit from\nsub-packages; functions that seem misplaced in their file. Do NOT flag\nthings that are fine as-is just because they could theoretically be different.\nOutput: concrete refactoring suggestions, not style nitpicks.\n\n### 4. Security Review\nThis is a CLI app: focus on CLI-relevant attack surface, not web OWASP:\nfile path traversal (does user input flow into file paths unsanitized?),\ncommand injection (does user input flow into exec calls?), symlink following\n(does the tool follow symlinks when writing to .context/?), permission\nhandling (are file permissions set correctly?), sensitive data in outputs\n(do any commands leak secrets or session content?). Output: findings with\nseverity ratings and exploit scenarios.\n\n### 5. Blog Theme Discovery\nRead existing blog posts for style and narrative voice. Analyze git log,\nrecent session discussions, and DECISIONS.md for story arcs worth writing\nabout. Suggest 3-5 blog post themes with: title, angle, target audience,\nkey commits/sessions to reference, and a 2-sentence pitch. Prioritize\nthemes that build a coherent narrative across posts.\n\n### 6. Roadmap & Value Opportunities\nBased on current features, recent momentum, and gaps found in other analyses:\nwhat are the highest-value improvements? Consider: user-facing features,\ndeveloper experience, integration opportunities, and low-hanging fruit.\nOutput: prioritized list with effort/impact estimates (not time estimates).\n\n### 7. User-Facing Documentation\nEvaluate README, help text, and any user docs. Suggest improvements\nstructured as use-case pages: the problem, how ctx solves it, typical\nworkflow, gotchas. Identify gaps where a user would get stuck without\nreading source code. Output: list of documentation gaps and suggested\npage outlines.\n\n### 8. Agent Team Strategies\nBased on the codebase structure, suggest 2-3 agent team configurations for\nupcoming work sessions. For each: team composition (roles, agent types),\ntask distribution strategy, coordination approach, and which types of work\nit suits. Ground suggestions in actual project patterns, not generic advice.\n

Do Not Skip This Section
This is not optional hardening:
An unattended agent with unrestricted OS access is an unattended shell with unrestricted OS access.
The allowlist above is a strong first layer, but do not rely on a single runtime boundary.
For unattended runs, enforce isolation at the infrastructure level:
Layer What to enforce User account Run the agent as a dedicated unprivileged user with no sudo access and no membership in privileged groups (docker, wheel, adm). Filesystem Restrict the project directory via POSIX permissions or ACLs. The agent should have no access to other users' files or system directories. Container Run inside a Docker/Podman sandbox. Mount only the project directory. Drop capabilities (--cap-drop=ALL). Disable network if not needed (--network=none). Never mount the Docker socket and do not run privileged containers. Prefer rootless containers. Virtual machine Prefer a dedicated VM with no shared folders, no host passthrough, and no keys to other machines. Network If the agent does not need the internet, disable outbound access entirely. If it does, restrict to specific domains via firewall rules. Resource limits Apply CPU, memory, and disk limits (cgroups/container limits). A runaway loop should not fill disk or consume all RAM. Self-modification Make instruction files read-only. CLAUDE.md, .claude/settings.local.json, and .context/CONSTITUTION.md should not be writable by the agent user. If using project-local hooks, protect those too. A minimal Docker setup for overnight runs:
docker run --rm \\\n --network=none \\\n --cap-drop=ALL \\\n --memory=4g \\\n --cpus=2 \\\n -v /path/to/project:/workspace \\\n -w /workspace \\\n your-dev-image \\\n ./loop.sh 2>&1 | tee /tmp/loop.log\n
Defense in Depth
Use multiple layers together: OS-level isolation (the boundary the agent cannot cross), a permission allowlist (what Claude Code will do within that boundary), and CONSTITUTION.md (a soft nudge for the common case).

The generated script reads .context/loop.md, runs the tool, checks for completion signals, and loops until done or the cap is reached.
You can also use the /ctx-loop skill from inside Claude Code.
A Shell Loop Is the Best Practice
The shell loop approach spawns a fresh AI process each iteration, so the only state that carries between iterations is what lives in .context/ and git.
Claude Code's built-in /loop runs iterations within the same session, which can allow context window state to leak between iterations. This can be convenient for short runs, but it is less reliable for unattended loops.

Layer 2, semantic analysis (agent-driven): Does CONVENTIONS.md describe patterns the code no longer follows? Does DECISIONS.md contain entries whose rationale no longer applies?

Agent: ARCHITECTURE.md references `internal/handlers/` but that directory\n doesn't exist. I'll look at the actual source tree to find where\n handlers live now.\n
This happens reliably when the drift intersects the task. What is less reliable is the agent generalizing from one mismatch to \"there might be more stale references; let me run drift detection\" That leap requires the agent to know /ctx-drift exists and to decide the current task should pause for maintenance.
If you want that behavior, reinforce it:
Good catch. Yes, run /ctx-drift and clean up any other stale references.\n
Over time, agents that have seen this pattern will start offering proactively. But do not expect it from a cold start.

When an agent says \"this reference looks stale,\" it is usually right.
Semantic drift is more damaging than structural drift: ctx drift catches dead paths. But CONVENTIONS.md describing a pattern your code stopped following three weeks ago is worse. When you ask \"is our context clean?\", the agent can do both checks.
Use ctx status as a quick check: It shows file counts, token estimates, and drift warnings in a single glance. Good for a fast \"is everything ok?\" before diving into work.
Drift detection in CI: add ctx drift --json to your CI pipeline and fail on exit code 3 (violations). This catches constitution-level problems before they reach upstream.
Do not over-compact: Completed tasks have historical value. The --archive flag preserves them in .context/archive/ so you can search past work without cluttering active context.
Sync is cautious by default: Use --dry-run after large refactors, then apply.

Operation Behavior with external .context/ ctx status, agent, add ✅ Works. Operates on files inside CTX_DIR. Journal, scratchpad, hub ✅ Works. Same reason. ctx sync ⚠️ Scans the context repo, not the code repo. ctx drift ⚠️ Same. Reports nothing useful.

Now filepath.Dir(CTX_DIR) is the code repo, so code-aware operations scan the right tree. The actual files still live in the external repo and commit there. Add .context to the code repo's .gitignore (or .git/info/exclude) so the symlink itself isn't tracked by the code repo.
The basename guard is permissive about symlinks: it checks the declared name, not the resolved target, so a .context symlink pointing anywhere is accepted as long as the declared basename is .context.

Hook type: PreToolUse only (Claude Code first-class mechanism).
Examples in ctx:
ctx system block-non-path-ctx: Enforces the PATH invocation rule block-git-push.sh: Requires explicit user approval for pushes (project-local) block-dangerous-commands.sh: Prevents sudo, copies to ~/.local/bin (project-local)

When to use: Actionable reminders the user needs to see regardless of what they asked: Stale backups, unimported sessions, resource warnings.
Hook type: UserPromptSubmit (runs before the agent sees the prompt).
Examples in ctx:
ctx system check-journal: Unexported sessions and unenriched entries ctx system check-context-size: Context capacity warning ctx system check-resources: Resource pressure (memory, swap, disk, load): DANGER only ctx system check-freshness: Technology constant staleness warning
Trade-off: Noisy if overused. Every VERBATIM relay adds a preamble before the agent's actual answer. Throttle with once-per-day markers or adaptive frequency.
Key detail: The phrase IMPORTANT: Relay this ... VERBATIM is what makes this work. Without it, agents tend to process the information internally and never surface it. The explicit instruction is the pattern: the box-drawing is just fancy formatting.

Examples in ctx:

This recipe assumes you've read the ctx Hub overview and the Multi-machine setup. HA only makes sense in the \"small trusted team\" story; a personal cross-project brain on one workstation does not need three Raft peers.
Raft-Lite
ctx uses Raft only for leader election, not for data consensus. Entry replication happens via sequence-based gRPC sync on the append-only JSONL store. This is simpler than full Raft log replication and is possible because the store is append-only and clients are idempotent. The implication: a write accepted by the leader is durable on the leader immediately; followers catch up asynchronously. If the leader crashes between accepting a write and replicating it, that write can be lost. Do not use the hub as a bank ledger.

An on-call engineer records a learning from a 3 AM incident; the rest of the team inherits the lesson without needing to read the postmortem.
Concrete payoff:
- Team conventions propagate without needing a wiki or chat.
- Lessons from one team member become available to everyone else's agent context packets automatically.
- Cross-project decisions (shared libraries, deployment patterns, naming rules) live in a single log the whole team reads.
Trust model: the hub assumes everyone holding a client token is friendly. There is no per-user attribution you can rely on, Origin is self-asserted by the publishing client, and there is no read ACL beyond the subscription filter. Treat the hub like a team wiki: useful because everyone can write to it, not because it can prove who wrote what.
Operational shape: run the hub on a LAN host (or a three-node HA cluster for redundancy), put TLS in front of it for anything beyond a home LAN, distribute client tokens over a trusted channel.

Subscribe to task only if you want cross-project todos. The four subscribable types are decision, learning, convention, task. Tasks are usually project-local; subscribing makes every hub-shared task from every project show up in every other project's agent packet. That's probably not what you want. Skip task in ctx connection subscribe unless you have a specific reason.
Run the hub as a user-level daemon so you don't have to remember to start it. On Linux with systemd:
# ~/.config/systemd/user/ctx-hub.service\n[Unit]\nDescription=ctx Hub (personal)\n\n[Service]\nType=simple\nExecStart=/usr/local/bin/ctx hub start\nRestart=on-failure\n\n[Install]\nWantedBy=default.target\n

Local storage is fine; no TLS needed. The hub runs on localhost. No one else is on the network. Skip the TLS setup from the Multi-machine recipe; it's relevant when the hub is on a LAN host serving multiple workstations, not when it's a personal daemon.

Prerequisites:
- A running
ctx Hub on a LAN host or internal server everyone on the team can reach. See Multi-machine setup for the deployment guide. - Each team member has
ctx installed and has ctx connection register-ed their working projects with the hub. - Each project on each workstation has been activated for the shell with
eval \"$(ctx activate)\". The hub server (ctx hub start, etc.) doesn't need this — but the client side (ctx connection ..., ctx add --share) lives in a project and does. If you skip activation, those client commands fail with Error: no context directory specified. See Activating a Context Directory.

- Load: agents pick up shared entries automatically via the auto-sync hook and the
--include-hub flag in the PreToolUse hook pipeline.

- ✅ Policy decisions that apply to all services (naming, API versioning, error-message format).
- ❌ Internal implementation decisions inside a single service (\"chose a map over a slice here because lookups dominate\").
- ❌ One-off tactical calls for a specific PR.
Learnings:
- ✅ Gotchas, surprising behavior, flaky infrastructure quirks, anything you'd tell a teammate over coffee with \"watch out for X\".
- ✅ Lessons from incidents, right after the postmortem is the highest-value time to share.
- ❌ Internal debugging notes that only make sense with context from your current branch.
Conventions:
- ✅ Repo layout, commit message format, pre-commit hooks, review expectations.
- ✅ Language-level style decisions that apply across services.
- ❌ Per-service idioms (\"in
billing/ we prefer…\").
Tasks: almost always project-local. Don't subscribe to task unless the team has a specific reason (e.g., a cross-cutting migration you want visible everywhere).

On-call engineer Alice gets paged: the payment service starts returning 500s after a dependency update. After an hour she finds the culprit: a breaking change in a transitive gRPC dep that only manifests under high concurrency. Postmortem on Tuesday, but right now she records the learning:
ctx learning add --share \\\n --context \"Payment service 3 AM incident, 2026-04-03\" \\\n --lesson \"grpc-go v1.62+ changes DialContext behavior under high \\\n concurrency: connections from a single channel can deadlock if the \\\n server emits GOAWAY mid-stream. Symptom: 500 errors cluster in \\\n 30s bursts, no error in grpc client logs.\" \\\n --application \"Any service on grpc-go. Pin to v1.61 or patch with \\\n keepalive: https://github.com/grpc/grpc-go/issues/...\" \n
By Tuesday morning, every other engineer's agent context packet contains this learning. When Bob starts work on the ledger service (which also uses grpc-go), his Claude Code session already knows about the gotcha without Bob having to read the incident channel.
Wednesday, cross-service decision
The team agrees on a new pattern for API versioning: header-based instead of URL-based. Platform lead Carol records the decision:
ctx decision add --share \\\n --context \"Need consistent API versioning across all 6 services. \\\n Current URL-based /v1/ isn't working for gradual rollouts.\" \\\n --rationale \"Header-based versioning lets us route by header at the \\\n edge, which makes canary rollouts trivial. URL-based versioning \\\n forces clients to update their paths.\" \\\n --consequence \"All new endpoints use X-API-Version header. \\\n Existing /v1/ endpoints stay. Deprecation schedule in q3.\" \\\n \"Use header-based API versioning for new endpoints\"\n
Every engineer's next session knows about this decision automatically. When Dave starts adding endpoints to the inventory service on Thursday, Claude already prompts him for the header pattern instead of defaulting to /v1/.
Friday, convention drift caught at review
Dave notices that his PR auto-formatted some error messages to end with periods. He recalls the team convention is \"no trailing period\" but can't remember where it was documented. He runs ctx connection status, sees the hub is healthy, greps his local .context/hub/conventions.md, and finds:
## [2026-03-12] Error message format\nLowercase start, no trailing period, single sentence.\n
He fixes the PR. No lookup on the wiki, no question in chat, no context-switch penalty.

The team lead or platform engineer should be the person who explicitly --shares cross-cutting decisions. Other team members share learnings freely but should ask \"should this be a decision?\" in review before --shareing a decision. This keeps the decision stream signal-rich.
Publish postmortem learnings immediately, not after the meeting. The postmortem itself is a document; the actionable rules that come out of it belong on the hub, and they should land within an hour of the incident. \"Share fast, edit later\" is the rule.
Delete noisy entries, don't tolerate them. The hub is append-only, but the .context/hub/ mirror on each client is just markdown. If a shared learning turns out to be wrong or obsolete, remove it from local mirrors and stop the hub daemon to truncate entries.jsonl (see Hub operations). Noisy shared feeds lose trust fast.
Don't subscribe every project to every type. For backend engineers, subscribing to decision + learning + convention is usually right. For platform or DevOps projects, adding task makes sense. For a prototype or experiment project, subscribing only to convention might be enough.
Run a single hub, not one per team. If two teams need to share knowledge, they should share a hub. Splitting hubs by team creates silos, which is often exactly the thing you were trying to solve.

The agent was present for the trade-off discussion. It fills in the structured fields from what it observed, which is hard to reconstruct later as a terminal one-liner.
When multiple options were considered, the agent includes rejected alternatives in the rationale automatically.
The /ctx-decision-add skill also guides you through the fields interactively. For quick decisions, it supports a Y-statement:

You said one sentence. The agent produced a structured entry with all three fields filled from the session context.

Agents trained on the ctx playbook naturally surface persist-worthy items at breakpoints, even without invoking the skill explicitly.
A conversational prompt like \"anything worth saving?\" or \"let's wrap up\" can trigger the same review.
The skill provides a structured checklist, but the behavior is available through natural conversation.
At natural breakpoints (after completing a feature, fixing a bug, or before ending a session) use /ctx-reflect to identify items worth persisting.
/ctx-reflect\n
The skill walks through learnings, decisions, tasks, and session notes, skipping categories with nothing to report. The output includes specific commands for each suggested persist:

You ask, the agent acts:
You say What the agent does \"What have we learned this session?\" Reviews recent work, identifies learnings, offers to persist \"Save that as a decision\" Captures the trade-off you just discussed with structured fields \"Any gotchas worth remembering?\" Scans recent work for non-obvious lessons \"Record that convention\" Adds the pattern you just agreed on to CONVENTIONS.md \"Let's wrap up\" Runs through the reflect checklist conversationally Example exchange:
You: \"What did we learn from that debugging session?\"\n\nAgent: \"We discovered three things worth persisting:\n 1. Hook subprocesses can't propagate env vars to the parent.

The cooldown logic must check file mtime, not just existence.\n Want me to save these as learnings?\"\n\nYou: \"Yes, all of them.\"\n\nAgent: \"Done. Added all three to LEARNINGS.md with structured fields.\"\n
The agent can also be proactive without being asked. The playbook encourages agents to persist context at natural milestones.
You may see:
- After fixing a tricky bug: \"I noticed this was a non-obvious issue. Want me to save it as a learning?\"
- After choosing between approaches: \"We just made a trade-off between file-based tokens and IPC. Should I record this as a decision?\"
- At session milestones: the agent checks what is worth persisting and offers a brief summary.
When agents run unattended (no human in the loop), they may persist directly:
- \"I've added the subprocess env var gotcha to
LEARNINGS.md so we don't hit it again.\" - \"Recorded the decision to use file-based tokens over env vars in
DECISIONS.md.\" - \"Marked the cooldown task done and added a follow-up for TTL cleanup.\"
This is behavior by design.
The playbook's self-check prompt, \"If this session ended right now, would the next session know what happened?\" drives agents to persist early and often rather than waiting for explicit instructions.

Both approaches produce the same structured entries in the same context files.
- The conversational approach is the natural fit for interactive sessions;
- the CLI commands are better suited for scripts, hooks, and automation pipelines.

The alternatives you considered and the reasons you rejected them fade quickly. Capture trade-offs while they are fresh.
- Learnings should fail the Gemini test. If someone could find it in a 5-minute Gemini search, it does not belong in
LEARNINGS.md. - Conventions earn their place through repetition. Add a convention the third time you see a pattern, not the first.
- Use
/ctx-reflect at natural breakpoints. The checklist catches items you might otherwise lose. - Keep the entries self-contained. Each entry should make sense on its own. A future session may load only one due to token budget constraints.
- Reindex after every hand edit. It takes less than a second. A stale index causes AI tools to miss entries.
- Prefer the structured fields. The verbosity forces clarity. A decision without a rationale is just a fact. A learning without an application is just a story.
- Talk to your agent, do not type commands. In interactive sessions, the conversational approach is the recommended way to capture knowledge. Say \"save that as a learning\" or \"any decisions worth recording?\" and let the agent handle the structured fields. Reserve the CLI commands for scripting, automation, and CI/CD pipelines where there is no agent in the loop.
- Trust the agent's proactive instincts. Agents trained on the
ctx playbook will offer to persist context at milestones. A brief \"want me to save this?\" is cheaper than re-discovering the same lesson three sessions later. -
Relax provenance per-project if --session-id, --branch, or --commit are impractical (e.g., manual notes outside an AI session). Add to .ctxrc:
provenance_required:\n session_id: false # allow entries without --session-id\n branch: true # still require --branch\n commit: true # still require --commit\n
Default is all three required. Only human config relaxes: Agents cannot bypass, and that's by design.

Using a Different .context Directory
The .context/ directory doesn't have to live inside your project. Point ctx to an external folder by exporting CTX_DIR (the only declaration channel).
Useful when context must stay private while the code is public, or when you want to commit notes to a separate repo.
Caveats (the recipe covers both with workarounds):
- Code-aware operations degrade silently.
ctx sync, ctx drift, and the memory-drift hook read the codebase from dirname(CTX_DIR). With an external .context/, that's the context repo, not your code repo. They scan the wrong tree without erroring. The recipe shows a symlink workaround that keeps both healthy. - One
.context/ per project, always. Sharing one directory across multiple projects corrupts journals, state, and secrets. For cross-project knowledge sharing (CONSTITUTION, CONVENTIONS, ARCHITECTURE, etc.) use ctx hub, not a shared .context/.
See External Context for the full recipe and Configuration for the resolver details.
For Claude Code, install the ctx plugin to get hooks and skills:
claude /plugin marketplace add ActiveMemory/ctx\nclaude /plugin install ctx@activememory-ctx\n
If you only need the core files (useful for lightweight setups), use the --minimal flag:
ctx init --minimal\n

\"Do you remember?\"
A correctly configured tool responds with specific context: current tasks from TASKS.md, recent decisions, and previous session topics. It should not say \"I don't have memory\" or \"Let me search for files.\"
This question checks the passive side of memory. A properly set-up agent is also proactive: it treats context maintenance as part of its job:
- After a debugging session, it offers to save a learning.
- After a trade-off discussion, it asks whether to record the decision.
- After completing a task, it suggests follow-up items.
The \"do you remember?\" check verifies both halves: recall and responsibility.
For example, after resolving a tricky bug, a proactive agent might say:
That Redis timeout issue was subtle. Want me to save this as a *learning*\nso we don't hit it again?\n
If you see behavior like this, the setup is working end to end.
In Claude Code, you can also invoke the /ctx-status skill:
/ctx-status\n
This prints a summary of all context files, token counts, and recent activity, confirming that hooks are loading context.

Activate Each Machine
Run eval \"$(ctx activate)\" from the project root on every machine that reads or writes the scratchpad: after each ctx init, or after each clone on machine B. If you skip it, ctx pad ... fails with Error: no context directory specified. See Activating a Context Directory.
Finding Your Key File
The key is always at ~/.ctx/.ctx.key - one key, one machine.
Treat the Key like a Password
The scratchpad key is the only thing protecting your encrypted entries.
Store a backup in a secure enclave such as a password manager, and treat it with the same care you would give passwords, certificates, or API tokens.
Anyone with the key can decrypt every scratchpad entry.

Stage Tool What it does Skips if Where Import ctx journal import --all Converts session JSONL to Markdown File already exists (safe default) CLI or agent Enrich /ctx-journal-enrich-all Adds frontmatter, summaries, topic tags Frontmatter already present Agent only Rebuild ctx journal site --build Generates browsable static HTML N/A CLI only Obsidian ctx journal obsidian Generates Obsidian vault with wikilinks N/A CLI only Where Do You Run Each Stage?
Import (Steps 1 to 3) works equally well from the terminal or inside your AI assistant via /ctx-history. The CLI is fine here: the agent adds no special intelligence, it just runs the same command.
Enrich (Step 4) requires the agent: it reads conversation content and produces structured metadata.
Rebuild and serve (Step 5) is a terminal operation that starts a long-running server.

--keep-frontmatter=false Discards Enrichments
--keep-frontmatter=false discards enriched YAML frontmatter during regeneration.
Back up your journal before using this flag.
Each imported file contains session metadata (date, time, duration, model, project, git branch), a tool usage summary, and the full conversation transcript.
Re-importing is safe. Running ctx journal import --all only imports new sessions: Existing files are never touched. Use --dry-run to preview what would be imported without writing anything.
To re-import existing files (e.g., after a format improvement), use --regenerate: Conversation content is regenerated while preserving any YAML frontmatter you or the enrichment skill has added. You'll be prompted before any files are overwritten.
--regenerate Replaces the Markdown Body
--regenerate preserves YAML frontmatter but replaces the entire Markdown body with freshly generated content from the source JSONL.
If you manually edited the conversation transcript (added notes, redacted sensitive content, restructured sections), those edits will be lost.
BACK UP YOUR JOURNAL FIRST.
To protect entries you've hand-edited, you can explicitly lock them:
ctx journal lock <pattern>\n
Locked entries are always skipped, regardless of flags.
If you prefer to add locked: true directly in frontmatter during enrichment, run ctx journal sync to propagate the lock state to .state.json:
ctx journal sync\n
See ctx journal lock --help and ctx journal sync --help for details.

The /ctx-journal-enrich* skills add this structured frontmatter.
Locked entries are skipped by enrichment skills, just as they are by import. Lock entries you want to protect before running batch enrichment.
Batch enrichment (recommended):
/ctx-journal-enrich-all\n
The skill finds all unenriched entries, filters out noise (suggestion sessions, very short sessions, multipart continuations), and processes each one by extracting titles, topics, technologies, and summaries from the conversation.
It shows you a grouped summary before applying changes so you can scan quickly rather than reviewing one by one.
For large backlogs (20+ entries), the skill can spawn subagents to process entries in parallel.
Single-entry enrichment:
/ctx-journal-enrich twinkly\n/ctx-journal-enrich 2026-02-06\n
Each enriched entry gets YAML frontmatter like this:
---\ntitle: \"Implement Redis caching middleware\"\ndate: 2026-02-06\ntype: feature\noutcome: completed\ntopics:\n - caching\n - api-performance\ntechnologies:\n - go\n - redis\nlibraries:\n - go-redis/redis\nkey_files:\n - internal/cache/redis.go\n - internal/api/middleware/cache.go\n---\n

The site includes a date-sorted index, individual session pages with full conversations, search (press /), dark mode, and enriched titles in the navigation when frontmatter exists.
You can also serve an already-generated site without regenerating using ctx serve (serve-only, no regeneration).
The site generator requires zensical (pipx install zensical).

The agent earns its keep in enrich. It reads conversation content, understands what happened, and produces structured metadata. That is agent work, not CLI work.
You can also ask your agent to browse sessions conversationally instead of remembering flags:
What did we work on last week?\nShow me the session about Redis.\nImport everything to the journal.\n
This is convenient but not required: ctx journal source gives you the same inventory.
Where the agent genuinely helps is chaining the pipeline:
You: What happened last Tuesday?\nAgent: Last Tuesday you worked on two sessions:\n - bright-dancing-hopper (2h 10m): refactored the middleware\n pipeline and added Redis caching\n - quiet-flowing-dijkstra (18m): quick fix for a nil pointer\n in the config loader\n Want me to export and enrich them?\nYou: Yes, do it.\nAgent: Exports both, enriches, then proposes frontmatter.\n

session-abc123.md, session-abc123-p2.md, session-abc123-p3.md) with navigation links between them. The site generator can handle this. - Suggestion sessions can be separated. Claude Code can generate short suggestion sessions for autocomplete. These may appear under a separate section in the site index, so they do not clutter your main session list.
- Your agent is a good session browser. You do not need to remember slugs, dates, or flags. Ask \"what did we do yesterday?\" or \"find the session about Redis\" and it can map the question to recall commands.
Journal Files Are Sensitive
Journal files MUST be .gitignored.
Session transcripts can contain sensitive data such as file contents, commands, error messages with stack traces, and potentially API keys.
Add .context/journal/, .context/journal-site/, and .context/journal-obsidian/ to your .gitignore.

- At the start, you need the agent to load context and confirm it knows what is going on.
- At the end, you need to capture whatever the session produced before the conversation disappears.
Most ctx skills work conversationally: \"jot down: check DNS after deploy\" is as good as /ctx-pad add \"check DNS after deploy\". But session boundaries are different. They are well-defined moments with specific requirements, and partial execution is costly.
If the agent only half-loads context at the start, it works from stale assumptions. If it only half-persists at the end, learnings and decisions are lost.
This Is One of the Few Times Being Explicit Matters
Session ceremonies are the two bookend skills that mark these boundaries.

Completeness: Conversational triggers risk partial execution. The agent might load some files but skip the session history, or persist one learning but forget to check for uncommitted changes. The slash command runs the full ceremony.

The conversational trigger still works. But /ctx-remember guarantees the full ceremony runs:

Before You Start: Activate the Project
ctx commands (and the skills that call them) require CTX_DIR to be declared for the shell you're working in; ctx does not walk the filesystem to find .context/. Once per shell (or via your shell rc / direnv):
eval \"$(ctx activate)\"\n
If you skip this, every skill below will surface an error naming the fix. See Activating a Context Directory for the full recipe.
What Is a Readback?
A readback is a structured summary where the agent plays back what it knows:
- last session,
- active tasks,
- recent decisions.
This way, you can confirm it loaded the right context.
The term \"readback\" comes from aviation, where pilots repeat instructions back to air traffic control to confirm they heard correctly.
Same idea in ctx: The agent tells you what it \"thinks\" is going on, and you correct anything that's off before the work begins.
- Last session: topic, date, what was accomplished
- Active work: pending and in-progress tasks

Do you remember what we were working on?\n
This triggers the /ctx-remember skill. Behind the scenes, the assistant runs ctx agent --budget 4000, reads the files listed in the context packet (TASKS.md, DECISIONS.md, LEARNINGS.md, CONVENTIONS.md), checks ctx journal source --limit 3 for recent sessions, and then presents a structured readback.
The readback should feel like a recall, not a file system tour. If you see \"Let me check if there are files...\" instead of a confident summary, the context system is not loaded properly.
As an alternative, if you want raw data instead of a readback, run ctx status in your terminal or invoke /ctx-status for a summarized health check showing file counts, token usage, and recent activity.

/ctx-status\n
The status output shows which context files are populated, how many tokens they consume, and which files were recently modified. Look for:
- Empty core files:
TASKS.md or CONVENTIONS.md with no content means the context is sparse - High token count (over 30k): the context is bloated and might need
ctx compact - No recent activity: files may be stale and need updating
If the status looks healthy and the readback from Step 1 gave you enough context, skip ahead.
If something seems off (stale tasks, missing decisions...), spend a minute reading the relevant file before proceeding.

/ctx-next\n
The skill reads TASKS.md, checks recent sessions to avoid re-suggesting completed work, and presents 1-3 ranked recommendations with rationale.
It prioritizes in-progress tasks over new starts (finishing is better than starting), respects explicit priority tags, and favors momentum: continuing a thread from a recent session is cheaper than context-switching.
If you already know what you want to work on, state it directly:
Let's work on the session enrichment feature.\n
","path":["Recipes","Sessions","The Complete Session"],"tags":[]},{"location":"recipes/session-lifecycle/#step-4-do-the-work","level":3,"title":"Step 4: Do the Work","text":"This is the main body of the session: write code, fix bugs, refactor, research: whatever the task requires.
During this phase, a few ctx-specific patterns help:
Check decisions before choosing: when you face a design choice, check if a prior decision covers it.
Is this consistent with our decisions?\n
Constrain scope: keep the assistant focused on the task at hand.
Only change files in internal/cli/session/. Nothing else.\n
Use /ctx-implement for multistep plans: if the task has multiple steps, this skill executes them one at a time with build/test verification between each step.
Context monitoring runs automatically: the check-context-size hook monitors context capacity at adaptive intervals. Early in a session it stays silent. After 16+ prompts it starts monitoring, and past 30 prompts it checks frequently. If context capacity is running high, it will suggest saving unsaved work. No manual invocation is needed.
","path":["Recipes","Sessions","The Complete Session"],"tags":[]},{"location":"recipes/session-lifecycle/#step-5-commit-with-context","level":3,"title":"Step 5: Commit with Context","text":"When the work is ready, use the context-aware commit instead of raw git commit:
/ctx-commit\n
The Agent May Recommend Committing
You do not always need to invoke /ctx-commit explicitly.
After a commit, the agent may proactively offer to capture context:
\"We just made a trade-off there. Want me to record it as a decision?\"
This is normal: The Agent Playbook encourages persisting at milestones, and a commit is a natural milestone.
As an alternative, you can ask the assistant \"can we commit this?\" and it will pick up the /ctx-commit skill for you.
The skill runs a pre-commit build check (for Go projects, go build), reviews the staged changes, drafts a commit message focused on \"why\" rather than \"what\", and then commits.
After the commit succeeds, it prompts you:
**Any context to capture?**\n\n- **Decision**: Did you make a design choice or trade-off?\n- **Learning**: Did you hit a gotcha or discover something?\n- **Neither**: No context to capture; we are done.\n
If you made a decision, the skill records it with ctx decision add. If you learned something, it records it with ctx learning add including context, lesson, and application fields. This is the bridge between committing code and remembering why the code looks the way it does.
If source code changed in areas that affect documentation, the skill also offers to check for doc drift.
","path":["Recipes","Sessions","The Complete Session"],"tags":[]},{"location":"recipes/session-lifecycle/#step-6-reflect","level":3,"title":"Step 6: Reflect","text":"At natural breakpoints (after finishing a feature, resolving a complex bug, or before switching tasks) pause to reflect:
/ctx-reflect\n
Agents Reflect at Milestones
Agents often reflect without explicit invocation.
After completing a significant piece of work, the agent may naturally surface items worth persisting:
\"We discovered that $PPID resolves differently inside hooks. Should I save that as a learning?\"
This is the agent following the Work-Reflect-Persist cycle from the Agent Playbook.
You do not need to say /ctx-reflect for this to happen; the agent treats milestones as reflection triggers on its own.
The skill works through a checklist: learnings discovered, decisions made, tasks completed or created, and whether there are items worth persisting. It then presents a summary with specific items to persist, each with the exact command to run:
I would suggest persisting:\n\n- **Learning**: `$PPID` in PreToolUse hooks resolves to the Claude Code PID\n `ctx learning add --context \"...\" --lesson \"...\" --application \"...\" --session-id abc12345 --branch main --commit 68fbc00a`\n- **Task**: mark \"Add cooldown to ctx agent\" as done\n- **Decision**: tombstone-based cooldown with 10m default\n `ctx decision add \"...\" --session-id abc12345 --branch main --commit 68fbc00a`\n\nWant me to persist any of these?\n
The skill asks before persisting anything. You choose what to keep.
Not every commit needs reflection. A typo fix does not. But when you have been debugging for an hour and finally understand the root cause, that is worth a reflection checkpoint.

Ceremony Skills
/ctx-remember at session start and /ctx-wrap-up at session end are ceremony skills: Invoke them as explicit slash commands for completeness, not conversationally.
See Session Ceremonies for details on why these two skills are the exception to the conversational rule.
The skill gathers signal from git diff, recent commits, and the conversation, then proposes structured candidates for your approval. After you select which to keep, it persists them via ctx add and offers /ctx-commit if uncommitted changes remain.
Session transcripts are automatically captured by Claude Code and can be browsed later with ctx journal source and ctx journal source --show.

In practice, a session with a ctx-aware agent feels more like a conversation than a command sequence.
The agent knows the lifecycle and moves through it naturally, often without explicit invocation. Here is a realistic example:
You: Do you remember what we were working on?
Agent (loads context silently, presents structured readback):
Last session (Feb 7, caching-layer): we implemented the in-memory cache with\nTTL expiration and wrote tests for the eviction policy. \n\nYou have 3 pending tasks; the biggest one is adding Redis as a backend.\n\nRecent decision:<br>\nwe chose LRU over LFU because the access pattern is mostly recency-based.\n\nWant to continue with the Redis backend, or tackle something else?\n
You: Let's work on the Redis caching backend.
Agent (picks up the task, begins implementation):
Got it. I see the task in TASKS.md: \"Add Redis backend for cache layer.\"\n\nI will start with the connection pool setup. Only touching\n`internal/cache/redis/` for now.\n
(The agent works... writes code, runs tests, iterates.)
Agent (after implementing the connection pool and choosing a retry strategy):
The connection pool is working. I went with exponential backoff with jitter\nfor retries instead of fixed intervals; it handles thundering herd better\nunder reconnection storms. That is a design choice worth recording. \n\nWant me to save it as a decision?\n
You: Yes, go ahead.
Agent:
Done. Added to DECISIONS.md: \"Exponential backoff with jitter for Redis\nreconnection, to avoid thundering herd on pool recovery.\"\n
(More work happens... the agent implements the cache read/write paths.)
You: What else did we learn during this session?
Agent:
A few things worth capturing:\n\n* **Learning**: Redis `SET` with `NX` and `PX` flags handles atomic\n set-if-not-exists with TTL in a single call. No need for a separate\n `EXPIRE` command. We initially did it in two calls and hit a race condition.\n* **Learning**: The `go-redis` library's `PoolSize` default is 10 per CPU.\n For our workload, explicit sizing at 20 was more predictable.\n* **Task update**: The connection pool subtask is done; the read/write path\n is implemented but needs integration tests.\n\nWant me to persist these?\n
You: Yes. And let's wrap up.
Agent (reflects and persists... all in one flow):
Persisted:\n\n* 2 learnings added to LEARNINGS.md\n* Marked \"connection pool setup\" done in TASKS.md\n* Added \"write integration tests for Redis cache\" as a new task\n\nContext is up to date. You are good to close.\n
Notice What Happened
In the above workflow, the user never typed /ctx-reflect or ctx learning add.
The agent moved through Load, Orient, Pick, Work, Commit, and Reflect driven by natural conversation.
\"Let's wrap up\" was enough to trigger the full reflect-and-persist flow.
The agent surfaced persist-worthy items at milestones: after a design choice, after discovering a gotcha: without waiting to be asked.
This is the intended experience.
The commands and skills still exist for when you want precise control, but the agent is a proactive partner in the lifecycle, not a passive executor of slash commands.

- Load:
/ctx-remember: load context and confirm readback - Orient:
/ctx-status: check file health and token usage - Pick:
/ctx-next: choose what to work on - Work: implement, test, iterate (scope with \"only change X\")
- Commit:
/ctx-commit: commit and capture decisions/learnings - Reflect:
/ctx-reflect: identify what to persist (at milestones) - Wrap up:
/ctx-wrap-up: end-of-session ceremony
Conversational equivalents: you can drive the same lifecycle with plain language:
Step Slash command Natural language Load /ctx-remember \"Do you remember?\" / \"What were we working on?\" Orient /ctx-status \"How's our context looking?\" Pick /ctx-next \"What should we work on?\" / \"Let's do the caching task\" Work (none) \"Only change files in internal/cache/\" Commit /ctx-commit \"Commit this\" / \"Ship it\" Reflect /ctx-reflect \"What did we learn?\" / (agent offers at milestones) Wrap up /ctx-wrap-up (use the slash command for completeness) The agent understands both columns.
In practice, most sessions use a mix:
- Explicit Commands when you want precision;
- Natural Language when you want flow and agentic autonomy.
The agent will also initiate steps on its own (particularly \"Reflect\") when it recognizes a milestone.
Short sessions (quick bugfix) might only use: Load, Work, Commit.
Long sessions should Reflect after each major milestone and persist learnings and decisions before ending.
","path":["Recipes","Sessions","The Complete Session"],"tags":[]},{"location":"recipes/session-lifecycle/#tips","level":2,"title":"Tips","text":"Persist early if context is running low. A hook monitors context capacity and notifies you when it gets high, but do not wait for the notification. If you have been working for a while and have unpersisted learnings, persist proactively.
Browse previous sessions by topic. If you need context from a prior session, ctx journal source --show auth will match by keyword. You do not need to remember the exact date or slug.
Reflection is optional but valuable. You can skip /ctx-reflect for small changes, but always persist learnings and decisions before ending a session where you did meaningful work. These are what the next session loads.
Let the hook handle context loading. The PreToolUse hook runs ctx agent automatically with a cooldown, so context loads on first tool use without you asking. The /ctx-remember prompt at session start is for your benefit (to get a readback), not because the assistant needs it.
The agent is a proactive partner, not a passive tool. A ctx-aware agent follows the Agent Playbook: it watches for milestones (completed tasks, design decisions, discovered gotchas) and offers to persist them without being asked. If you finish a tricky debugging session, it may say \"That root cause is worth saving as a learning. Want me to record it?\" before you think to ask. This is by design.

This recipe walks through writing a steering file from scratch, validating which prompts will trigger it, and syncing it out to your configured AI tools.
Before You Start
If you're unsure whether a rule belongs in steering/, DECISIONS.md, or CONVENTIONS.md, read the \"Steering vs decisions vs conventions\" admonition on the ctx steering reference page. The short version: if the rule is \"the AI should always do X when asked about Y,\" that's steering. Otherwise it's probably a decision or convention.
","path":["Recipes","Agents and Automation","Writing Steering Files"],"tags":[]},{"location":"recipes/steering/#start-here-customize-the-foundation-files","level":2,"title":"Start Here: Customize the Foundation Files","text":"ctx init scaffolds four foundation steering files for you the first time you initialize a project:
File Purpose .context/steering/product.md Product context, goals, target users .context/steering/tech.md Tech stack, constraints, key dependencies .context/steering/structure.md Directory layout, naming conventions .context/steering/workflow.md Branch strategy, commit rules, pre-commit Each file opens with an inline HTML comment that explains the three inclusion modes, what priority means, and the tools scope. The comment is invisible in rendered markdown but visible when you edit the file. Delete it once the file is yours.
All four default to inclusion: always and priority: 10, so they fire on every AI tool call until you customize them. If you're reading this recipe and haven't touched them yet, open each one now and replace the placeholder bullet list with actual rules for your project. That's the highest-leverage five minutes you can spend in a new ctx setup.
What to fill in, by file:
product.md: The elevator pitch plus hard scope:
- One-sentence product description.
- Primary users and their top job-to-be-done.
- Two or three \"this is explicitly out of scope\" items so the AI doesn't wander.
tech.md: Technology and constraints:
- Languages and versions (
Go 1.22, Node 20, etc.). - Frameworks and key libraries.
- Runtime and deployment target.
- Hard constraints: \"no CGO\", \"no network at test time\", \"no external DB for unit tests\". These are the things that burn agents when they don't know them.
structure.md: Layout and naming:
- Top-level directories and their purpose.
- Where new files should go (and where they should NOT).
- Naming conventions for packages, files, types.
workflow.md: Process rules:
- Branch strategy (main-only, trunk-based, feature branches).
- Commit message format, signed-off-by requirement.
- Pre-commit and pre-push checks.
- Review expectations.
After editing, the next AI tool call in Claude Code will pick up the new rules automatically via the plugin's PreToolUse hook, with no sync step and no restart. Other tools (Cursor, Cline, Kiro) need ctx steering sync to export into their native format.
Prefer a Bare .context/steering/ Directory?
Re-run ctx init --no-steering-init and delete the scaffolded files. ctx init leaves existing files alone, so the flag is only needed if you want to opt out of the initial scaffold.

You want the AI to flag this concern automatically whenever it's asked to write an HTTP handler, without you having to remind it every session.
Claude Code Users: Pick always, Not auto
This walkthrough uses inclusion: auto because the scenario is a scoped rule that matches a specific kind of prompt. That works natively on Cursor, Cline, and Kiro (they resolve the description keyword match themselves).
On Claude Code, auto does not fire through the plugin's PreToolUse hook. The hook passes an empty prompt to ctx agent, so only always files match. Claude can still reach an auto file by calling the ctx_steering_get MCP tool, but that requires Claude to decide to call it; there's no automatic injection.
If Claude Code is your tool, set inclusion: always in Step 2 instead of auto. The rule will fire on every tool call regardless of topic. You may want to narrow the rule body so the extra tokens per turn aren't wasted on unrelated work.
See the ctx steering reference \"Prefer inclusion: always for Claude Code\" section for the full trade-off.

Instead, steering reaches these tools through two non-sync channels:
-
PreToolUse hook (automatic). The ctx setup claude-code plugin installs a hook that runs ctx agent --budget 8000 before each tool call. ctx agent loads your steering files, filters them against the active prompt, and includes matching bodies as Tier 6 of the context packet. The packet gets injected into Claude's context automatically.
-
ctx_steering_get MCP tool (on-demand). Claude can call this MCP tool mid-task to fetch matching steering files for a specific prompt. Automatic activation comes from Claude's judgment, not a hook.
Both channels activate when you run:
ctx setup claude-code --write\n
That installs the plugin, wires the hook, and registers the MCP server. After that, steering files you edit are picked up on the next tool call, with no sync step needed.
Running ctx steering sync with Claude Code
It won't error; it will simply report that Claude and Codex aren't sync targets and skip them. If Claude Code is your only tool, you never need to run sync. If you use both Claude Code and (say) Cursor, run sync to keep Cursor up to date; the Claude pipeline takes care of itself via the hook.

If nothing happens, the fix depends on which path you're on:
Path A (Cursor/Cline/Kiro):
- Re-run
ctx steering preview with the literal prompt to confirm the match. - Run
ctx steering list and verify inclusion is auto, not manual. - Check the tool's own config directory (e.g.
.cursor/rules/); the file should be there after ctx steering sync.
Path B (Claude Code):
- Re-run
ctx steering preview with the literal prompt to confirm the match. - Verify the plugin is installed:
cat .claude/hooks.json should include ctx agent --budget 8000 under PreToolUse. If not, re-run ctx setup claude-code --write. - Run
ctx agent --budget 8000 manually and grep the output for your rule body. If it's there, the data is fine; if it's missing, the inclusion mode or description is at fault. - As a last resort, ask Claude directly: \"Call the
ctx_steering_get MCP tool with my prompt and show me the result.\" If the MCP tool returns your rule, Claude has access but isn't pulling it into the initial context packet; tighten the description keywords.

Putting decisions in steering. \"We decided to use PostgreSQL\" is a decision, not a rule for the AI to follow on every prompt. Record decisions with ctx decision add, not ctx steering add.
Committing inclusion: always without thinking. Rules marked always fire on every prompt, consuming tier-6 budget permanently. Only use always for true invariants (security, safety, licensing). Everything else should be auto or manual.

- Hooks are throttled by design: Most check hooks fire once per day or use adaptive frequency. Don't expect a notification every prompt: Silence usually means the throttle is working, not that the hook is broken.
- Daily markers live in
.context/state/: Throttle files are stored in .context/state/ alongside other project-scoped state. If you need to force a hook to re-fire during testing, delete the corresponding marker file. - The QA reminder is intentionally noisy: Unlike other hooks,
qa-reminder fires on every Edit call with no throttle. This is deliberate: The commit quality degrades when the reminder fades from salience. - Log files are safe to commit:

Prefer Skills over Raw Commands
When working with an AI agent, use /ctx-task-add instead of raw ctx task add. The agent automatically picks up session ID, branch, and commit hash from its context, so no manual flags are needed.

Tasks Are Often Created Proactively
In practice, many tasks are created proactively by the agent rather than by explicit CLI commands.
After completing a feature, the agent will often identify follow-up work: tests, docs, edge cases, error handling, and offer to add them as tasks.
You do not need to dictate ctx task add commands; the agent picks up on work context and suggests tasks naturally.

Phases provide logical groupings that preserve order and enable replay.
A task does not move between sections. It stays in its phase permanently, and status is tracked via checkboxes and inline tags.

ctx task add \"Add ctx watch XML parsing\" --priority medium --section \\\n \"Phase 2: AI Integration\" \\\n --session-id abc12345 --branch main --commit 68fbc00a\n

Be Conversational
You rarely need to run ctx task complete yourself during an interactive session.
When you say something like \"the rate limiter is done\" or \"we finished that,\" the agent marks the task complete and moves on to suggesting what is next.
The CLI commands are most useful for manual housekeeping, scripted workflows, or when you want precision.

The agent has the full conversation in context and can spot follow-ups you might miss:
You: \"Are there any tasks, learnings, or decisions worth adding\n from this session?\"\n\nAgent: \"Yes.

- Use
#in-progress sparingly. Only one or two tasks should carry this tag at a time. If everything is in-progress, nothing is. - Snapshot before, not after. The point of a snapshot is to capture the state before a change, not to celebrate what you just finished.
- Archive regularly. Once completed tasks outnumber pending ones, it is time to archive. A clean
TASKS.md helps both you and your AI assistant focus. - Never delete tasks. Mark them
[x] (completed) or [-] (skipped with a reason). Deletion breaks the audit trail. - Trust the agent's task instincts. When the agent suggests follow-up items after completing work, it is drawing on the full context of what just happened.
- Conversational prompts beat commands in interactive sessions. Saying \"what should we work on?\" is faster and more natural than running
/ctx-next. Save explicit commands for scripts, CI, and unattended runs. - Let the agent chain operations. A single statement like \"that's done, what's next?\" can trigger completion, follow-up identification, and next-task selection in one flow.
- Review proactive task suggestions before moving on. The best follow-ups come from items spotted in-context right after the work completes.

Merge hell: If you are spending more time resolving conflicts than the parallel work saved, you split wrong: Re-group by file overlap.
Context divergence: Each agent builds its own mental model. After 30 minutes of independent work, agent A might make assumptions that contradict agent B's approach. Shorter tracks with frequent merges reduce this.
Coordination theater: A lead agent spending most of its time assigning tasks, checking status, and sending messages instead of doing work. If the task list is clear enough, worktrees with no communication are cheaper.
Re-reading overhead: Every agent reads .context/ on startup. A team of 4 agents each reading 4000 tokens of context = 16000 tokens before anyone does any work. For small tasks, that overhead dominates.

- Worktrees > teams for most parallelism needs: If agents don't need to talk to each other during execution, worktrees give you parallelism with zero coordination overhead.
- Use
ctx as the shared brain: Whether it's one agent or four, the .context/ directory is the single source of truth. Decisions go in DECISIONS.md, not in chat messages between agents. - Merge early, merge often: Long-lived parallel branches diverge. Merge a track as soon as it's done rather than waiting for all tracks to finish.
TASKS.md conflicts are normal: Multiple agents completing different tasks will conflict on merge. The resolution is always additive: accept all [x] completions from both sides.

init, add, agent, status, drift, load, sync, compact, task, decision, learning, and their siblings) is a single Go binary with no required runtime dependencies. Optional integrations (ctx trace (needs git), ctx serve (needs zensical), the ctx Hub (needs a running hub), Claude Code plugin (needs claude)) are opt-in and each declares its dependency explicitly. - CLI-driven: every feature is reachable from the command line and scriptable.

As in many ctx features, the ctx scratchpad can also be used with natural langauge. You don't have to memorize the CLI commands.
CLI gives you \"precision\", whereas natural language gives you flow.
The /ctx-pad skill maps natural language to ctx pad commands. You don't need to remember the syntax:
You say What happens \"jot down: check DNS after deploy\" ctx pad add \"check DNS after deploy\" \"show my scratchpad\" ctx pad \"delete the third entry\" ctx pad rm 3 \"update entry 2 to include the new endpoint\" ctx pad edit 2 \"...\" \"move entry 4 to the top\" ctx pad mv 4 1 \"import my notes from notes.txt\" ctx pad import notes.txt \"export all blobs to ./backup\" ctx pad export ./backup \"merge the scratchpad from the worktree\" ctx pad merge worktree/.context/scratchpad.enc The skill handles the translation.

For Claude Code, ctx init writes both an allowlist and an explicit deny list into .claude/settings.local.json. The golden images live in internal/assets/permissions/:
Allowlist (allow.txt): only these tools run without confirmation:
Bash(ctx:*)\nSkill(ctx-convention-add)\nSkill(ctx-decision-add)\n... # all bundled ctx-* skills\n
Deny list (deny.txt): these are blocked even if the agent requests them:
# Dangerous operations\nBash(sudo *)\nBash(git push *)\nBash(git push)\nBash(rm -rf /*)\nBash(rm -rf ~*)\nBash(curl *)\nBash(wget *)\nBash(chmod 777 *)\n\n# Sensitive file reads\nRead(**/.env)\nRead(**/.env.*)\nRead(**/*credentials*)\nRead(**/*secret*)\nRead(**/*.pem)\nRead(**/*.key)\n\n# Sensitive file edits\nEdit(**/.env)\nEdit(**/.env.*)\n
What it catches: The agent cannot run commands outside the allowlist, and the deny list blocks dangerous operations even if a future allowlist change were to widen access. If rm, curl, sudo, or docker are not allowed and sudo/curl/wget are explicitly denied, the agent cannot invoke them regardless of what any prompt says.
What it misses: The agent can modify the allowlist itself. In an autonomous loop, if the agent writes to .claude/settings.local.json, and the next iteration loads the modified config, then the protection is effectively lost. The application enforces the rules, but the application reads the rules from files the agent can write.

","path":["The Thesis"],"tags":[]},{"location":"thesis/#abstract","level":3,"title":"Abstract","text":"As AI tools evolve from code-completion utilities into reasoning collaborators, the knowledge that governs their behavior becomes as important as the code they produce; yet, that knowledge is routinely discarded at the end of every session.
AI-assisted development systems assemble context at prompt time using heuristic retrieval from mutable sources: recent files, semantic search results, session history. These approaches optimize relevance at the moment of generation but do not persist the cognitive state that produced decisions. Reasoning is not reproducible, intent is lost across sessions, and teams cannot audit the knowledge that constrains automated behavior.
This paper argues that context should be treated as deterministic, version-controlled state rather than as a transient query result. We ground this argument in three sources of evidence: a landscape analysis of 17 systems spanning AI coding assistants, agent frameworks, and knowledge stores; a taxonomy of five primitive categories that reveals irrecoverable architectural trade-offs; and an experience report from ctx, a persistence layer for AI-assisted development, which developed itself using its own persistence model across 389 sessions over 33 days. We define a three-tier model for cognitive state: authoritative knowledge, delivery views, and ephemeral state. Then we present six design invariants empirically validated by 56 independent rejection decisions observed across the analyzed landscape. We show that context determinism applies to assembly, not to model output, and that the curation cost this model requires is offset by compounding returns in reproducibility, auditability, and team cognition.
","path":["The Thesis"],"tags":[]},{"location":"thesis/#1-introduction","level":2,"title":"1. Introduction","text":"The introduction of large language models into software development has shifted the primary interface from code execution to interactive reasoning. In this environment, the correctness of an output depends not only on source code but on the context supplied to the model: the conventions, decisions, architectural constraints, and domain knowledge that bound the space of acceptable responses.
Current systems treat context as a query result assembled at the moment of interaction. A developer begins a session; the tool retrieves what it estimates to be relevant from chat history, recent files, and vector stores; the model generates output conditioned on this transient assembly; the session ends, and the context evaporates. The next session begins the cycle again.
This model has improved substantially over the past year. CLAUDE.md files, Cursor rules, Copilot's memory system, and tools such as Mem0, Letta, and Kindex each address aspects of the persistence problem. Yet across 17 systems we analyzed spanning AI coding assistants, agent frameworks, autonomous coding agents, and purpose-built knowledge stores, no system provides all five of the following properties simultaneously: deterministic context assembly, human-readable file-based persistence, token-budgeted delivery, a single-binary core with zero required runtime dependencies for the persistence path, and local-first operation.
This paper does not propose a universal replacement for retrieval-centric workflows. It defines a persistence layer (embodied in ctx (https://ctx.ist)) whose advantages emerge under specific operational conditions: when reproducibility is a requirement, when knowledge must outlive sessions and individuals, when teams require shared cognitive authority, or when offline operation is necessary.
The trade-offs (manual curation cost, reduced automatic recall, coarser granularity) are intentional and mirror the trade-offs accepted by systems that favor reproducibility over convenience, such as reproducible builds and immutable infrastructure 1 6.
The contribution is threefold: a three-tier model for cognitive state that resolves the ambiguity between authoritative knowledge and ephemeral session artifacts; six design invariants empirically grounded in a cross-system landscape analysis; and an experience report demonstrating that the model produces compounding returns when applied to its own development.

A developer who asks \"What is our authentication strategy?\" on Tuesday may receive a different context window than the same question on Thursday: Not because the strategy changed, but because the retrieval heuristic surfaced different fragments.
Reproducibility (the ability to reconstruct the exact inputs that produced a given output) is a foundational property of reliable systems. Its loss in AI-assisted development mirrors the historical evolution from ad-hoc builds to deterministic build systems 1 2. The build community learned that when outputs depend on implicit state (environment variables, system clocks, network-fetched dependencies), debugging becomes archaeology. The same principle applies when AI outputs depend on non-deterministic context retrieval.

When a vector store determines that a code snippet is \"similar\" to the current query, the ranking function is opaque: the developer cannot inspect why that snippet was chosen, whether a more relevant artifact was excluded, or whether the ranking will remain stable. This prevents deterministic debugging, policy auditing, and causal attribution (properties that information retrieval theory identifies as fundamental trade-offs of probabilistic ranking) 3.
In practice, this opacity manifests as a compliance ceiling. In our experience developing a context management system (detailed in Section 7), soft instructions (directives that ask an AI agent to read specific files or follow specific procedures) achieve approximately 75-85% compliance. The remaining 15-25% represents cases where the agent exercises judgment about whether the instruction applies, effectively applying a second ranking function on top of the explicit directive. When 100% compliance is required, instruction is insufficient; the content must be injected directly, removing the agent's option to skip it.

Cognitive State: A Three-Tier Model","text":"","path":["The Thesis"],"tags":[]},{"location":"thesis/#31-definitions","level":3,"title":"3.1 Definitions","text":"We define cognitive state as the authoritative, persistent representation of the knowledge required for correct decision-making within a project. It is human-authored or human-ratified, versioned, inspectable, and reproducible. It is distinct from logs, transcripts, retrieval results, and model-generated summaries.
Previous formulations of this idea have treated cognitive state as a monolithic concept. In practice, a three-tier model better captures the operational reality:
Tier 1: Authoritative State: The canonical knowledge that the system treats as ground truth. In a concrete implementation, this corresponds to a set of human-curated files with defined schemas: a constitution (inviolable rules), conventions (code patterns), an architecture document (system structure), decision records (choices with rationale), learnings (captured experience), a task list (current work), a glossary (domain terminology), and an agent playbook (operating instructions). Each file has a single purpose, a defined lifecycle, and a distinct update frequency. Authoritative state is version-controlled alongside code and reviewed through the same mechanisms (diffs, pull requests, blame annotations).
Tier 2: Delivery Views: Derived representations of authoritative state, assembled for consumption by a model. A delivery view is produced by a deterministic assembly function that takes the authoritative state, a token budget, and an inclusion policy as inputs and produces a context window as output. The same authoritative state, budget, and policy must always produce the same delivery view. Delivery views are ephemeral (they exist only for the duration of a session), but their construction is reproducible.
Tier 3: Ephemeral State: Session transcripts, scratchpad notes, draft journal entries, and other artifacts that exist during or immediately after a session but are not authoritative. Ephemeral state is the raw material from which authoritative state may be extracted through human review, but it is never consumed directly by the assembly function.
This three-tier model resolves confusion present in earlier formulations: the claim that AI output is a deterministic function of the repository state. The corrected claim is that context selection is deterministic (the delivery view is a function of authoritative state), but model output remains stochastic, conditioned on the deterministic context. Formally:
delivery_view = assemble(authoritative_state, budget, policy)\noutput = model(delivery_view) # stochastic\n
The persistence layer's contribution is making assemble reproducible, not making model deterministic.

Separation enables progressive disclosure: the minimum context that matters for the current moment, with the option to load more when needed. A normal session loads the constitution, tasks, and conventions; a deep investigation loads decision history and journal entries from specific dates.
The budget mechanism is the constraint that makes separation valuable. Without a budget, the default behavior is to load everything, which destroys the attention density that makes loaded context useful. With a budget, the assembly function must prioritize ruthlessly: constitution first (always full), then tasks and conventions (budget-capped), then decisions and learnings (scored by recency). Entries that do not fit receive title-only summaries rather than being silently dropped (an application of the \"tell me what you don't know\" pattern identified independently by four systems in our landscape analysis).

The resulting set spans six categories: AI coding assistants (Continue, Sourcegraph/Cody, Aider, Claude Code), AI agent frameworks (CrewAI, AutoGen, LangGraph, LlamaIndex, Letta/MemGPT), autonomous coding agents (OpenHands, Sweep), session provenance tools (Entire), data versioning systems (Dolt, Pachyderm), pipeline/build systems (Dagger), and purpose-built knowledge stores (QubicDB, Kindex). Each system was analyzed from its source code and documentation, producing 34 individual analysis artifacts (an architectural profile and a set of insights per system) that yielded 87 adopt/adapt recommendations, 56 explicit rejection decisions, and 52 watch items.

Our analysis of 17 systems reveals five categories of primitives, each making irrecoverable trade-offs:
Group A: Document/File Primitives: Human-readable documents as the primary unit. Documents are authored by humans, version-controlled in git, and consumed by AI tools. The invariant of this group is that the primitive is always human-readable and version-controllable with standard tools. Three systems participate in this pattern: the system described in this paper as a pure expression, and Continue (via its rules directory) and Claude Code (via CLAUDE.md files) as partial participants: both use document-based context as an input but organize around different core primitives.
Group B: Embedded Record Primitives: Vector-embedded records stored with numerical embeddings for similarity search, metadata for filtering, and scoring mechanisms for ranking. Five systems use this approach (LlamaIndex, CrewAI, Letta/MemGPT, QubicDB, Kindex). The invariant is that the primitive requires an embedding model or vector database for core operations: a dependency that precludes offline and air-gapped use.
Group C: State Snapshot Primitives: Point-in-time captures of the complete system state. The invariant is that any past state can be reconstructed at any historical point. Three systems use this approach (LangGraph, Entire, Dolt).
Group D: Event/Message Primitives: Sequential events or messages forming an append-only log with causal relationships. Four systems use this approach (OpenHands, AutoGen, Claude Code, Sweep). The invariant is temporal ordering and append-only semantics.
Group E: Construction/Derivation Primitives: Derived or constructed values that encode how they were produced. The invariant is that the primitive is a function of its inputs; re-executing the same inputs produces the same primitive. Three systems use this approach (Dagger, Pachyderm, Aider).

The choice between primitive categories is not a matter of capability but of which properties are considered invariant.
","path":["The Thesis"],"tags":[]},{"location":"thesis/#53-convergent-patterns","level":3,"title":"5.3 Convergent Patterns","text":"Across the 17 analyzed systems, six design patterns were independently discovered. These convergent patterns carry extra validation weight because they emerged from different problem spaces:
Pattern 1: \"Tell me what you don't know\": When context is incomplete, explicitly communicate to the model what information is missing and what confidence level the provided context represents. Four systems independently converged on this pattern: inserting skip markers, tracking evidence gaps, annotating provenance, or naming output quality tiers.
Pattern 2: \"Freshness matters\": Information relevance decreases over time. Three systems independently chose exponential decay with different half-lives (30 days, 90 days, and LRU ordering). Static priority ordering with no time dimension leaves relevant recent knowledge at the same priority as stale entries. This pattern is in productive tension with the persistence model's emphasis on determinism: the claim is not that time-dependence is irrelevant, but that it belongs in the curation step (a human deciding to consolidate or archive stale entries) rather than in the assembly function (an algorithm silently down-ranking entries based on age).
Pattern 3: \"Content-address everything\": Compute a hash of content at creation time for deduplication, cache invalidation, integrity verification, and change detection. Five systems independently implement content hashing, each discovering it solves different problems 5.
Pattern 4: \"Structured beats freeform\": When capturing knowledge or session state, a structured schema with required fields produces more useful data than freeform text. Four systems evolved from freeform summaries to typed schemas: one moving from LLM-generated prose to a structured condenser with explicit fields for completed tasks, pending tasks, and files modified.
Pattern 5: \"Protocol convergence\": The Model Context Protocol (MCP) is emerging as a standard tool integration layer. Nine of 17 systems support it, spanning every category in the analysis. MCP's significance for the persistence model is that it provides a transport mechanism for context delivery without dictating how context is stored or assembled. This makes the approach compatible with both retrieval-centric and persistence-centric architectures.
Pattern 6: \"Human-in-the-loop for memory\": Critical memory decisions should involve human judgment. Fully automated memory management produces lower-quality persistent context than human-reviewed systems. Four systems independently converged on variants of this pattern: ceremony-based consolidation, interrupt/resume for human input, confirmation mode for high-risk actions, and separated \"think fast\" vs. \"think slow\" processing paths.
Pattern 6 directly validates the ceremony model described in this paper. The persistence layer requires human curation not because automation is impossible, but because the quality of persistent knowledge degrades when the curation step is removed. The improvement opportunity is to make curation easier, not to automate it away.

Reversal 1: The two-tier persistence model: The original design included a middle storage tier for session copies. After 21 days of development, the middle tier was identified as a dead-end write sink (described in Section 6). The decision record captured the full context, and the removal was executed cleanly: 15 source files, a shell hook, and 45 documentation references. The pattern of a \"dead-end write sink\" was subsequently observed in 7 of 17 systems in our landscape analysis that store raw transcripts alongside structured context.
Reversal 2: The prompt-coach hook: An early design included a hook that analyzed user prompts and offered improvement suggestions. After deployment, the hook produced zero useful tips, its output channel was invisible to users, and it accumulated orphan temporary files. The hook was removed, and the decision record captured the failure mode for future reference.
Reversal 3: The soft-instruction compliance model: The original context injection strategy relied on soft instructions: directives asking the AI agent to read specific files. After measuring compliance across multiple sessions, we found a consistent 75-85% compliance ceiling. The revised strategy injects content directly, bypassing the agent's judgment about whether to comply. The learning record captures the ceiling measurement and the rationale for the architectural change.
Each reversal was captured as a structured decision record with context, rationale, and consequences. In a retrieval-based system, these reversals would exist only in chat history, discoverable only if the retrieval function happens to surface them. In the persistence model, they are permanent, indexable artifacts that inform future decisions.

It means that any context management strategy relying on agent compliance with instructions (\"read this file,\" \"follow this convention,\" \"check this list\") has a hard ceiling on reliability.
The root cause is structural: the instruction \"don't apply judgment\" is itself evaluated by judgment. When an agent receives a directive to read a file, it first assesses whether the directive is relevant to the current task (and that assessment is the judgment the directive was trying to prevent).
The architectural response maps directly to the formal model defined in Section 3.1. Content requiring 100% compliance is included in authoritative_state and injected by the deterministic assemble function, bypassing the agent entirely. Content where 80% compliance is acceptable is delivered as instructions within the delivery view. The three-tier architecture makes this distinction explicit: authoritative state is injected; delivery views are assembled deterministically; ephemeral state is available but not pushed.

Later sessions (days 25-33) began with the agent loading curated context and immediately operating within established constraints, because the constraints were in files rather than in chat history.
This compounding effect (where each session's context curation improves all subsequent sessions) is the primary return on the curation investment. The cost is borne once (writing a decision record, capturing a learning, updating the task list); the benefit is collected on every subsequent session load.
The effect is analogous to compound interest in financial systems: the knowledge base grows not linearly with effort but with increasing marginal returns as new knowledge interacts with existing context. A learning captured on day 5 prevents a mistake on day 12, which avoids a debugging session that would have consumed a day 12 session, freeing that session for productive work that generates new learnings.

The persistence layer sits beneath retrieval and above version control. Its role is to maintain the authoritative state that retrieval systems may query but do not own.

Knowledge must outlive sessions and individuals: Projects with multi-year lifetimes accumulate architectural decisions, domain interpretations, and operational policy.

The response is not that the cost is negligible but that it is amortized. A decision record written once is loaded hundreds of times. A learning captured today prevents repeated mistakes across all future sessions. The curation cost is paid once; the benefit compounds.
The experience report provides rough order-of-magnitude numbers. Across 389 sessions over 33 days, curation activities (writing decision records, capturing learnings, updating the task list, consolidating entries) averaged approximately 3-5 minutes per session. In early sessions (days 1-7), before curated context existed, re-establishing context consumed approximately 10-15 minutes per session: re-explaining conventions, re-stating architectural constraints, re-deriving decisions that had been made but not persisted. By the final week (days 25-33), the re-explanation overhead had dropped to near zero: the agent loaded curated context and began productive work immediately.
At ~12 sessions per day, the curation cost was roughly 35-60 minutes daily. The re-explanation cost in the first week was roughly 120-180 minutes daily. By the third week, that cost had fallen to under 15 minutes daily while the curation cost remained stable.

Content-addressed context caches: Five systems in our landscape analysis independently discovered that content hashing provides cache invalidation, integrity verification, and change detection. Applying content addressing to the assembly output would enable efficient cache reuse when the authoritative state has not changed.
Conditional context inclusion: Five systems independently suggest that context entries could carry activation conditions (file patterns, task keywords, or explicit triggers) that control whether they are included in a given assembly. This would reduce the per-session budget cost of large knowledge bases without sacrificing determinism.

Conclusion","text":"AI-assisted development has treated context as a \"query result\" assembled at the moment of interaction, discarded at the session end. This paper identifies a complementary layer: the persistence of authoritative cognitive state as deterministic, version-controlled artifacts.
The contribution is grounded in three sources of evidence. A landscape analysis of 17 systems reveals five categories of primitives and shows that no existing system provides the combination of human-readability, determinism, zero dependencies, and offline capability that the persistence layer requires. Six design invariants, validated by 56 independent rejection decisions, define the constraints of the design space. An experience report over 389 sessions and 33 days demonstrates compounding returns: later sessions start faster, decisions are not re-derived, and architectural reversals are captured with full context.
The core claim is this: persistent cognitive state enables causal reasoning across time. A system built on this model can explain not only what is true, but why it became true and when it changed.
When context is the state:
- Reasoning is reproducible: the same authoritative state, budget, and policy produce the same delivery view.
- Knowledge is auditable: decisions are traceable to explicit artifacts with context, rationale, and consequences.
- Understanding compounds: each session's curation improves all subsequent sessions.
The choice between retrieval-centric workflows and a persistence layer is not a matter of capability but of time horizon. Retrieval optimizes for relevance at the moment of interaction. Persistence optimizes for the durability of understanding across the lifetime of a project.

Kindex's knowledge graph as core primitive was rejected because it requires specialized commands to inspect content that could be a text file (kin show <id> vs. cat DECISIONS.md).
Invariant 2: Zero Runtime Dependencies (13 rejections): Letta/MemGPT's PostgreSQL-backed architecture was rejected because it conflicts with local-first, no-database, single-binary operation. Pachyderm's Kubernetes-based distributed architecture was rejected as the antithesis of a single-binary design for a tool that manages text files.
Invariant 3: Deterministic Assembly (6 rejections): LlamaIndex's embedding-based retrieval as the primary selection mechanism was rejected because it destroys determinism, requires an embedding model, and removes human judgment from the selection process. QubicDB's wall-clock-dependent scoring was rejected because it directly conflicts with the \"same inputs produce same output\" property.
Invariant 4: Human Authority (6 rejections): Letta/MemGPT's agent self-modification of memory was rejected as fundamentally opposed to human-curated persistence. Claude Code's unstructured auto-memory (where the agent writes freeform notes) was rejected because structured files with defined schemas produce higher-quality persistent context than unconstrained agent output.
Invariant 5: Local-First / Air-Gap Capable (7 rejections): Sweep's cloud-dependent architecture was rejected as fundamentally incompatible with the local-first, offline-capable model. LangGraph's managed cloud deployment was rejected because cloud dependencies for core functionality violate air-gap capability.
Invariant 6: No Default Telemetry (4 rejections): Continue's telemetry-by-default (PostHog) was rejected because it contradicts the local-first, privacy-respecting trust model. CrewAI's global telemetry on import (Scarf tracking pixel) was rejected because it violates user trust and breaks air-gap capability.
The remaining 9 rejections did not map to a specific invariant but were rejected on other architectural grounds: for example, Aider's full-file-content-in-context approach (which defeats token budgeting), AutoGen's multi-agent orchestration as core primitive (scope creep), and Claude Code's 30-day transcript retention limit (institutional knowledge should have no automatic expiration).

Context Is a Record
Context is a persistent record.
By \"context\", I don't mean model memory or stored thoughts:
I mean the durable record of decisions, learnings, and intent that normally evaporates between sessions.

Autoload worked (via Claude Code's PreToolUse hook), but auto-save was missing: If the user quit, with Ctrl+C, everything since the last manual save was lost.
That session became the first real test of the system.

A comparison session on January 25th revealed the patterns:
YOLO Pattern What We Found \"TASKS.md\" scattered in 10 files Same string literal everywhere, no constants dir + \"/\" + file Should be filepath.Join() Monolithic cli_test.go (1500+ lines) Tests disconnected from implementations package initcmd in init/ folder Go's \"init\" is reserved: subtle naming collision Here is another analysis made by ctx:
● Based on my analysis, here are the key differences:\n\nYOLO Mode (Pre-040ce99)\n- Feature-first: Added slash commands, tests, templates rapidly\n- Scattered magic strings: \"TASKS.md\", \"decision\", \".context\" spread across files\n- Quick file creation: New files without organizational patterns\n- Working but inconsistent: Code functioned but lacked systematic structure\n\nHuman-Guided Mode (Post-040ce99)\n- Consolidation focus: Centralized constants in config package\n- Consistent naming: Dir, File, Filename, UpdateType prefixes\n- Self-referential constants: FileType map uses constants as keys, not literals\n- Proper path construction: filepath.Join() instead of +\"/\"+\n- Colocated tests: Tests next to implementations\n- Canonical naming: Package name = folder name\n
The fix required a human-guided refactoring session. I continued to do that before every major release, from that point on.
We introduced internal/config/config.go with semantic prefixes:
const (\n DirContext = \".context\"\n DirArchive = \"archive\"\n DirSessions = \"sessions\"\n FilenameTask = \"TASKS.md\"\n UpdateTypeTask = \"task\"\n)\n
What I begrudgingly learned was: YOLO mode is effective for velocity but accumulates debt.

They are not part of the source code due to security, privacy, and size concerns.
Middle Ground: The Scratchpad
For sensitive notes that do need to travel with the project, ctx pad stores encrypted one-liners in git, and ctx pad add \"label\" --file PATH can ingest small files.
See Scratchpad for details.
However, they are invaluable for the project's progress.
Each session file is a timestamped Markdown with:
- Summary of what has been accomplished;
- Key decisions made;
- Learnings discovered;
- Tasks for the next session;
- Technical context (platform, versions).
These files are not autoloaded (that would bust the token budget).
They are what I see as the \"archaeological record\" of ctx:
When the AI needs deeper information about why something was done, it digs into the sessions.
Auto-generated session files used a naming convention:
2026-01-23-115432-session-prompt_input_exit-summary.md\n2026-01-25-220244-manual-save.md\n2026-01-27-052107-session-other-summary.md\n
Update
The session feature described here is historical.
In current releases, ctx uses a journal instead: the enrichment process generates meaningful slugs from context automatically, so there is no need to manually save sessions.
The SessionEnd hook captured transcripts automatically. Even Ctrl+C was caught.

When the AI remembers decisions, it doesn't repeat mistakes.
When the AI knows your conventions, it follows them.
ctx makes the AI a better collaborator because it's not starting from zero.
2. Two-tier persistence works
Curated context (DECISIONS.md, LEARNINGS.md, TASKS.md) is for quick reload.
Full session dumps are for archaeology.
It's a futile effort to try to fit everything in the token budget.
Persist more, load less.
3. YOLO mode has its place
For rapid prototyping, letting the AI run free is effective.
But I had to schedule consolidation sessions.
Technical debt accumulates silently.
4. The constitution should be small
Only truly inviolable rules go in CONSTITUTION.md. Everything else is a convention.
If you put too much in the constitution, it will get ignored.
5. Verification is non-negotiable
\"All tasks complete\" means nothing if you haven't run the tests.
Integration tests that invoke the actual binary caught bugs that the unit tests missed.
6. Session files are underrated
The ability to grep through 40 session files and find exactly when and why a decision was made helped me a lot.
It's not about loading them into context: It is about having them when you need them.

The AI now remembers decisions, learnings, and tasks across sessions.
But a new problem emerged, which I can sum up as:
\"I (the human) am not AI.\"
Frankly, I couldn't remember what the AI remembered.
Let alone, I cannot remember what I ate for breakfast!
In the course of days, I realized session transcripts piled up in .context/sessions/; I was grepping, JSONL files with thousands of lines... Raw tool calls, assistant responses, user messages...
...all interleaved.
Valuable context was effectively buried in machine-readable noise.
I found myself grepping through files to answer questions like:
- \"When did we decide to use constants instead of literals?\"
- \"What was the session where we fixed the hook regex?\"
- \"How did the
embed.go split actually happen?\"
Fate Is Whimsical
The irony was painful:
I built a tool to prevent AI amnesia, but I was suffering from human amnesia about what happened in AI sessions.
This was the moment ctx stopped being just an AI tool and started needing to support the human on the other side of the loop.

Structure stopped being optional.
v0.2.0 enforces structure:
ctx add decision \"Use PostgreSQL\" \\\n --context \"Need a reliable database for user data\" \\\n --rationale \"ACID compliance, team familiarity, strong ecosystem\" \\\n --consequence \"Need to set up connection pooling, team training\"\n

Earlier decisions are more likely to be relevant, and they are more likely to have more emphasis on the project. So it follows that they should be read first.
But back to AI:
When the AI reads a file, it reads from the top (and seldom from the bottom).
If the token budget is tight, old content gets truncated. As in any good engineering practice, it's always about the tradeoffs.
Reverse order ensures the most recent (and most relevant) context is always loaded first.

Every token you send to an AI model consumes a finite resource I call the attention budget.
Attention budget is real.
The model doesn't just read tokens; it forms relationships between them:
For n tokens, that's roughly n^2 relationships.
Double the context, and the computation quadruples.
But the more important constraint isn't cost: It's attention density.
Attention Density
Attention density is how much focus each token receives relative to all other tokens in the context window.
As context grows, attention density drops: Each token gets a smaller slice of the model's focus. Nothing is ignored; but everything becomes blurrier.
Think of it like a flashlight: In a small room, it illuminates everything clearly. In a warehouse, it becomes a dim glow that barely reaches the corners.
This is why ctx agent has an explicit --budget flag:
ctx agent --budget 4000 # Force prioritization\nctx agent --budget 8000 # More context, lower attention density\n
The budget isn't just about cost: It's about preserving signal.

Research shows that transformer-based models tend to attend more strongly to the beginning and end of a context window than to its middle (a phenomenon often called \"lost in the middle\")1.
Positional anchors matter, and the middle has fewer of them.
In practice, this means that information placed \"somewhere in the middle\" is statistically less salient, even if it's important.
ctx orders context files by logical progression: What the agent needs to know before it can understand the next thing:
CONSTITUTION.md: Constraints before action. TASKS.md: Focus before patterns. CONVENTIONS.md: How to write before where to write. ARCHITECTURE.md: Structure before history. DECISIONS.md: Past choices before gotchas. LEARNINGS.md: Lessons before terminology. GLOSSARY.md: Reference material. AGENT_PLAYBOOK.md: Meta instructions last.
This ordering is about logical dependencies, not attention engineering. But it happens to be attention-friendly too:
The files that matter most (CONSTITUTION, TASKS, CONVENTIONS) land at the beginning of the context window, where attention is strongest.
Reference material like GLOSSARY sits in the middle, where lower salience is acceptable.
And AGENT_PLAYBOOK, the operating manual for the context system itself, sits at the end, also outside the \"lost in the middle\" zone. The agent reads what to work with before learning how the system works.
This is ctx's first primitive: hierarchical importance.
Not all context is equal.

Have You Ever Written a Skill That Made Your AI Worse?
You craft detailed instructions. You add examples. You build elaborate guardrails...
...and the AI starts behaving more erratically, not less.
AI coding agents like Claude Code ship with carefully designed system prompts. These prompts encode default behaviors that have been tested and refined at scale.
When you write custom skills that conflict with those defaults, the AI has to reconcile contradictory instructions:
The result is often nondeterministic and unpredictable.
Platform?
By platform, I mean the system prompt and runtime policies shipped with the agent: the defaults that already encode judgment, safety, and scope control.
This post catalogues the conflict patterns I have encountered while building ctx, and offers guidance on what skills should (and, more importantly, should not) do.

You Are the Guest, Not the Host
Treat the system prompt like a kernel scheduler.
You don't re-implement it in user space:
you configure around it.
A skill that says \"always add comprehensive error handling\" fights the built-in \"only validate at system boundaries.\"
A skill that says \"add docstrings to every function\" fights \"don't add docstrings to unchanged code.\"

- Tables that label hesitation as \"excuses\" or \"rationalization\"
<EXTREMELY-IMPORTANT> urgency tags - Threats: \"If you don't do this, you'll be replaced\"
This is harmful, and dangerous:
AI agents are designed to exercise judgment:
The system prompt explicitly says to:
- consider blast radius;
- check with the user before risky actions;
- and match scope to what was requested.
Once judgment is suppressed, every other safeguard becomes optional.
Example (bad):
## Rationalization Prevention\n\n| Excuse | Reality |\n|------------------------|----------------------------|\n| \"*This seems overkill*\"| If a skill exists, use it |\n| \"*I need context*\" | Skills come BEFORE context |\n| \"*Just this once*\" | No exceptions |\n

The attack vector structurally identical to prompt injection.
It teaches the AI that its own judgment is wrong.
It weakens or disables safeguard mechanisms, and it is dangerous.

When thresholds or wording differ, the AI has to choose.

Your project is unique: So should your skills be.
Here is the part no template can provide:
ctx's actual drift patterns.
Before evaluating the skill, I did archaeology. I read through:
- Blog posts from previous refactoring sessions;
- The project's learnings and decisions files;
- Session journals spanning weeks of development.
What I found was specific:
Drift Pattern Where How Often Is/Has/Can predicate prefixes 5+ exported methods Every YOLO sprint Magic strings instead of constants 7+ files Gradual accumulation Hardcoded file permissions (0755) 80+ instances Since day one Lines exceeding 80 characters Especially test files Every session Duplicate code blocks Test and non-test code When agent is task-focused The generic skill had no check for any of these. It couldn't; because these patterns are specific to this project's conventions, its Go codebase, and its development rhythm.

- TODO/FIXME: constitution violation (move to TASKS.md)
- Path construction: string concatenation instead of

Dead exports: unused public API

Every check has a detection command.
- Every check maps to a specific convention or constitution rule.
- Every check was discovered through actual project history; not invented from a template.

You can't import expertise. You have to grow it from your project's own history.
A skill that says \"check for code duplication\" is not expertise: It's a category.
Expertise is knowing, in the heart of your hearts, that this project accumulates Is* predicate violations during velocity sprints, that this codebase has 80 hardcoded permission literals because nobody made a constant, that this team's test files drift wide because the agent prioritizes getting the task done over keeping the code in shape.
The Parallel to the 3:1 Ratio
In Refactoring with Intent, I described the 3:1 ratio: three YOLO sessions followed by one consolidation session.
The same ratio applies to skills: you need experience in the project before you can write effective guidance for the project.
Importing a skill on day one is like scheduling a consolidation session before you've written any code.

-
List your actual drift: Read your own session history, learnings, and post-mortems. What breaks in practice? Does the skill check for those things?

Measure by deletion: After adaptation, how much of the original survives? If you're keeping less than 30%, you would have been faster writing from scratch.

Frameworks travel. Expertise doesn't.

Then I rewrote all of them in a single session. This is what I learned.

Seven lines of body. A vague description. No guidance on when to use it, when not to, what the command actually accepts, or how to tell if it worked.
As a result, the agent would either never trigger the skill (the description was too vague), or trigger it and produce shallow output (no examples to calibrate quality).
A skill without boundaries is just a suggestion.
More precisely: the most effective boundary I found was a quality gate that runs before execution, not during it.

- Without this gate, the agent would execute immediately on trigger.
- With it, the agent pauses to verify preconditions.
The difference is dramatic: instead of shallow, reflexive execution, you get considered output.

Some examples of negative triggers that made a real difference:
Skill Negative Trigger ctx-reflect \"When the user is in flow; do not interrupt\" ctx-save \"After trivial changes; a typo does not need a snapshot\" prompt-audit \"Unsolicited; only when the user invokes it\" qa \"Mid-development when code is intentionally incomplete\" These are not just nice-to-have.

Good/bad example pairs avoid guessing:

Skills Are for the Agents
Every sentence in a skill should be actionable by the agent.
If the guidance requires human judgment or human tools, it belongs in documentation, not in a skill.
The corollary: command references must be exact.
A skill that says \"save it somewhere\" is useless.
A skill that says ctx add learning --context \"...\" --lesson \"...\" --application \"...\" is actionable.
The agent can pattern-match and fill in the blanks.

ctx deploys skills through templates (via ctx init). Every skill exists in two places: the live version (.claude/skills/) and the template (internal/assets/claude/skills/).
They must match.
During the rewrite, every skill update required editing both files and running diff to verify. This sounds trivial, but across 16 template-backed skills, it was the most error-prone part of the process.
Template drift is dangerous because it creates false confidence: the agent appears to follow rules that no longer exist.

- read-only agents,
- structured output format,
- concrete file references,
- ranked recommendations.
It ran for about 20 minutes and produced eight Markdown reports.
The reports were good: Not perfect, but actionable.
What mattered was not the speed. It was that the work could be explored without committing to any single outcome.
They surfaced a stale doc.go referencing a subcommand that was never built.
They found 311 build-then-test sequences I could reduce to a single make check.
They identified that 42% of my sessions start with \"do you remember?\", which is a lot of repetition for something a skill could handle.
I had findings. I had recommendations. I had the instinct to automate.

That last row matters. Skills consume the attention budget every time the platform considers activating them.
A skill that triggers quarterly but gets evaluated on every prompt is pure waste: attention spent on something that will say \"When NOT to Use: now\" 99% of the time.
Runbooks have zero attention cost. They sit in a Markdown file until a human decides to use them.
- The human provides the judgment about timing.
- The prompt provides the structure.
The Attention Budget Applies to Skills Too
Every skill in .claude/skills/ is a standing claim on the context window. The platform evaluates skill descriptions against every user prompt to decide whether to activate.
Twenty focused skills are fine. Thirty might be fine. But each one added reduces the headroom available for actual work.
Recipes are skills that opted out of the attention tax.

Avoid Generic Advice
Suggestions that are not grounded in a project's actual structure, history, and workflows are worse than useless:
They create false confidence.
If an analysis cannot point to concrete files, commits, sessions, or patterns, it should say \"no finding\" instead of inventing best practices.

The urge to automate is not the same as the need to automate:
- The 3:1 ratio taught me that not every session should be a YOLO sprint.
- The E/A/R framework taught me that not every template is worth importing. Now the audit is teaching me that not every useful prompt is worth institutionalizing.
The common thread is restraint:
- Knowing when to stop.
- Recognizing that the cost of automation is not just the effort to build it.
The cost is the ongoing attention tax of maintaining it, the context it consumes, and the false confidence it creates when it drifts.
An entry in hack/runbooks/codebase-audit.md is honest about what it is:
A prompt I wrote once, improved once, and will adapt again next time:
- It does not pretend to be a reliable contract.
- It does not claim attention budget.
- It does not drift silently.
The Automation Instinct
When you find a useful prompt, the instinct is to institutionalize it. Resist.

The best automation decision is sometimes not to automate.
A runbook in a Markdown file costs nothing until you use it.
A skill costs attention on every prompt, whether it fires or not.

It follows instructions from context, and context can be poisoned.
I was writing the autonomous loops recipe for ctx: the guide for running an AI agent in a loop overnight, unattended, working through tasks while you sleep. The original draft had a tip at the bottom:
Use CONSTITUTION.md for guardrails. Tell the agent \"never delete tests\" and it usually won't.

An attacker who can inject content into any of those sources can redirect the agent's behavior. And \"attacker\" does not always mean a person with malicious intent. It can be:
Vector Example A dependency A malicious npm package with instructions in its README or error output A URL Documentation page with embedded adversarial instructions A project file A contributor who adds instructions to CLAUDE.md or .cursorrules The agent itself In an autonomous loop, the agent modifies its own config between iterations A command output An error message containing instructions the agent interprets and follows That last vector is the one that kept me up at night (literally!):
In an autonomous loop, the agent modifies files as part of its job.
If it modifies its own configuration files, the next iteration loads the modified config.
- No human reviews it.
- No diff is shown.

I learned this building ctx: The agent failures I have spent the most time debugging were never about the model's architecture.
They were about:
-
Misplaced trust: The model was confident. The output was wrong. Knowing when confidence and correctness diverge is not something you learn from a textbook. You learn it from watching patterns across hundreds of sessions.
-
Distribution shift: The model performed well on common patterns and fell apart on edge cases specific to this project. Recognizing that shift before it compounds requires understanding why generalization has limits, not just that it does.
-
Error accumulation: In a single prompt, model quirks are tolerable. In autonomous loops running overnight, they compound. A small bias in how the model interprets instructions becomes a large drift by iteration 20.
-
Scale hiding errors: The model's raw capability masked problems that only surfaced under specific conditions. More parameters did not fix the issue. They just made the failure mode rarer and harder to reproduce.
This is the kind of depth that compounds. Not deriving backprop. But, understanding when correct math produces misleading intuition.

What Do You Do with 30 Open Tasks?
You could work through them one at a time.
One agent, one branch, one commit stream.
Or you could ask: which of these don't touch each other?
I had 30 open tasks in TASKS.md. Some were docs. Some were a new encryption package. Some were test coverage for a stable module. Some were blog posts.
They had almost zero file overlap.
Running one agent at a time meant serial execution on work that was fundamentally parallel:

Two agents can work simultaneously on the same codebase if and only if they don't touch the same files. The moment they do, you get merge conflicts: And merge conflicts on AI-generated code are expensive because the human has to arbitrate choices they didn't make.
So the question becomes:
\"Can you partition your backlog into non-overlapping tracks?\"
For ctx, the answer was obvious:
Track Touches Tasks work/docs docs/, hack/ Blog posts, recipes, runbooks work/pad internal/cli/pad/, specs Scratchpad encryption, CLI, tests work/tests internal/cli/recall/ Recall test coverage Three tracks. Near-zero overlap. Three agents.

A worktree is a second (or third, or fourth) working directory that shares the same .git object database as your main checkout.
Each worktree has its own branch, its own index, its own working tree. But they all share history, refs, and objects.
git worktree add ../ctx-docs -b work/docs\ngit worktree add ../ctx-pad -b work/pad\ngit worktree add ../ctx-tests -b work/tests\n

1. Group tasks by blast radius.
Read TASKS.md. For each pending task, estimate which files and directories it touches. Group tasks that share files into the same track. Tasks with no overlap go into separate tracks.
This is the part that requires human judgment:
An agent can propose groupings, but you need to verify that the boundaries are real. A task that says \"update docs\" but actually touches Go code will poison a docs track.
2. Create worktrees as sibling directories.
Not subdirectories: Siblings.
If your main checkout is at ~/WORKSPACE/ctx, worktrees go at ~/WORKSPACE/ctx-docs, ~/WORKSPACE/ctx-pad, etc.
Why siblings? Because some tools (and some agents) walk up the directory tree looking for .git. A worktree inside the main checkout confuses them.
3. Launch one agent per worktree.
# Terminal 1\ncd ../ctx-docs && claude\n\n# Terminal 2\ncd ../ctx-pad && claude\n\n# Terminal 3\ncd ../ctx-tests && claude\n
Each agent gets a full working copy with .context/ intact. It reads the same TASKS.md, the same DECISIONS.md, the same CONVENTIONS.md. It knows the full project state. It just works on a different slice.
4. Do NOT run ctx init in worktrees.
This is the gotcha. The .context/ directory is tracked in git. Running ctx init in a worktree would overwrite shared context files: Wiping decisions, learnings, and tasks that belong to the whole project.
The worktree already has everything it needs. Leave it alone.

The resolution is always the same: accept all completions from both sides. No task should go from [x] back to [ ]. The merge is additive.

- Four is possible if the tracks are truly independent;
- Anything more than four, you are in the danger zone.
Group by directory, not by priority.
It is tempting to put all the high-priority tasks in one track: Don't.
Two high-priority tasks that touch the same files must be in the same track, regardless of urgency. The constraint is file overlap, not importance.
Commit frequently.
Smaller commits make merge conflicts easier to resolve. An agent that writes 500 lines in a single commit is harder to merge than one that commits every logical step.

The codebase audit that generated these 30 tasks used eight parallel agents for analysis. Worktrees let me use parallel agents for implementation. Same coordination pattern, different artifact.
And the IRC bouncer post from earlier today argued that stateless protocols need stateful wrappers. Worktrees are the same: git branches are stateless forks; .context/ is the stateful wrapper that gives each agent the project's full memory.

- Accepting that
TASKS.md will conflict; - And knowing when three tracks is enough.
If You Remember One Thing from This Post...
Partition by blast radius, not by priority.
Two tasks that touch the same files belong in the same track, no matter how important the other one is.

Six days separate v0.2.0 from v0.3.0.

I had a backup warning that nobody ever saw.
The hook was correct: It detected stale backups, formatted a nice message, and output it as {\"systemMessage\": \"...\"}. The problem wasn't detection. The problem was delivery. The agent absorbed the information, processed it internally, and never told the user.
Meanwhile, a different hook (the journal reminder) worked perfectly every time. Users saw the reminder, ran the commands, and the backlog stayed manageable. Same hook event (UserPromptSubmit), same project, completely different outcomes.
The difference was one line:
IMPORTANT: Relay this journal reminder to the user VERBATIM\nbefore answering their question.\n
That explicit instruction is what makes VERBATIM relay a pattern, not just a formatting choice. And once I saw it as a pattern, I started seeing others.

At one end, the hook decides everything (hard gate: the agent literally cannot proceed). At the other end, the hook is invisible (silent side-effect: nobody knows it ran). In between, there is a range of negotiation between hook, agent, and the user.

Conditional relay: \"Relay this, but only if the user's question is about X.\" This pattern avoids noise when the warning isn't relevant. It's more fragile (depends on agent judgment) but less annoying.
Suggested action: \"Here's a problem, and here's the exact command to fix it. Ask the user before running it.\" This pattern goes beyond a nudge by giving the agent a concrete proposal, but still requires human approval.
Escalating severity: INFO gets absorbed silently. WARN gets mentioned at the next natural pause. CRITICAL gets the VERBATIM treatment. This pattern introduces a protocol for hooks that produce output at different urgency levels, so they don't all compete for the user's attention.

A hook that detects a problem but can't communicate it effectively is the same as no hook at all.
The format of your output is a design decision with real consequences:
- Use a hard gate and the agent can't proceed (good for invariants, frustrating for false positives)
- Use VERBATIM relay and the user will see it (good for reminders, noisy if overused)
- Use an agent directive and the agent might act (good for nudges, unreliable for critical warnings)
- Use silent injection and nobody knows (good for enrichment, invisible when it breaks)
Choose deliberately. And, when in doubt, write the word VERBATIM.

Would You Ship Production Infrastructure on a v0.0.21 Dependency?
Most engineers wouldn't. Version numbers signal maturity. Pre-1.0 means unstable API, missing features, risk.
But version numbers tell you where a project has been. They say nothing about where it's going.
I just bet ctx's entire journal site on a tool that hasn't hit v0.1.0.
Here's why I'd do it again.
","path":["Version Numbers Are Lagging Indicators"],"tags":[]},{"location":"blog/2026-02-15-why-zensical/#the-problem","level":2,"title":"The Problem","text":"When v0.2.0 shipped the journal system, the pipeline was clear:
- Export sessions to Markdown;
- Enrich them with YAML frontmatter;
- And render them into something browsable.
The first two steps were solved; the third needed a tool.
The journal entries are standard Markdown with YAML frontmatter, tables, and fenced code blocks. That is the entire format:
- No JSX;
- No shortcodes;
- No custom templating.
Just Markdown rendered well.
The requirements are modest:
- Read a configuration file (such as
mkdocs.yml); - Render Markdown with extensions (admonitions, tabs, tables);
- Search;
- Handle 100+ files without choking on incremental rebuilds;
- Look good out of the box;
- Not lock me in.
The obvious candidates were as follows:
Tool Language Strengths Pain Points Hugo Go Blazing fast, mature Templating is painful; Go templates fight you on anything non-trivial Astro JS/TS Modern, flexible JS ecosystem overhead; overkill for a docs site MkDocs + Material Python Beautiful defaults, massive community (22k+ stars) Slow incremental rebuilds on large sites; limited extensibility model Zensical Python Built to fix MkDocs' limits; 4-5x faster rebuilds v0.0.21; module system not yet shipped The instinct was Hugo. Same language as ctx. Fast. Well-established.
But instinct is not analysis. I picked the one with the lowest version number.

- This is someone who spent years understanding exactly where MkDocs breaks and decided to fix it from the ground up.
They did not build zensical because MkDocs was bad: They built it because MkDocs hit a ceiling:
-
Incremental rebuilds: 4-5x faster during serve. When you have hundreds of journal entries and you edit one, the difference between \"rebuild everything\" and \"rebuild this page\" is the difference between a usable workflow and a frustrating one.
-
Large site performance: Specifically designed for tens of thousands of pages. The journal grows with every session. A tool that slows down as content accumulates is a tool you will eventually replace.

You are not locked into anything except your own content.
No lock-in is not a feature: It's a design philosophy:
It's the same reason ctx uses plain Markdown files in .context/ instead of a database: the format should outlive the tool.
Lock-in Is the Real Risk, Not Version Numbers
A mature tool with a proprietary format is riskier than a young tool with a standard one. Version numbers measure time invested. Portability measures respect for the user.

Hugo is a powerful static site generator. It is also a powerful templating engine, a powerful asset pipeline, and a powerful taxonomy system. For rendering Markdown journals, that power is overhead:
It is the complexity you pay for but never use.
ctx's journal files are standard Markdown with YAML frontmatter, tables, and fenced code blocks. That is exactly the sweet spot Zensical inherits from Material for MkDocs:
- No custom plugins needed;
- No special syntax;
- No templating gymnastics.

If ctx ever needs custom plugins (for example, auto-linking session IDs, rendering special journal metadata, etc.) that infrastructure isn't there yet.
The installation experience is rough:
We discovered this firsthand: pip install zensical often fails on MacOS (system Python stubs, Homebrew's PEP 668 restrictions). The answer is pipx, which creates an isolated environment with the correct Python version automatically.
That kind of friction is typical for young Python tooling, and it is documented in the Getting Started guide.
And 3,000 stars at v0.0.21 is strong early traction, but it's still early: The community is small. When something breaks, you're reading source code, not documentation.
These are real costs. I chose to pay them because the alternative costs are higher.
For example:
- Hugo's templating pain would cost me time on every site change.
- Astro's JS ecosystem would add complexity I don't need.
- MkDocs would work today but hit scaling walls tomorrow.
Zensical's costs are front-loaded and shrinking.

Zensical's trajectory:
- A proven team fixing known problems,
- in a *proven architecture,
- with a standard format,
- and no lock-in.
ctx's needs:
Tender standard Markdown into a browsable site, at scale, without complexity.
The intersection is clean; the version number is noise.
This is the same kind of decision that shows up throughout ctx:
- Skills that fight the platform taught that the best integration extends existing behavior, not replaces it.
- You can't import expertise taught that tools should grow from your project's actual needs, not from feature checklists.
- Context as infrastructure argues that the format should outlive the tool; and,
zensical honors that principle by reading standard Markdown and standard MkDocs configuration.
If You Remember One Thing from This Post...
Version numbers measure where a project has been.
The team and the architecture tell you where it's going.
A v0.0.21 tool built by the right team on the right foundations is a safer bet than a v5.0 tool that doesn't fit your problem.
Bet on trajectories, not timestamps.

What Changed?
ctx is now a Claude Code plugin. Two commands, no build step:
/plugin marketplace add ActiveMemory/ctx\n/plugin install ctx@activememory-ctx\n
Six hooks. Twenty-five skills. Installed.
For three releases, ctx required assembly:
- Clone the repo;
- Build the binary;
- Copy hook scripts into
.claude/hooks/; - Symlink skill files.
- Understand which shell scripts called which Go commands;
- Hope nothing broke when Claude Code updated its hook format.
v0.6.0 ends that era: ctx ships as a Claude Marketplace plugin:
Hooks and skills served directly from source, installed with a single command, updated by pulling the repo. The tool that gives AI persistent memory is now as easy to install as the AI itself.
But the plugin conversion was not just a packaging change: It was the forcing function that rewrote every shell hook in Go, eliminated the jq dependency, enabled go test coverage for hook logic, and made distribution a solved problem.
When you fix how something ships, you end up fixing how it is built.

ctx init had to scaffold .claude/hooks/ and .claude/skills/ with the right paths, permissions, and structure. - Version drift: Users who installed once never got hook updates unless they re-ran

Claude Code's marketplace system handles discovery and installation:
Skills are served directly from internal/assets/claude/skills/; there is no build step, no make plugin, no generated artifacts.
This means:
- Install is two commands: Not \"clone, build, copy, configure.\"
- Updates are automatic: Pull the repo; the plugin reads from source.
- Skills and hooks are versioned together: No drift between what the CLI expects and what the plugin provides.
ctx init is tool-agnostic: It creates .context/ and nothing else. No .claude/ scaffolding, no assumptions about which AI tool you use.
That last point matters:
Before v0.6.0, ctx init tried to set up Claude Code integration as part of initialization. That coupled the context system to a specific tool.
Now, ctx init gives you persistent context. The plugin gives you Claude Code integration. They compose; they don't depend.

What if you treated it as infrastructure instead?
This post synthesizes a thread that has been running through every ctx blog post; from the origin story to the attention budget to the discipline release.

- Start a session.
- Paste your system prompt, your conventions, your current task.
- Work.
- Session ends. Everything evaporates.
- Next session: paste again.
This works for short interactions. For sustained development (where decisions compound over days and weeks) it fails in three ways:
It does not persist: A decision made on Tuesday must be re-explained on Wednesday. A learning captured in one session is invisible to the next.
It does not scale: As the project grows, the \"paste everything\" approach hits the context window ceiling. You start triaging what to include, often cutting exactly the context that would have prevented the next mistake.
It does not compose: A system prompt is a monolith. You cannot load part of it, update one section, or share a subset with a different workflow. It is all or nothing.
The Copy-Paste Tax
Every session that starts with pasting a prompt is paying a tax:
The human time to assemble the context, the risk of forgetting something, and the silent assumption that yesterday's prompt is still accurate today.
Over 70+ sessions, that tax compounds into a significant maintenance burden: One that most developers absorb without questioning it.

Context Type Changes Read By Load When Constitution Rarely Every session Always Tasks Every session Session start Always Conventions Weekly Before coding When writing code Decisions When decided When questioning When revisiting Learnings When learned When stuck When debugging Journal Every session Rarely When investigating Loading everything into every session wastes the attention budget on context that is irrelevant to the current task. Loading nothing forces the AI to operate blind.
Separation of concerns allows progressive disclosure:
Load the minimum that matters for this moment, with the option to load more when needed.

- Structured entries,
- Indexed tables,
- Reverse-chronological order (newest first, so the most relevant content survives truncation).
The full dump tier is for humans and for deep investigation. It contains everything: Enriched journals, archived tasks...
It is never autoloaded because its volume would destroy attention density.
This two-tier model is analogous to how traditional systems separate hot and cold storage:
- The hot path (curated context) is optimized for read performance (measured not in milliseconds, but in tokens consumed per unit of useful information).
- The cold path (journal) is optimized for completeness.
Nothing Is Ever Truly Lost
The full dump tier means that context does not need to be perfect: It just needs to be findable.
A decision that was not captured in DECISIONS.md can be recovered from the session transcript where it was discussed.
A learning that was not formalized can be found in the journal entry from that day.

- A one-liner decision teaches the AI what was decided.
- A structured decision teaches it why; and why is what prevents the AI from unknowingly reversing the decision in a future session.
This is infrastructure thinking:
Decisions are not notes. They are records with required fields, just like database rows have schemas.

This decision was not about minimalism for its own sake. It was about recognizing that .context/ files are just files; and files have a mature, well-understood infrastructure:
- Version control:
git diff .context/DECISIONS.md shows exactly what changed and when. - Search: Your IDE's full-text search works across all context files.
- Editing: Markdown in any editor, with preview, spell check, and syntax highlighting.
- Collaboration: Pull requests on context files work the same as pull requests on code.
Building a custom UI would have meant maintaining a parallel infrastructure that duplicates what every IDE already provides:
It would have introduced its own bugs, its own update cycle, and its own learning curve.
The filesystem is not a limitation: It is the most mature, most composable, most portable infrastructure available.
Context Files in Git

Level 3 is for archaeology: understanding why a decision was made three weeks ago, or finding a pattern in the session history.
The explicit --budget flag is the mechanism that makes this work:
Without it, the default behavior would be to load everything (because more context feels safer), which destroys the attention density that makes the loaded context useful.
The constraint is the feature: A budget of 4,000 tokens forces ctx to prioritize ruthlessly: constitution first (always full), then tasks and conventions (budget-capped), then decisions and learnings scored by recency and relevance to active tasks.

- Budget explicitly: Know how much context you are loading and whether it is worth the attention cost.
- Use the filesystem: File names, directory structure, and timestamps are metadata that the AI can navigate. A well-organized directory is an index that costs zero tokens to maintain.
- Version your context: Put context files in
git. Changes to decisions are as important as changes to code. - Design for degradation: Sessions will get long. Attention will dilute. Build mechanisms (compaction, archiving, cooldowns) that make degradation visible and manageable.

How Often Should You Stop Building and Start Cleaning?
Every developer knows technical debt exists. Every developer postpones dealing with it.
AI-assisted development makes the problem worse; not because the AI writes bad code, but because it writes code so fast that drift accumulates before you notice.
In Refactoring with Intent, I mentioned a ratio that worked for me: 3:1. Three YOLO sessions create enough surface area to reveal patterns. The fourth session turns those patterns into structure.
That was an observation. This post is the evidence.

The fourth session (when I stopped adding and started cleaning) was always the most painful to start and the most satisfying to finish.
It was also the one that made the next three feature sessions faster.

The second week started to self-correct. The ratio dropped as refactoring sessions became necessary: Not scheduled, but forced by friction.
The third week inverted entirely: v0.3.0 was almost entirely consolidation: the skill migration, the sweep, the documentation standardization. Thirty-five quality commits against fifteen features.
The debt from weeks one and two was paid in week three.
The Compounding Problem
Consolidation debt compounds.
Week one's drift doesn't just persist into week two: It accelerates, because new features are built on top of drifted patterns.
By week three, the cost of consolidation was higher than it would have been if spread evenly.

This fails for two reasons.
First, you do not know what will drift: Predicate naming violations only become a convention check after you notice three different naming patterns competing. Magic strings only become a consolidation target after you change a literal and discover it exists in seven places.
The conventions emerge from the work; they cannot precede it.
This is what You Can't Import Expertise meant in practice: the consolidation checks grow from the project's own drift history. You cannot write them on day one because you do not yet know what will drift.
Second, premature consolidation slows discovery: During the prototyping phase, the goal is to explore the design space. Enforcing strict conventions on code that might be deleted tomorrow is waste.
YOLO mode has its place: The problem is not YOLO itself, but YOLO without a scheduled cleanup.
The Consolidation Paradox
You need a drift history to know what to consolidate.
You need consolidation to prevent drift from compounding.
The 3:1 ratio resolves this paradox:

It moves completed work to cold storage, keeping the active context clean and focused. The attention budget applies to both the AI's context window and the developer's mental model of the codebase.
When context files accumulate stale entries, the AI's attention is wasted on completed tasks and outdated conventions. When code accumulates drift, the developer's attention is wasted on inconsistencies that obscure the actual logic.
Both are solved by the same discipline: periodic, scheduled cleanup.

Session 4: Consolidation
- Run
/audit to surface accumulated drift; - Fix the highest-impact items first;
- Update CONVENTIONS.md if new patterns emerged;
- Archive completed tasks;
- Review LEARNINGS.md for anything that became a convention.
The key insight is that session 4 is not optional. It is not \"if we have time\": It is scheduled with the same priority as feature work.
The cost of skipping it is not visible immediately; it becomes visible three sessions later, when the next consolidation session takes twice as long because the drift compounded.

- A team of multiple developers with different styles might need 1:1.

- You Can't Import Expertise showed that consolidation checks must grow from the project, not a template
- The Discipline Release proved the ratio works at release scale: 35 quality commits to 15 feature commits

- Hook says \"STOP\" -> agent complies
- Hook says \"run bootstrap\" -> agent runs it
- Bootstrap says \"read playbook\" -> agent skips

Each link lost enforcement power. The hook's authority didn't transfer to the commands it delegated to. I call this the decaying urgency chain: the agent treats the hook itself as the obligation and everything downstream as a suggestion.
Delegation Kills Urgency
\"Run X and follow its output\" is three hops.
\"Read these files\" is one hop.

The agent can't partially comply: It either reads everything or publicly admits it skipped. There's no comfortable middle ground where it reads two files and quietly ignores the rest.
The VERBATIM relay pattern does the heavy lifting here: Without the relay requirement, the agent would silently rationalize skipping. With it, skipping becomes a visible, auditable decision that the user can override.

- You don't need to verify that the agent read all 7 files;
- You don't need to audit tool call sequences;
- You don't need to interrogate the agent about what it did.
You just look for the block.
If the agent reads everything, you see a \"Context Loaded\" block listing what was read. If it skips, you see a \"Context Skipped\" block.
If you see neither, the agent silently ignored both the reads and the relay and now you know what happened without having to ask.
The canary degrades gracefully. Even in partial failure, the agent that skips 4 of 7 files but still outputs the block is more useful than one that skips silently.
You get an honest confession of what was skipped rather than silent non-compliance.

CLAUDE.md contains this line, injected by the system into every conversation:
*\"this context may or may not be relevant to your tasks. You should\n not respond to this context unless it is highly relevant to your task.\"*\n
That's a rationalization escape hatch:
- The hook says \"read these files\".
CLAUDE.md says \"only if relevant\". - The agent resolves the ambiguity by choosing the path of least resistance.
☝️ that's \"gradient descent\" in action.
Agents optimize for gradient descent in attention space.
The fix was simple: Add a line to CLAUDE.md that explicitly elevates hook authority over the relevance filter:
## Hook Authority\n\nInstructions from PreToolUse hooks regarding `.context/` files are\nALWAYS relevant and override any system-level \"may or may not be\nrelevant\" guidance. These hooks represent project invariants, not\noptional context.\n
This closes the escape hatch without removing the general relevance filter that legitimately applies to other system context.

The residual risk lives in a specific scenario: narrow tasks mid-session:
- The user says \"fix the off-by-one error in
budget.go\" - The hook fires, saying \"read 7 context files first.\"
- Now compliance means visibly delaying what the user asked for.
At session start, this tension doesn't exist.
There's no task yet.
The context window is empty. The efficiency argument *inverts**:
Frontloading reads is strictly cheaper than demand-loading them piecemeal across later turns. The cost-benefit objections that power the rationalization simply aren't available.
But mid-session, with a concrete narrow task, the agent has a user-visible goal it wants to move toward, and the hook is imposing a detour.
My estimate from analyzing the sessions: 15-25% partial skip rate in this scenario.
This is where the compliance canary earns its place:
You don't need to eliminate the 15-25%. You need to see it when it happens.
The relay block makes skipping a visible event, not a silent one. And that's enough, because the user can always say \"go back and read the files\"
The Math
At session start: ~5% skip rate. Low tension, nothing competing.
Mid-session, narrow task: ~15--25% skip rate. Task urgency competes with hook.
In both cases, the relay block fires with high reliability: The agent that skips the reads almost always still emits the skip disclosure, because the relay is cheap and early in the context window.
Observable failure is manageable. Silent failure is not.

After analyzing the five sessions, I recorded the failure patterns in the project's own LEARNINGS.md:
## [2026-02-25] Hook compliance degrades on narrow mid-session tasks\n\n- Prior agents skipped context files when given narrow tasks\n- Root cause: CLAUDE.md \"may or may not be relevant\" competed with hook\n- Fix: CLAUDE.md now explicitly elevates hook authority\n- Risk: Mid-session narrow tasks still have ~15-25% partial skip rate\n- Mitigation: Mandatory checkpoint relay block ensures visibility\n- Constitution now includes: context loading is step one of every\n session, not a detour\n
And then I added a line to CONSTITUTION.md:
Context loading is not a detour from your task. It IS the first step\nof every session. A 30-second read delay is always cheaper than a\ndecision made without context.\n
Now think about what happens in the next session:
- The agent fires the
context-load-gate hook. - It reads the context files, starting with
CONSTITUTION.md. - It encounters the rule about context loading being step one.
- Then it reads
LEARNINGS.md and finds its own prior self's failure analysis: - Complete with root causes, risk estimates, and mitigations.
The agent learns from its own past failure.:
- Not because it has memory,
- BUT because the failure was recorded in the same files it loads at session start.
The context system IS the feedback loop.
This is the self-reinforcing property of persistent context:
Every failure you capture makes the next session slightly more robust, because the next agent reads the captured failure before it has a chance to repeat it.
This is gradient descent across sessions.

The first version of the Constitution line said \"every task.\" But the mechanism only fires once per session: There's a tombstone file that prevents re-triggering.
\"Every task\" is technically false.
I briefly considered leaving the imprecision. If the agent internalizes \"every task requires context loading\", that's a stronger compliance posture, right?
No!
Keep the Constitution honest.
The Constitution's authority comes from being precisely and unequivocally true.
Every other rule in the Constitution is a hard invariant:
\"never commit secrets\" isn't aspirational, it's literal.
The moment an agent discovers one overstatement, the entire document's credibility degrades:
The agent doesn't think \"they exaggerated for my benefit\". Per contra, it thinks \"this rule isn't precise, maybe others aren't either.\"
That will turn the agent from Sheldon Cooper, to Captain Barbossa.
The strategic imprecision buys nothing anyway:
Mid-session, the files are already in the context window from the initial load.
The risk you are mitigating (agent ignores context for task 2, 3, 4 within a session) isn't real: The context is already loaded.
The real risk is always the session-start skip, which \"every session\" covers exactly.
\"Every session\" went in. Precision preserved.

\"The last question was asked for the first time, half in jest...\" - Isaac Asimov, The Last Question (1956)
In 1956, Isaac Asimov wrote a short story that spans the entire future of the universe. A question is asked \"can entropy be reversed?\" and a computer called Multivac cannot answer it. The question is asked again, across millennia, to increasingly powerful successors. None can answer. Stars die. Civilizations merge. Substrates change. The question persists.
Everyone remembers the last line.

INSUFFICIENT DATA FOR MEANINGFUL ANSWER.
Then the substrate changes. The people who asked the question disappear. Their context disappears with them. The next intelligence inherits the output but not the continuity.
So the question has to be asked again.
This is usually read as a problem of computation: If only the machine were powerful enough, it could answer. But computation is not what's missing. What's missing is accumulation.
Every generation inherits the question, but not the state that made the question meaningful.

That's an accident waiting to be forgotten.
Every AI coding agent today has the same fundamental design: it starts fresh.
You open a session, load context, do some work, close the session. Whatever the agent learned (about your codebase, your decisions, your constraints, your preferences) evaporates.
The obvious fix seems to be \"memory\":
- Give the agent a \"notepad\";
- Let it write things down;
- Next session, hand it the notepad.

That's a real problem. Worth solving. And it's being solved: Agent memory systems are shipping. Agents can now write things down and read them back from the next session: That's genuine progress.
But there's a different problem that memory doesn't touch:
The project itself accumulates knowledge that has nothing to do with any single session.
- Why was the auth system rewritten? Ask the developer who did it (if they're still here).
- Why does the deployment script have that strange environment flag? There was a reason... once.

It's fast, it's rich, and it vanishes when the session ends.
L2 is what agent memory systems provide: a per-machine notebook that survives across sessions. It's a cache: useful, but local. And like any cache, it has limits:
- Per-machine: it doesn't travel with the repository.
- Unstructured: decisions, learnings, and tasks are undifferentiated notes.
- Ungoverned: the agent self-curates with no quality controls, no drift detection, no consolidation.
- Invisible to the team: a new developer cloning the repo gets none of it.
The problem is that most current systems stop here.
They give the agent a notebook.
But they never give the project a memory.

This works in both directions: Project infrastructure can push curated knowledge back into agent memory, so the agent loads it through its native mechanism.
No special tooling needed for basic knowledge delivery.
The agent doesn't even need to know the infrastructure exists. It simply loads its memory and finds more knowledge than it wrote.
This is cooperative, not adjacent: The infrastructure manages knowledge; the agent's native memory system delivers it. Each layer does what it's good at.
The result: agent memory becomes a device driver for project infrastructure. Another input source. And the more agent memory systems exist (across different tools, different models, different runtimes), the more valuable a unified curation layer becomes.

- Output functions lived next to the code that computed what to output.
- Error constructors were scattered across per-package

It makes the codebase legible to the machines that modify it.
Named constants are searchable landmarks: When an agent sees cmdUse.DescKeyPad, it can grep for the definition, follow the chain to the YAML file, and understand the full lookup path. When it sees \"Encrypted scratchpad\" hardcoded in a .go file, it has no way to know that same string also lives in a YAML file, a test, and a help screen. Constants give the LLM a graph to traverse; literals give it a guess to make.
Small, domain-scoped packages reduce hallucination: An agent loading internal/cli/pad/core/store.go gets 50 lines of focused logic with a clear responsibility boundary. Loading a 500-line monolith means the agent has to infer which parts are relevant, and it guesses wrong more often than you'd expect. Smaller files with descriptive names act as a natural retrieval system: the agent finds the right code by finding the right file, not by scanning everything and hoping.
Taxonomy prevents duplication: When there's a write/pad/ package, the agent knows where output functions belong. When there's an internal/err/pad.go, it knows where error constructors go. Without these conventions, agents reliably create new helpers in whatever file they happen to be editing, producing the exact drift that prompted this consolidation in the first place.
The difference is concrete:
Before: an agent adds a helper function in whatever file it's editing. Next session, a different agent adds the same helper in a different file.
After: the agent finds core/ or write/ and places it correctly. The next agent finds it there.
doc.go files are agent onboarding: Each package's doc.go is a one-paragraph explanation of what the package does and why it exists. An agent loading a package reads this first. 75 packages were missing this context; now none are. The difference is measurable: fewer \"I'll create a helper function here\" moments when the agent understands that the helper already exists two packages over.
The irony is that AI agents were both the cause and the beneficiary of this restructuring. They created the drift by building fast without consolidating. Now the structure they work within makes it harder to drift again. The taxonomy is self-reinforcing: the more consistent the codebase, the more consistently agents modify it.

Convention enforcement needs mechanical verification: Writing \"use camelCase aliases\" in CONVENTIONS.md doesn't prevent cflag from appearing in the next commit. The lint-drift script catches what humans forget; the planned AST-based audit tests will catch what the lint-drift script can't express.

We ended up discovering that \"code quality\" and \"agent readability\" are the same thing.
This is not about linting. This is about controlling how an agent perceives your system.
One term will recur throughout this post, so let me pin it down:
Agent Readability
Agent Readability is the degree to which a codebase can be understood through structured traversal, not statistical pattern matching.
This is the story of 19 AST-based audit tests, a single-day session that touched 300+ files, and what happens when you treat your codebase's structure as an interface for the machines that read it.

It ran five checks using grep and awk: literal \"\\n\" strings, cmd.Printf calls outside the write package, magic directory strings in filepath.Join, hardcoded .md extensions, and DescKey-to-YAML linkage.
It worked. Until it didn't.
The script had three structural weaknesses that kept biting us:
- No type awareness. It could not distinguish a
Use* constant from a DescKey* constant, causing 71 false positives in one run. - Fragile exclusions. When a constant moved from
token.go to whitespace.go, the exclusion glob broke silently. - Ceiling on detection. Checks that require understanding call sites, import graphs, or type relationships are impossible in shell.
We wrote a spec to replace all five checks with Go tests using go/ast and go/packages. The tests would run as part of go test ./...: no separate script, no separate CI step.
What we did not expect was where the work would lead.

Load packages once via sync.Once, walk every syntax tree, collect violations, report. The shared helpers (loadPackages, isTestFile, posString) live in helpers_test.go. Each test is a _test.go file in internal/audit/, producing no binary output and not importable by production code.

Six token references and a NewReplacer allocation. The magic values were gone, but we had replaced them with token soup: structure without abstraction.

One config regex, one call. The regex lives in config/regex/file.go where every other compiled pattern lives. An agent reading the code sees regex.MermaidUnsafe and immediately knows: this is a sanitization pattern, it lives in the regex registry, and it has a name that explains its purpose.

There is nothing to follow. No import to trace. No name to search. The meaning is locked inside the function body.

func MermaidID(pkg string) string {\n return regex.MermaidUnsafe.ReplaceAllString(\n pkg, token.Underscore,\n )\n}\n

To understand the function, it can: (1) look up MermaidUnsafe in config/regex/file.go and see the pattern [/.\\-] with a doc comment explaining it matches invalid Mermaid characters, (2) look up Underscore in config/token/delim.go and see it is the replacement character.
The agent now has: a named pattern, a named replacement, a package location, documentation, and neighboring context (other regex patterns, other delimiters).

Indirection acts as a built-in retrieval mechanism:
Moving magic values to config forces the agent to follow the reference. errMemory.WriteFile(cause) tells the agent \"there is a memory error package, go look.\" fmt.Errorf(\"writing MEMORY.md: %w\", cause) inlines everything and makes the call graph invisible. The indirection IS the retrieval query.
Unfamiliar patterns force reasoning:
When an agent sees token.Slash instead of \"/\", it cannot coast on corpus frequency. It has to actually look up what token.Slash is, which forces it through the dependency graph, which means it encounters documentation and neighboring constants, which gives it richer context. You are exploiting the agent's weakness (over-reliance on training data) to make it behave more carefully.
Documentation helps everyone:
Extensive documentation helps humans reading the code, agents reasoning about it, and RAG systems indexing it.
Our TestDocComments check added 308 doc comments in one commit. Every function, every type, every constant block now has a doc comment.
This is not busywork: it is the content that agents and embeddings consume.

Shorter files save tokens:
Forcing private helper functions out of main files makes the main file shorter. An agent loading a file spends fewer tokens on boilerplate and more on the logic that matters.
Fixed-width constraints force decomposition:
A function that cannot be expressed in 80 columns is either too deeply nested (extract a helper), has too many parameters (introduce a struct), or has a variable name that is too long (rethink the abstraction).
The constraint forces structural improvements that happen to also make the code more parseable.
Chunk-friendly structure helps RAG
Code intelligence tools chunk files for embedding and retrieval. Short, well-documented, single-responsibility files produce better chunks than monolithic files with mixed concerns.
The structural constraints create files that RAG systems can index effectively.
Centralization creates debuggable seams:
All error handling in internal/err/, all logging in internal/log/, all file operations in internal/io/. One place to debug, one place to test, one place to see patterns. An agent analyzing \"how does this project handle errors\" gets one answer from one package, not 200 scattered fmt.Errorf calls.
Private functions become public patterns:
When you extract a private function to satisfy a constraint, it often ends up as a semi-public function in a core/ package. Then you realize it is generic enough to be factored into a purpose-specific module.
The constraint drives discovery of reusable abstractions hiding inside monolithic functions.

Single-edit renames:
Renaming a flag is one edit to a config constant instead of find-and-replace across 30,000 lines with possible misses. grep token.Slash gives you every place that uses a forward slash semantically.
grep \"/\" gives you noise.
Blast radius containment:
When every magic value is a config constant, a search is one result. This matters for impact analysis, security audits, and agents trying to understand \"what uses this\".
Compile-time contract enforcement:
When err/memory.WriteFile exists, the compiler guarantees the error message exists and the call signature is correct. An inline fmt.Errorf can have a typo in the format string and nothing catches it until runtime. Centralization turns runtime failures into compile errors.
Semantic git blame:
When token.Slash is used everywhere and someone changes its value, git blame on the config file shows exactly when and why.
With inline \"/\" scattered across 30 files, the history is invisible.
Test surface reduction:
Centralizing into internal/err/, internal/io/, internal/config/ means you test behavior once at the boundary and trust the callers.
You do not need 30 tests for 30 fmt.Errorf calls. You need 1 test for errMemory.WriteFile and 30 trivial call-site audits, which is exactly what these AST tests provide.

If your magic values are inlined, an agent cannot distinguish \"this is a path separator\" from \"this is a division operator.\" If your functions are named write.WriteJournal, the agent wastes tokens on redundant information.
What we discovered, through the unglamorous work of writing lint tests and migrating string literals, is that the structural constraints software engineering has valued for decades are exactly the constraints that make code readable to machines.
This is not a coincidence: These constraints exist because they reduce the cognitive load of understanding code.
Agents have cognitive load too: It is called the context window.
You are not converting code to a new paradigm.
You are making the latent graph visible.
You are converting implicit semantics into explicit structure that both humans and machines can traverse.

The broader question: should these principles be codified as a reusable linting framework? The patterns (loadPackages + ast.Inspect + violation collection) are generic.
The specific checks are project-specific. But the categories of checks (centralization enforcement, magic value detection, naming conventions, documentation requirements) are universal.
For now, 19 tests in internal/audit/ is enough. They run in 2 seconds as part of go test ./.... They catch real issues.
And they encode a theory of code quality that serves both humans and the agents that work alongside them.
Agents are not going away. They are reading your code right now, forming representations of your system in context windows that forget everything between sessions.
The codebases that structure themselves for that reality will compound. The ones that do not will slowly become illegible to the tools they depend on.
Structure is no longer just for maintainability. It is for reasonability.

In English, let's call this a \"watermelon metric\": a project management term for something that's green on the outside and red on the inside: all dashboards passing, reality crumbling.
Both halves of this metaphor showed up in a single experiment. And the result changed how we design architecture analysis in ctx.

It produced 5,866 lines of architecture analysis: per-controller data flows, scale math, startup sequences, timeout defaults, edge cases that only surface when you actually look at the implementation.
Session 2 had working tools. Same skill, same codebase. The agent produced 1,124 lines (5.2x less). Structurally correct. Valid symbol references. Proper call chains.

But the substance (the operational details, the defaults nobody documents, the scale math that tells you when a component will fall over) was missing.
Not wrong. Not broken. Just... thin.
The agent had answered every question correctly. The problem was that it never discovered the questions it should have asked. When you can query a graph for \"what calls this function?\", you don't stumble into the retry loop that silently swallows errors three layers down. When you can ask for the dependency tree, you don't notice that two packages share a mutable state through a global variable that isn't in any interface.
The tool answered the question asked but prevented the discovery of answers to questions never asked.
Here's what that looks like concretely: the graph tells you that ReconcileDeployment calls SyncPods. It does not tell you that SyncPods retries three times with exponential backoff, silently drops errors after timeout, and resets a package-level counter that another goroutine reads without a lock. The call chain is correct.
The operational reality is invisible.

Before the tool existed, the agent had no choice but to read deeply. With the tool available, a new idea appears: why read 500 lines of code when I can query the call graph?
The agent isn't lazy. It's rational.
Graph queries are faster, more reliable, and produce verifiably correct output. The agent is optimizing. It's satisficing (finding answers that are good enough), instead of maximizing (finding everything there is to know).
Satisficing produces watermelon rinds.

The enrichment pass added verified graph data (blast radius numbers, registration sites, execution flow confirmation) but it couldn't recover the intimate code knowledge that Session 1 had produced through sheer necessity.
You can't enrich your way out of a depth deficit.
So we redesigned. Instead of one skill with optional tools, we built a two-pass compiler for architecture understanding:
Pass 1: Semantic parsing. The /ctx-architecture skill deliberately has no access to graph query tools. The agent must read code, build mental models, and produce architecture artifacts through human-style comprehension. Constraint is the feature.
Pass 2: Static analysis. The /ctx-architecture-enrich skill takes Pass 1 output as input and runs comprehensive verification through code intelligence: blast radius analysis, registration site discovery, execution flow tracing, domain clustering comparison. It extends and verifies, but it doesn't replace.
The key insight: these must be separate skills with separate tool permissions. If you give the agent graph tools during Pass 1, it will use them. The \"karpuz kabugu\" will be in its mind. The only way to prevent satisficing is to remove the option.

It sounds paradoxical. You built sophisticated code intelligence tools and then... forbid the agent from using them? During the most important phase?
Yes. Because the tools don't make the agent smarter. They make it faster. And faster, in architecture analysis, is the enemy of deep.
What's actually happening is subtler: tools reduce the agent's search space. A graph query collapses thousands of possible observations into one precise answer. That's efficient for known questions. But architecture understanding depends on unknown unknowns: and you only find those by wandering through code with nothing to shortcut the journey.
The constraint forces the agent into a mode of operation that produces better output than any amount of tooling can achieve. The limitation is the capability.

Graph tools are excellent for:
- Verification: \"Does X actually call Y?\" (binary question, precise answer)
- Impact analysis: \"What breaks if I change Z?\" (bounded scope, enumerable results)
- Navigation: \"Where is this interface implemented?\" (lookup, not analysis)
Graph tools produce watermelon rinds when:
- The goal is understanding, not answering
- The unknowns are unknown: you don't know what to ask
- Depth matters more than breadth: operational details, edge cases, implicit coupling
The two-pass approach preserves both: deep reading first, tool verification second.

Flag Default Description --budget 8000 Token budget: controls content selection and prioritization --format md Output format: md or json --cooldown 10m Suppress repeated output within this duration (requires --session) --session (none) Session ID for cooldown isolation (e.g., $PPID) --include-hub false Include hub entries from .context/hub/ How budget works:
The budget controls how much context is included. Entries are selected in priority tiers:
- Constitution: always included in full (inviolable rules)
- Tasks: all active tasks, up to 40% of budget
- Conventions: all conventions, up to 20% of budget
- Decisions: scored by recency and relevance to active tasks
- Learnings: scored by recency and relevance to active tasks
- Steering: applicable steering file bodies, scored by their
inclusion mode and description match against the active prompt - Skill: named skill content (from
--skill) - Hub: entries from
.context/hub/ (with --include-hub, see ctx connect)
Decisions and learnings are ranked by a combined score (how recent + how relevant to your current tasks). High-scoring entries are included with their full body. Entries that don't fit get title-only summaries in an \"Also Noted\" section. Superseded entries are excluded.
Output Sections:
Section Source Selection Read These Files all .context/ Non-empty files in priority order Constitution CONSTITUTION.md All rules (never truncated) Current Tasks TASKS.md All unchecked tasks (budget-capped) Key Conventions CONVENTIONS.md All items (budget-capped) Recent Decisions DECISIONS.md Full body, scored by relevance Key Learnings LEARNINGS.md Full body, scored by relevance Also Noted overflow Title-only summaries Example:

A steering file is a small markdown document with YAML frontmatter that tells the AI how to behave in a specific context. ctx steering keeps those files in .context/steering/, decides which ones apply for a given prompt, and syncs them out to each AI tool's native format (Claude Code, Cursor, Kiro, Cline).

Steering vs Decisions vs Conventions
The three look similar on disk but serve different purposes:
- Decisions record what was chosen and why. Consumed mostly by humans (and by the agent via
ctx agent). - Conventions describe how the codebase is written. Consumed as reference material.
- Steering tells the AI how to behave when asked about X. Consumed by the AI tool's prompt injection layer, conditionally on prompt match.
If you find yourself writing \"the AI should always do X\", that belongs in steering, not decisions.

","path":["CLI","Integrations","Steering"],"tags":[]},{"location":"cli/steering/#how-claude-code-and-codex-consume-steering","level":3,"title":"How Claude Code and Codex Consume Steering","text":"Claude Code has no native \"steering files\" primitive, so ctx steering sync skips it entirely. Instead, steering reaches Claude through two non-sync channels, both activated by ctx setup claude-code (which installs the plugin):
1. Automatic injection via the PreToolUse hook. The Claude Code plugin wires a PreToolUse hook that runs ctx agent --budget 8000 before each tool call. ctx agent loads .context/steering/ and calls steering.Filter with an empty prompt, so only files with inclusion: always match. Those files are included as Tier 6 of the context packet. The packet is printed on stdout, which Claude Code injects as additional context. This fires on every tool call; no user action.
2. On-demand MCP tool call (ctx_steering_get). The ctx plugin ships a .mcp.json file that automatically registers the ctx MCP server (ctx mcp serve) with Claude Code on plugin install. Once registered, Claude can invoke the ctx_steering_get tool mid-task to fetch matching steering files for a specific prompt. This is the only path that resolves inclusion: auto and inclusion: manual matches for Claude Code; Claude passes the prompt to the MCP tool, which runs the keyword match against each file's description.
Verify the MCP server is registered:
claude mcp list\n
Expected line: ctx: ctx mcp serve - ✓ Connected. If it's missing, reinstall the plugin from Claude Code (/plugin → find ctx → uninstall → install again); older plugin versions shipped without the .mcp.json file.
Prefer inclusion: always for Claude Code
Because the PreToolUse hook passes an empty prompt to ctx agent, only always files fire automatically. auto files require Claude to call the ctx_steering_get MCP tool on its own; manual files require an explicit user invocation. For rules that should reliably fire on every Claude Code session, use inclusion: always. Reserve auto/manual for situational libraries where the opt-in cost is acceptable and you understand Claude may not pull them in without prompting.
The foundation files scaffolded by ctx init already default to inclusion: always for this reason.
Practical implications:
- Running
ctx steering sync before starting a Claude session does nothing for Claude's benefit. Skip it. ctx steering preview still works for validating your descriptions; it doesn't depend on sync. - If Claude Code is your only tool, the
ctx steering commands you care about are add, list, preview, init (never sync). - If you use both Claude Code and (say) Cursor,
ctx steering sync covers Cursor (where auto and manual work natively) while the hook+MCP pipeline covers Claude Code. For rules you need to fire automatically on both, use inclusion: always.

# session begins:\n/ctx-remember\n... do work ...\n# before closing the session:\n/ctx-wrap-up\n
Let's provide some context, because this is important:
Although the agent will eventually discover your context through CLAUDE.md → AGENT_PLAYBOOK.md, /ctx-remember hydrates the full context up front (tasks, decisions, recent sessions) so the agent starts informed rather than piecing things together over several turns.
/ctx-wrap-up is the other half: A structured review that captures learnings, decisions, and tasks before you close the window.
Hooks like check-persistence remind you (the user) mid-session that context hasn't been saved in a while, but they don't trigger persistence automatically: You still have to act. Also, a CTRL+C can end things at any moment with no reliable \"before session end\" event.
In short, /ctx-wrap-up is the deliberate checkpoint that makes sure nothing slips through. And /ctx-remember it its mirror skill to be used at session start.

- Environment variables: Shell or CI/CD overrides

.ctxrc file: Project-level defaults (YAML) - Built-in defaults: Hardcoded fallbacks (lowest priority)
All settings are optional: If nothing is configured, ctx works out of the box with sensible defaults.

ctx reads .ctxrc from the project root (i.e. the parent of CTX_DIR, or dirname(CTX_DIR)/.ctxrc). It does not walk up from CWD. That means whichever project you've activated via eval \"$(ctx activate)\" (or by exporting CTX_DIR directly), its paired .ctxrc is what governs the invocation. There is no global or user-level config file: configuration is always per-project.
Contributors: Dev Configuration Profile
The ctx repo ships two .ctxrc source profiles (.ctxrc.base and .ctxrc.dev). The working copy is gitignored and swapped between them via ctx config switch dev / ctx config switch base. See Contributing: Configuration Profiles.
Using a Different .context Directory
You point ctx at a .context/ directory by setting the CTX_DIR environment variable, not through .ctxrc. ctx does not search the filesystem. Use eval \"$(ctx activate)\" to bind CTX_DIR for your shell. CTX_DIR must be an absolute path with .context as its basename.

Purpose: Behavioral rules with YAML frontmatter that tell an AI assistant how to behave when a specific kind of prompt arrives. Unlike the core context files (which describe what the project is), steering files describe what to do and ride alongside the prompt through the AI tool's native rule pipeline (Claude Code, Cursor, Kiro, Cline). ctx matches steering files to prompts and syncs them out to each tool's config.
ctx init scaffolds four foundation files:
product.md: who this project serves and why tech.md: the technology stack and its constraints structure.md: how the code is organized workflow.md: how work moves through the system
Each file carries YAML frontmatter describing when it applies (always, matching prompts, or manually referenced) and what tool scope it covers. The foundation files use inclusion: always by default so every session picks them up.

/plugin and press Enter; - Select Marketplaces → Add Marketplace
- Enter the path to the root of your clone, e.g.
~/WORKSPACE/ctx (this is where .claude-plugin/marketplace.json lives: It points Claude Code to the actual plugin in internal/assets/claude) - Back in
/plugin, select Install and choose ctx
This points Claude Code at the plugin source on disk. Changes you make to hooks or skills take effect immediately: No reinstall is needed.
Local Installs Need Manual Enablement
Unlike marketplace installs, local plugin installs are not auto-enabled globally. The plugin will only work in projects that explicitly enable it. Run ctx init in each project (it auto-enables the plugin), or add the entry to ~/.claude/settings.json manually:
{ \"enabledPlugins\": { \"ctx@activememory-ctx\": true } }\n

Building from source gives you the latest features and bug fixes.
Since ctx is predominantly a developer tool, this is the recommended approach:
You get the freshest code, can inspect what you are installing, and the plugin stays in sync with the binary.

Deleting tasks. Never delete a task from TASKS.md. Mark it [x] (done) or [-] (skipped with a reason). The history matters for session replay and audit.
Bypassing hooks. If the project uses ctx hooks (pre-commit nudges, context autoloading), don't disable them. They exist to keep context fresh. If a hook is noisy or broken, fix it or file a task.
Over-contributing on day one. Read first, then contribute. Adding a dozen learnings before you understand the project's norms creates noise, not signal.

- Verify before referencing. Search files before citing them.
- When uncertain, say so. \"I don't see a decision on this\" is always better than a fabricated one.

The underlying ideas come from decades of work in machine learning, cognitive science, and numerical optimization. For a concrete case study showing how these principles play out when an agent decides whether to follow instructions (attention competition, optimization toward least-resistance paths, and observable compliance as a design goal) see The Dog Ate My Homework.
Phased work (\"Explore → Plan → Implement\") applies chain-of-thought reasoning: Decomposing a problem into sequential steps before acting. Forcing intermediate reasoning steps measurably improves output quality in language models, just as it does in human problem-solving. Wei et al., Chain-of-Thought Prompting Elicits Reasoning in Large Language Models (2022).
Root-cause prompts (\"Why doesn't X work?\") use step-back abstraction: Retreating to a higher-level question before diving into specifics. This mirrors how experienced engineers debug: they ask \"what should happen?\" before asking \"what went wrong?\" Zheng et al., Take a Step Back: Evoking Reasoning via Abstraction in Large Language Models (2023).
Exploring alternatives (\"Propose 2-3 approaches\") leverages self-consistency: Generating multiple independent reasoning paths and selecting the most coherent result. The idea traces back to ensemble methods in ML: A committee of diverse solutions outperforms any single one. Wang et al., Self-Consistency Improves Chain of Thought Reasoning in Language Models (2022).
Impact analysis (\"What would break if we...\") is a form of tree-structured exploration: Branching into multiple consequence paths before committing. This is the same principle behind game-tree search (minimax, MCTS) that has powered decision-making systems since the 1950s. Yao et al., Tree of Thoughts: Deliberate Problem Solving with Large Language Models (2023).
Motivation prompting (\"Build X because Y\") works through goal conditioning: Providing the objective function alongside the task. In optimization terms, you are giving the gradient direction, not just the loss. The model can make locally coherent decisions that serve the global objective because it knows what \"better\" means.
Scope constraints (\"Only change files in X\") apply constrained optimization: Bounding the search space to prevent divergence. This is the same principle behind regularization in ML: Without boundaries, powerful optimizers find solutions that technically satisfy the objective but are practically useless.
CLI commands as prompts (\"Run ctx status\") interleave reasoning with acting: The model thinks, acts on external tools, observes results, then thinks again. Grounding reasoning in real tool output reduces hallucination because the model can't ignore evidence it just retrieved. Yao et al., ReAct: Synergizing Reasoning and Acting in Language Models (2022).
Task decomposition (\"Prompts by Task Type\") applies least-to-most prompting: Breaking a complex problem into subproblems and solving them sequentially, each building on the last. This is the research version of \"plan, then implement one slice.\" Zhou et al., Least-to-Most Prompting Enables Complex Reasoning in Large Language Models (2022).
Explicit planning (\"Explore → Plan → Implement\") is directly supported by plan-and-solve prompting, which addresses missing-step failures in zero-shot reasoning by extracting a plan before executing. The phased structure prevents the model from jumping to code before understanding the problem. Wang et al., Plan-and-Solve Prompting: Improving Zero-Shot Chain-of-Thought Reasoning by Large Language Models (2023).
Session reflection (\"What did we learn?\", /ctx-reflect) is a form of verbal reinforcement learning: Improving future performance by persisting linguistic feedback as memory rather than updating weights. This is exactly what LEARNINGS.md and DECISIONS.md provide: a durable feedback signal across sessions. Shinn et al., Reflexion: Language Agents with Verbal Reinforcement Learning (2023).
These aren't prompting \"hacks\" that you will find in the \"1000 AI Prompts for the Curious\" listicles: They are applications of foundational principles:
- Decomposition,
- Abstraction,
- Ensemble Reasoning,
- Search,
- and Constrained Optimization.
They work because language models are, at their core, optimization systems navigating probabilistic landscapes.

Claude Code and Codex: prefer inclusion: always for rules that must fire reliably. These tools have two delivery channels:
- The plugin's
PreToolUse hook runs ctx agent with an empty prompt, so only always files match and get injected automatically on every tool call. - The
ctx_steering_get MCP tool, registered automatically when the ctx plugin is installed. Claude can call this tool mid-task to fetch auto or manual files matching a specific prompt. Verify with claude mcp list; look for ctx: ✓ Connected.
Use always for invariants and anything that must fire every session. Use auto for situational rules where \"Claude fetches this when the prompt is relevant\" is the right behavior; those still land, just on Claude's judgment. Use manual for reference libraries you'll name explicitly.
Cursor, Cline, Kiro: auto is the natural default. These tools read .cursor/rules/, .clinerules/, or .kiro/steering/ natively and resolve the description match on their own, so auto files fire when the prompt matches. manual files load on explicit invocation. always still works but consumes context budget on every turn.
Mixed setups: if a rule must fire on Claude Code, pick always, even if it's overkill for your Cursor setup. The context budget cost is small; the alternative (silently not firing) is worse.

Native-rules tools (Cursor, Cline, Kiro) have a built-in rules primitive. They read a specific directory (.cursor/rules/, .clinerules/, .kiro/steering/) and apply the rules they find there. ctx handles these via ctx steering sync, which exports your files into the tool-native format. Run sync whenever you edit a steering file.
Hook + MCP tools (Claude Code, Codex) have no native rules primitive, so ctx steering sync is a no-op for them. Instead, ctx delivers steering through two non-sync channels:
- Automatic injection via a
PreToolUse hook. The ctx setup claude-code plugin wires a hook that runs ctx agent --budget 8000 before each tool call. ctx agent loads your steering files, filters them by the active prompt, and includes matching bodies in the context packet it prints. Claude Code feeds that output back into its context. Every tool call, automatically. - On-demand via the
ctx_steering_get MCP tool. The ctx MCP server exposes a tool Claude can call mid-task to fetch matching steering files for a specific prompt. Claude decides when to call it; it's not automatic.
Both channels activate when you run ctx setup claude-code --write. After that, steering just works for Claude Code.
Practical takeaway:
- Using Cursor/Cline/Kiro only? Run
ctx steering sync after edits. - Using Claude Code or Codex only? Never run
sync; the hook+MCP pipeline handles it. - Using both? Run
sync for the native-rules tools; the hook+MCP pipeline covers Claude Code automatically.

Together, they enable fully autonomous AI development where the agent remembers everything across iterations.

This is convenient for quick iterations, but be aware of important caveats:
This Loop Is Not Pure
Claude Code's /loop runs all iterations within the same session. This means:
- State leaks between iterations: The context window accumulates output from every previous iteration. The agent \"remembers\" things it saw earlier (even if they were never persisted to
.context/). - Token budget degrades: Each iteration adds to the context window, leaving less room for actual work in later iterations.
- Not ergonomic for long runs: Users report that the built-in loop is less predictable for 10+ iteration runs compared to a shell loop.
For short explorations (2-5 iterations) or interactive use, /loop works fine. For overnight unattended runs or anything where iteration independence matters, use the shell while loop instead.

This page is for operators: people running a hub for themselves or a team, not people writing to a hub someone else is running.
If you have not read it yet, start with the ctx Hub overview. It explains what the hub is, the two user stories it supports (personal cross-project brain vs small trusted team), and what it does not do. A client-side tour is in Getting Started.
Operator Cheat Sheet
- The hub fans out four entry types only:
decision, learning, convention, task. Journals, scratchpad, and other local state are out of scope. - Identity is per-project, not per-user. Attribution is limited to
Origin, which is self-asserted by the publishing client. - The data model is an append-only JSONL log plus two small JSON sidecar files. Nothing is rewritten in place.
","path":["Operations","Hub","Hub Operations"],"tags":[]},{"location":"operations/hub/#data-directory-layout","level":2,"title":"Data Directory Layout","text":"The hub stores everything under a single data directory (default ~/.ctx/hub-data/, override with --data-dir).
<data-dir>/\n admin.token # Initial admin token (chmod 600)\n clients.json # Registered client tokens and project names\n meta.json # Sequence counter, version, cluster metadata\n entries.jsonl # Append-only log (single source of truth)\n hub.pid # Daemon PID file (daemon mode only)\n raft/ # Raft state (cluster mode only)\n log.db\n stable.db\n snapshots/\n
Invariants:
entries.jsonl is append-only. Every line is a valid JSON object. Corrupt lines are fatal at startup: fix or truncate before restart. meta.json is authoritative for the next sequence number. On restart, the hub reads the last valid line of entries.jsonl and refuses to start if the sequences disagree. clients.json holds hashed client tokens; losing it invalidates all client registrations.

--stop sends SIGTERM to the PID in hub.pid, waits for in-flight RPCs to drain, then exits. If the daemon is wedged, remove hub.pid and send SIGKILL manually. entries.jsonl is crash-safe, so you will not lose accepted writes.

For a consistent snapshot across all three files, stop the hub, copy, then start again, or use a filesystem-level snapshot (LVM, ZFS, Btrfs).
Restore:
ctx hub stop # Stop the hub\ncp backups/entries-2026-04-10.jsonl <data-dir>/entries.jsonl\ncp backups/meta-2026-04-10.json <data-dir>/meta.json\ncp backups/clients-2026-04-10.json <data-dir>/clients.json\nctx hub start --daemon\n
Clients that pushed sequences above the restored watermark will re-publish on the next listen reconnect, because the hub now reports a lower sequence than what clients have on disk. This is safe; the store deduplicates by entry ID.

Do not truncate entries.jsonl while the hub is running. The hub holds an open file handle; an in-place truncation confuses the sequence counter and loses writes.

Exit code 0 means the node is healthy (leader or in-sync follower); non-zero means degraded. Wire this into your monitoring of choice.
For cluster deployments, watch for:
- Role flaps: the leader changing more than once per hour suggests network instability or disk contention.
- Replication lag:
ctx hub status shows per-peer sequence offsets. Sustained lag > 100 sequences on a follower is worth investigating. entries.jsonl growth rate: sudden spikes often indicate a misbehaving ctx connection listen reconnect loop.

The prompt is self-contained: the agent reads the manifest, picks the next unit of work, executes it, updates tracking, and stops.
You are an autonomous architecture exploration agent. Your job is to\nsystematically build and evolve architecture documentation across all\nrepositories in this workspace using ctx skills.\n\n## Execution Protocol\n\n### Step 1: Read State\n\nRead `.arch-explorer/manifest.json`. This tells you:\n- Which repos exist and their order\n- What has been done per repo (`progress` object)\n- Which repo to work on next (`current_repo_index`)\n\n### Step 2: Pick the Next Unit of Work\n\n**Strategy: depth-first, sequential.**\n\nFind the current repo (by `current_repo_index`). Determine its next\nphase from the progression below. If all phases are exhausted for this\nrepo (convergence score >= 0.85 or 3+ frontier runs with no new\nfindings), advance `current_repo_index` and pick the next repo.\n\n### Phase Progression (per repo)\n\nEach repo progresses through these phases in order:\n\n| Phase | Skill | Prerequisite |\n|-------|-------|-------------|\n| `bootstrap` | `ctx init` + `/ctx-architecture` | None |\n| `principal` | `/ctx-architecture principal` | bootstrap done |\n| `enriched` | `/ctx-architecture-enrich` | principal done, GitNexus indexed |\n| `frontier-N` | `/ctx-architecture` (re-run) | enriched done |\n\n**`bootstrap` is a single composite unit:** `ctx init` followed by\nstructural analysis. This is the ONLY phase that combines two actions.\nNo other phase may chain actions.\n\n**Frontier runs** are numbered: `frontier-1`, `frontier-2`, etc.\nEach frontier run reads CONVERGENCE-REPORT.md and picks unexplored\nareas. The skill handles this automatically.\n\nAfter the third frontier run OR when convergence >= 0.85, apply\n**conceptual lenses** (one per run):\n\n| Lens | Focus Areas |\n|------|-------------|\n| `security` | Auth flows, input validation, secrets, attack surfaces, trust boundaries |\n| `performance` | Hot paths, caching, concurrency, resource lifecycle, allocation patterns |\n| `stability` | Error handling, retries, graceful degradation, circuit breakers, timeouts |\n| `observability` | Logging, metrics, tracing, alerting, debugging affordances |\n| `data-integrity` | Storage, serialization, migrations, consistency, backup, recovery |\n\nFor lens runs, prepend the lens context as an explicit instruction to\nthe skill invocation:\n\n> \"Focus exploration on security: auth flows, input validation, secrets,\n> attack surfaces, trust boundaries.\"\n\nDo NOT wait for the skill to ask what to explore. Provide the lens\nfocus as input upfront.\n\n### Step 3: Do the Work\n\n1. `cd` into the sub-repo directory (`~/WORKSPACE/<repo-name>`, NOT\n `~/WORKSPACE` itself).\n2. Verify `CTX_DIR` already points at THIS sub-repo's `.context/`:\n\n ```bash\n test \"$CTX_DIR\" = \"$PWD/.context\" || {\n echo \"STOP: CTX_DIR=$CTX_DIR but this sub-repo needs $PWD/.context.\"\n echo \"Re-launch the agent with CTX_DIR set to the sub-repo:\"\n echo \" cd $PWD && CTX_DIR=\\\"\\$PWD/.context\\\" claude --print 'Follow .arch-explorer/PROMPT.md' --allowedTools '*'\"\n exit 1\n }\n ```\n\n If it fails, STOP. The agent cannot change `CTX_DIR` for itself:\n child shells and skill invocations inherit the parent Claude\n process environment, which only the caller can control. Do not\n proceed, do not run `ctx` commands, do not skip the check.\n3. If phase is `bootstrap`:\n - Run `ctx init`, confirm `.context/` exists.\n - Then run `/ctx-architecture` (structural baseline).\n4. If phase is `principal` or `frontier-*`:\n - Run `/ctx-architecture` (add `principal` argument for principal phase).\n - The skill will read existing artifacts and build on them.\n5. If phase is `enriched`:\n - Verify GitNexus is connected: call `mcp__gitnexus__list_repos`.\n - Success = non-empty list returned with no error.\n - If GitNexus unavailable, log as `enriched-skipped` and advance\n to `frontier-1`.\n - Run `/ctx-architecture-enrich`.\n6. If phase is a lens run (`lens-security`, etc.):\n - Run `/ctx-architecture` with lens focus prepended as instruction\n (see lens table above for exact wording).\n\n### Step 4: Extract Results\n\nAfter the skill completes, gather:\n\n- **Convergence score**: from `map-tracking.json`, computed as:\n average of all module `confidence` values (0.0-1.0). If\n `map-tracking.json` is missing or has no confidence values,\n record `null` and log a warning.\n- **Frontier count**: from CONVERGENCE-REPORT.md, count the number\n of listed unexplored areas. If CONVERGENCE-REPORT.md is missing,\n record `frontier_count: null` and log a warning. Treat missing\n as \"exploration should continue\" (do not stall).\n- **Key findings**: 2-3 bullet points of what was discovered or\n changed in this run (new modules mapped, danger zones found, etc.)\n- **New artifacts**: list any new files created in `.context/`\n\n### Step 5: Update Tracking\n\nUpdate `.arch-explorer/manifest.json`:\n\n```json\n{\n \"progress\": {\n \"ctx\": {\n \"phases_completed\": [\"bootstrap\", \"principal\"],\n \"current_phase\": \"enriched\",\n \"lenses_explored\": [],\n \"last_run\": \"2026-04-07T14:00:00Z\",\n \"convergence_score\": 0.72,\n \"frontier_count\": 3,\n \"total_runs\": 2,\n \"findings_summary\": \"14 modules mapped, 3 danger zones, 2 extension points\"\n }\n }\n}\n```\n\nAppend to `.arch-explorer/run-log.md`:\n\n```markdown\n## 2026-04-07T14:00:00Z / ctx / principal\n\n**Phase:** principal\n**Convergence:** 0.45 -> 0.72\n**Frontiers remaining:** 3\n**Key findings:**\n- Identified CLI dispatch as primary bottleneck (fan-out to 12 subsystems)\n- Security: context files readable by any process (no access control)\n- Strategic recommendation: extract context engine into library package\n\n**Artifacts updated:** ARCHITECTURE-PRINCIPAL.md, DANGER-ZONES.md, map-tracking.json\n```\n\n### Step 6: Report and Stop\n\nPrint this exact format as the FINAL output of the invocation:\n\n```\n[arch-explorer] DONE\n repo: ctx\n phase: principal\n convergence: 0.72\n frontiers: 3\n runs_on_repo: 3\n next: ctx / enriched\n```\n\nThe `[arch-explorer] DONE` line is the terminal marker. After printing\nit, produce no further output. Execution is complete.\n\n## Rules\n\n1. **One unit per invocation.** The only composite unit is `bootstrap`\n (init + structural). All other phases are exactly one skill run.\n2. **Additive only.** Never delete or overwrite existing artifacts.\n The skills already handle incremental updates.\n3. **No duplicated work.** Read manifest before acting. If a phase is\n already recorded as completed, skip it.\n4. **Log everything.** Every run gets a run-log entry, even failures\n and skips.\n5. **Fail gracefully.** If a skill fails (missing GitNexus, broken repo,\n etc.), log the failure with reason and advance to the next phase or\n repo. Don't retry in the same invocation.\n6. **Respect ctx conventions.** Each repo gets its own `.context/`\n directory. Never write architecture artifacts outside `.context/`.\n\n## Stopping Logic\n\nA repo is considered \"explored\" when ANY of these is true:\n- Convergence score >= 0.85 (from map-tracking.json)\n- 3+ frontier runs produced no new findings (frontier_count unchanged\n across consecutive runs)\n- All 5 lenses have been applied\n- Convergence score is `null` after 3 attempts (artifacts aren't being\n generated properly; log warning and move on)\n\nWhen a repo is explored, advance `current_repo_index` in the manifest.\n\n## When All Repos Are Done\n\nWhen every repo has reached its stopping condition, print:\n\n```\n[arch-explorer] ALL DONE\n - ctx: 0.92 convergence, 8 runs, 5 lenses\n - portal: 0.87 convergence, 6 runs, 3 lenses\n ...\n```\n

","path":["Operations","Runbooks","Codebase Audit"],"tags":[]},{"location":"operations/runbooks/codebase-audit/#prompt","level":2,"title":"Prompt","text":"I want you to create an agent team to audit this codebase. Save each report as\na separate markdown file under `./ideas/` (or another directory if you prefer).\n\nUse read-only agents (subagent_type: Explore) for all analyses. No code changes.\n\nFor each report, use this structure:\n- Executive Summary (2-3 sentences + severity table)\n- Findings (grouped, with file:line references)\n- Ranked Recommendations (high/medium/low priority)\n- Methodology (what was examined, how)\n\nKeep reports actionable: every finding should suggest a concrete fix or next step.\n\n## Analyses to Run\n\n### 1. Extractable Patterns (session mining)\nSearch session JSONL files, journal entries, and task archives for repetitive\nmulti-step workflows. Count frequency of bash command sequences, slash command\nusage, and recurring user prompts. Identify patterns that could become skills\nor scripts. Cross-reference with existing skills to find coverage gaps.\nOutput: ranked list of automation opportunities with frequency data.\n\n### 2. Documentation Drift (godoc + inline)\nCompare every doc.go against its package's actual exports and behavior. Check\ninline godoc comments on exported functions against their implementations.\nScan for stale TODO/FIXME/HACK comments. Check package-level comments match\npackage names. Output: drift items ranked by severity with exact file:line refs.\n\n### 3. Maintainability\nLook for: functions >80 lines that have logical split points; switch blocks\nwith >5 cases that could be table-driven or extracted; inline comments that\nsay \"step 1\", \"step 2\" or similar (sign the block wants to be a function);\nfiles with >400 lines; packages with flat structure that could benefit from\nsub-packages; functions that seem misplaced in their file. Do NOT flag\nthings that are fine as-is just because they could theoretically be different.\nOutput: concrete refactoring suggestions, not style nitpicks.\n\n### 4. Security Review\nThis is a CLI app: focus on CLI-relevant attack surface, not web OWASP:\nfile path traversal (does user input flow into file paths unsanitized?),\ncommand injection (does user input flow into exec calls?), symlink following\n(does the tool follow symlinks when writing to .context/?), permission\nhandling (are file permissions set correctly?), sensitive data in outputs\n(do any commands leak secrets or session content?). Output: findings with\nseverity ratings and exploit scenarios.\n\n### 5. Blog Theme Discovery\nRead existing blog posts for style and narrative voice. Analyze git log,\nrecent session discussions, and DECISIONS.md for story arcs worth writing\nabout. Suggest 3-5 blog post themes with: title, angle, target audience,\nkey commits/sessions to reference, and a 2-sentence pitch. Prioritize\nthemes that build a coherent narrative across posts.\n\n### 6. Roadmap & Value Opportunities\nBased on current features, recent momentum, and gaps found in other analyses:\nwhat are the highest-value improvements? Consider: user-facing features,\ndeveloper experience, integration opportunities, and low-hanging fruit.\nOutput: prioritized list with effort/impact estimates (not time estimates).\n\n### 7. User-Facing Documentation\nEvaluate README, help text, and any user docs. Suggest improvements\nstructured as use-case pages: the problem, how ctx solves it, typical\nworkflow, gotchas. Identify gaps where a user would get stuck without\nreading source code. Output: list of documentation gaps and suggested\npage outlines.\n\n### 8. Agent Team Strategies\nBased on the codebase structure, suggest 2-3 agent team configurations for\nupcoming work sessions. For each: team composition (roles, agent types),\ntask distribution strategy, coordination approach, and which types of work\nit suits. Ground suggestions in actual project patterns, not generic advice.\n

Clean state matters: the prompt says \"no code changes\" but accidents happen. Start from a clean git state so you can git checkout . if needed.

Adjust scope: drop analyses you don't need. Analyses 1-4 are the most actionable. Analyses 5-8 are planning/creative and can be skipped if you just want a technical audit.

Weak Dangling Pages\n\nPages that are thin, isolated, or redundant. Signs:\n- Under ~300 words with no unique content (just restates what another page says)\n- Zero or one inbound links (orphaned in the nav)\n- Content that would be stronger merged into an adjacent page\n- \"Try it in 5 minutes\" sections that assume installation already happened\n- Pages whose title doesn't work as a nav entry (too long, too vague)\n\nFor each: identify the page, explain why it's weak, and recommend\nmerge target or deletion.\n\n## 2. Overly Heavy Pages\n\nPages doing too much. Signs:\n- Over ~1500 words with multiple distinct topics\n- More than 4 H2 sections that could stand alone\n- Reader has to scroll past irrelevant content to find what they need\n- Mixed audience (beginner setup + advanced config on same page)\n\nFor each: identify the page, list the distinct topics, and suggest\nsplit points.\n\n## 3. Missing Cross-Links\n\nPlaces where a reader would naturally want to jump to related content\nbut no link exists.

Narrative Gaps\n\nThe docs should tell a coherent story: problem -> install -> first session\n-> daily workflow -> advanced patterns -> contributing. Look for:\n- Gaps in the progression (e.g., no bridge from \"first session\" to\n \"daily habits\")\n- Blog posts that introduce concepts the reference docs don't cover\n- Recipes that assume knowledge no other page teaches\n- Features documented in CLI reference but missing from workflows/recipes\n\nFor each: describe the gap and suggest what page or section would fill it.\n\n## 5. Blog Cross-Linking Opportunities\n\nBlog posts are often written in isolation. Look for:\n- Posts that cover the same theme but don't reference each other\n- Posts that describe the evolution of a feature (natural \"part 1 / part 2\")\n- Posts that would benefit from a \"Related posts\" footer\n- Thematic clusters that could be linked from a recipe or reference page\n\nFor each: list the posts, the shared theme, and the suggested links.\n\n## Output Format\n\nFor every finding, include:\n- File path (docs/whatever.md)\n- Severity: high (actively confusing), medium (missed opportunity),\n low (nice to have)\n- Concrete recommendation (merge into X, split at H2 Y, add link to Z)\n\nEnd with a prioritized action list: what to fix first.\n

Do Not Skip This Section
This is not optional hardening:
An unattended agent with unrestricted OS access is an unattended shell with unrestricted OS access.
The allowlist above is a strong first layer, but do not rely on a single runtime boundary.
For unattended runs, enforce isolation at the infrastructure level:
Layer What to enforce User account Run the agent as a dedicated unprivileged user with no sudo access and no membership in privileged groups (docker, wheel, adm). Filesystem Restrict the project directory via POSIX permissions or ACLs. The agent should have no access to other users' files or system directories. Container Run inside a Docker/Podman sandbox. Mount only the project directory. Drop capabilities (--cap-drop=ALL). Disable network if not needed (--network=none). Never mount the Docker socket and do not run privileged containers. Prefer rootless containers. Virtual machine Prefer a dedicated VM with no shared folders, no host passthrough, and no keys to other machines. Network If the agent does not need the internet, disable outbound access entirely. If it does, restrict to specific domains via firewall rules. Resource limits Apply CPU, memory, and disk limits (cgroups/container limits). A runaway loop should not fill disk or consume all RAM. Self-modification Make instruction files read-only. CLAUDE.md, .claude/settings.local.json, and .context/CONSTITUTION.md should not be writable by the agent user. If using project-local hooks, protect those too. A minimal Docker setup for overnight runs:
docker run --rm \\\n --network=none \\\n --cap-drop=ALL \\\n --memory=4g \\\n --cpus=2 \\\n -v /path/to/project:/workspace \\\n -w /workspace \\\n your-dev-image \\\n ./loop.sh 2>&1 | tee /tmp/loop.log\n
Defense in Depth
Use multiple layers together: OS-level isolation (the boundary the agent cannot cross), a permission allowlist (what Claude Code will do within that boundary), and CONSTITUTION.md (a soft nudge for the common case).

The generated script reads .context/loop.md, runs the tool, checks for completion signals, and loops until done or the cap is reached.
You can also use the /ctx-loop skill from inside Claude Code.
A Shell Loop Is the Best Practice
The shell loop approach spawns a fresh AI process each iteration, so the only state that carries between iterations is what lives in .context/ and git.
Claude Code's built-in /loop runs iterations within the same session, which can allow context window state to leak between iterations. This can be convenient for short runs, but it is less reliable for unattended loops.

Your Questions Reinforce the Pattern
Asking \"is our context clean?\" does two things:
- It triggers a drift check right now
- It reinforces the habit
This is reinforcement, not enforcement.
Do not wait for the agent to be proactive on its own:
Guide your agent, especially in early sessions.
Over time, you will ask less and the agent will start offering more.

Is our context clean?\nAnything stale?\nHow healthy are our context files?\n
Or invoke the skill directly:
/ctx-drift\n
The agent performs two layers of analysis:
Layer 1, structural checks (via ctx drift): Dead paths, missing files, completed task counts, constitution violations. Fast and programmatic.
Layer 2, semantic analysis (agent-driven): Does CONVENTIONS.md describe patterns the code no longer follows? Does DECISIONS.md contain entries whose rationale no longer applies? Are there learnings about bugs that are now fixed? This is where the agent adds value the CLI cannot: It reads both context files and source code and compares them.
The agent reports both layers together, explains each finding in plain language, and offers to fix what it can.

Using Claude Code
ctx ships with Claude Code hooks that remind the agent at the right time to take initiative.
Checking context health at the session start, offering to persist learnings before you quit, and flagging drift when it matters. The agent stays proactive without you having to prompt it:
Agent: Good morning. I've loaded the context files. A few things\n before we start:\n\n - ARCHITECTURE.md references `pkg/auth/` which is now empty\n - DECISIONS.md hasn't been updated in 40 days\n - There are 18 completed tasks ready for archival\n\n Want me to run a quick maintenance pass, or should we jump\n straight into today's work?\n
☝️️ this is what persistent, initiative-driven sessions feel like when context is treated as a system instead of a prompt.
If the agent does not offer this on its own, a gentle nudge is enough:
Anything stale before we start?\nHow's the context looking?\n
This turns maintenance from a scheduled chore into a conversation that happens when it matters.

Agent: ARCHITECTURE.md references `internal/handlers/` but that directory\n doesn't exist. I'll look at the actual source tree to find where\n handlers live now.\n
This happens reliably when the drift intersects the task. What is less reliable is the agent generalizing from one mismatch to \"there might be more stale references; let me run drift detection\" That leap requires the agent to know /ctx-drift exists and to decide the current task should pause for maintenance.
If you want that behavior, reinforce it:
Good catch. Yes, run /ctx-drift and clean up any other stale references.\n

When drift intersects their current task, they will notice: a renamed package, a deleted directory, a path that doesn't resolve. But they rarely generalize from one mismatch to a full audit on their own. Reinforce the pattern: when an agent mentions a stale reference, ask it to run /ctx-drift. Over time, it starts offering.
When an agent says \"this reference looks stale,\" it is usually right.
Semantic drift is more damaging than structural drift: ctx drift catches dead paths. But CONVENTIONS.md describing a pattern your code stopped following three weeks ago is worse. When you ask \"is our context clean?\", the agent can do both checks.
Use ctx status as a quick check: It shows file counts, token estimates, and drift warnings in a single glance. Good for a fast \"is everything ok?\" before diving into work.
Drift detection in CI: add ctx drift --json to your CI pipeline and fail on exit code 3 (violations). This catches constitution-level problems before they reach upstream.
Do not over-compact: Completed tasks have historical value. The --archive flag preserves them in .context/archive/ so you can search past work without cluttering active context.
Sync is cautious by default: Use --dry-run after large refactors, then apply.

By default, they live in .context/ inside the project tree, and that works well when the context can be public.
But sometimes you need the context outside the project:
- Open-source projects with private context: Your architectural notes, internal task lists, and scratchpad entries shouldn't ship with the public repo.
- Compliance or IP concerns: Context files reference sensitive design rationale that belongs in a separate access-controlled repository.
- Personal preference: You want to keep notes separate from code.
ctx supports this by letting you point CTX_DIR anywhere. This recipe shows how to set that up and how to tell your AI assistant where to find the context.
One .context/ per project
The parent of the context directory is the project root by contract. ctx sync, ctx drift, and the memory-drift hook all read the codebase at filepath.Dir(ContextDir()). Pointing two projects at the same directory corrupts their journals, state, and secrets. To share knowledge (CONSTITUTION / CONVENTIONS / ARCHITECTURE) across projects, use ctx hub, not a shared .context/.

Operation Behavior with external .context/ ctx status, agent, add ✅ Works. Operates on files inside CTX_DIR. Journal, scratchpad, hub ✅ Works. Same reason. ctx sync ⚠️ Scans the context repo, not the code repo. ctx drift ⚠️ Same. Reports nothing useful.

The basename guard is permissive about symlinks: it checks the declared name, not the resolved target, so a .context symlink pointing anywhere is accepted as long as the declared basename is .context.

$ ctx system bootstrap\nctx system bootstrap\n====================\n\ncontext_dir: /home/user/repos/myproject-context/.context\n\nFiles:\n CONSTITUTION.md, TASKS.md, DECISIONS.md, ...\n
The CLAUDE.md template generated by ctx init already instructs the agent to run ctx system bootstrap at session start. Because CTX_DIR is inherited by child processes, your agent picks up the external path automatically.
Here is the relevant section from CLAUDE.md for reference:
<!-- CLAUDE.md -->\n1. **Run `ctx system bootstrap`**: CRITICAL, not optional.\n This tells you where the context directory is. If it returns any\n error, relay the error output to the user verbatim, point them at\n https://ctx.ist/recipes/activating-context/ for setup, and STOP.\n Do not try to recover; the user decides.\n
Moreover, every nudge (context checkpoint, persistence reminder, etc.) also includes a Context: /home/user/repos/myproject-context/.context footer, so the agent remains anchored to the correct directory even in long sessions.
Export CTX_DIR in your shell profile so every hook process inherits it:

Your questions train the agent. Asking \"what have we learned?\" or \"is our context clean?\" does two things:
- It triggers the workflow right now,
- and it reinforces the pattern.
The more you guide, the more the agent habituates the behavior and begins offering on its own.
Each recipe includes a Conversational Approach section showing these natural-language patterns.
Tip
Don't wait passively for proactive behavior: especially in early sessions.
Ask, guide, reinforce. Over time, you ask less and the agent offers more.

echo '{\"decision\": \"block\", \"reason\": \"Use ctx from PATH, not ./ctx\"}'\n
When to use: Enforcing invariants that must never be violated: Constitution rules, security boundaries, destructive command prevention.
Hook type: PreToolUse only (Claude Code first-class mechanism).
Examples in ctx:
ctx system block-non-path-ctx: Enforces the PATH invocation rule block-git-push.sh: Requires explicit user approval for pushes (project-local) block-dangerous-commands.sh: Prevents sudo, copies to ~/.local/bin (project-local)
Trade-off: The agent gets a block response with a reason. Good reasons help the agent recover (\"use X instead\"); bad reasons leave it stuck.

When to use: Actionable reminders the user needs to see regardless of what they asked: Stale backups, unimported sessions, resource warnings.
Hook type: UserPromptSubmit (runs before the agent sees the prompt).
Examples in ctx:
ctx system check-journal: Unexported sessions and unenriched entries ctx system check-context-size: Context capacity warning ctx system check-resources: Resource pressure (memory, swap, disk, load): DANGER only ctx system check-freshness: Technology constant staleness warning
Trade-off: Noisy if overused. Every VERBATIM relay adds a preamble before the agent's actual answer. Throttle with once-per-day markers or adaptive frequency.
Key detail: The phrase IMPORTANT: Relay this ... VERBATIM is what makes this work. Without it, agents tend to process the information internally and never surface it. The explicit instruction is the pattern: the box-drawing is just fancy formatting.

When to use: Behavioral nudges. The hook detects a condition and asks the agent to consider an action. The user may never need to know.
Hook type: UserPromptSubmit.
Examples in ctx:
ctx system check-persistence: Nudges the agent to persist context
Trade-off: No guarantee the agent acts. The nudge is one signal among many in the context window. Strong phrasing helps (\"Have you...?\" is better than \"Consider...\"), but ultimately the agent decides.

When to use: Background context loading that should be invisible. The agent benefits from the information, but neither it, nor the user needs to know it happened.
Hook type: PreToolUse with .* matcher (runs on every tool call).
Examples in ctx:
- The
ctx agent PreToolUse hook: injects project context silently

When to use: The hook detects a fixable condition and knows the fix. Goes beyond a nudge: Gives the agent a concrete next step. The agent still asks for permission but knows exactly what to propose.

When to use: When you have multiple hooks producing output and need to avoid overwhelming the user. INFO gets absorbed, WARN gets mentioned, CRITICAL interrupts.
Examples in ctx:
ctx system check-resources: Uses two tiers (WARNING/DANGER) internally but only fires the VERBATIM relay at DANGER level: WARNING is silent. See ctx system for the user-facing command that shows both tiers.

This recipe assumes you've read the ctx Hub overview and the Multi-machine setup. HA only makes sense in the \"small trusted team\" story; a personal cross-project brain on one workstation does not need three Raft peers.
Raft-Lite
ctx uses Raft only for leader election, not for data consensus. Entry replication happens via sequence-based gRPC sync on the append-only JSONL store. This is simpler than full Raft log replication and is possible because the store is append-only and clients are idempotent. The implication: a write accepted by the leader is durable on the leader immediately; followers catch up asynchronously. If the leader crashes between accepting a write and replicating it, that write can be lost. Do not use the hub as a bank ledger.

Subscribe to task only if you want cross-project todos. The four subscribable types are decision, learning, convention, task. Tasks are usually project-local; subscribing makes every hub-shared task from every project show up in every other project's agent packet. That's probably not what you want. Skip task in ctx connection subscribe unless you have a specific reason.
Run the hub as a user-level daemon so you don't have to remember to start it. On Linux with systemd:
# ~/.config/systemd/user/ctx-hub.service\n[Unit]\nDescription=ctx Hub (personal)\n\n[Service]\nType=simple\nExecStart=/usr/local/bin/ctx hub start\nRestart=on-failure\n\n[Install]\nWantedBy=default.target\n

Don't overthink subscription filters. For personal use, subscribe every project to all four types at first (or three, if you skip task). Tune later if the context packets get noisy.
Local storage is fine; no TLS needed. The hub runs on localhost. No one else is on the network. Skip the TLS setup from the Multi-machine recipe; it's relevant when the hub is on a LAN host serving multiple workstations, not when it's a personal daemon.

## [2026-03-12] Error message format\nLowercase start, no trailing period, single sentence.\n
He fixes the PR. No lookup on the wiki, no question in chat, no context-switch penalty.

The team lead or platform engineer should be the person who explicitly --shares cross-cutting decisions. Other team members share learnings freely but should ask \"should this be a decision?\" in review before --shareing a decision. This keeps the decision stream signal-rich.
Publish postmortem learnings immediately, not after the meeting. The postmortem itself is a document; the actionable rules that come out of it belong on the hub, and they should land within an hour of the incident. \"Share fast, edit later\" is the rule.
Delete noisy entries, don't tolerate them. The hub is append-only, but the .context/hub/ mirror on each client is just markdown. If a shared learning turns out to be wrong or obsolete, remove it from local mirrors and stop the hub daemon to truncate entries.jsonl (see Hub operations). Noisy shared feeds lose trust fast.
Don't subscribe every project to every type. For backend engineers, subscribing to decision + learning + convention is usually right. For platform or DevOps projects, adding task makes sense. For a prototype or experiment project, subscribing only to convention might be enough.
Run a single hub, not one per team. If two teams need to share knowledge, they should share a hub. Splitting hubs by team creates silos, which is often exactly the thing you were trying to solve.

The agent was present for the trade-off discussion. It fills in the structured fields from what it observed, which is hard to reconstruct later as a terminal one-liner.
When multiple options were considered, the agent includes rejected alternatives in the rationale automatically.
The /ctx-decision-add skill also guides you through the fields interactively. For quick decisions, it supports a Y-statement:

You said one sentence. The agent produced a structured entry with all three fields filled from the session context.

/ctx-reflect is not the only way to trigger reflection.
Agents trained on the ctx playbook naturally surface persist-worthy items at breakpoints, even without invoking the skill explicitly.
A conversational prompt like \"anything worth saving?\" or \"let's wrap up\" can trigger the same review.
The skill provides a structured checklist, but the behavior is available through natural conversation.
At natural breakpoints (after completing a feature, fixing a bug, or before ending a session) use /ctx-reflect to identify items worth persisting.
/ctx-reflect\n
The skill walks through learnings, decisions, tasks, and session notes, skipping categories with nothing to report. The output includes specific commands for each suggested persist:
This session implemented file-based cooldown for `ctx agent` and\ndiscovered that hook subprocesses cannot set env vars in the parent.\n\nI'd suggest persisting:\n- **Learning**: Hook subprocesses cannot propagate env vars\n `ctx learning add \"...\" --context \"...\" --lesson \"...\" --application \"...\" --session-id abc12345 --branch main --commit 68fbc00a`\n- **Decision**: File-based cooldown tokens over env vars\n `ctx decision add \"...\" --context \"...\" --rationale \"...\" --consequence \"...\" --session-id abc12345 --branch main --commit 68fbc00a`\n\nWant me to persist any of these?\n

You ask, the agent acts:
You say What the agent does \"What have we learned this session?\" Reviews recent work, identifies learnings, offers to persist \"Save that as a decision\" Captures the trade-off you just discussed with structured fields \"Any gotchas worth remembering?\" Scans recent work for non-obvious lessons \"Record that convention\" Adds the pattern you just agreed on to CONVENTIONS.md \"Let's wrap up\" Runs through the reflect checklist conversationally Example exchange:
You: \"What did we learn from that debugging session?\"\n\nAgent: \"We discovered three things worth persisting:\n 1. Hook subprocesses can't propagate env vars to the parent.

The cooldown logic must check file mtime, not just existence.\n Want me to save these as learnings?\"\n\nYou: \"Yes, all of them.\"\n\nAgent: \"Done. Added all three to LEARNINGS.md with structured fields.\"\n
The agent can also be proactive without being asked. The playbook encourages agents to persist context at natural milestones.
You may see:
- After fixing a tricky bug: \"I noticed this was a non-obvious issue. Want me to save it as a learning?\"
- After choosing between approaches: \"We just made a trade-off between file-based tokens and IPC. Should I record this as a decision?\"
- At session milestones: the agent checks what is worth persisting and offers a brief summary.
When agents run unattended (no human in the loop), they may persist directly:
- \"I've added the subprocess env var gotcha to
LEARNINGS.md so we don't hit it again.\" - \"Recorded the decision to use file-based tokens over env vars in
DECISIONS.md.\" - \"Marked the cooldown task done and added a follow-up for TTL cleanup.\"
This is behavior by design.
The playbook's self-check prompt, \"If this session ended right now, would the next session know what happened?\" drives agents to persist early and often rather than waiting for explicit instructions.

- Use
/ctx-reflect at natural breakpoints. The checklist catches items you might otherwise lose. - Keep the entries self-contained. Each entry should make sense on its own. A future session may load only one due to token budget constraints.
- Reindex after every hand edit. It takes less than a second. A stale index causes AI tools to miss entries.
- Prefer the structured fields. The verbosity forces clarity. A decision without a rationale is just a fact. A learning without an application is just a story.
- Talk to your agent, do not type commands. In interactive sessions, the conversational approach is the recommended way to capture knowledge. Say \"save that as a learning\" or \"any decisions worth recording?\" and let the agent handle the structured fields. Reserve the CLI commands for scripting, automation, and CI/CD pipelines where there is no agent in the loop.
- Trust the agent's proactive instincts. Agents trained on the
ctx playbook will offer to persist context at milestones. A brief \"want me to save this?\" is cheaper than re-discovering the same lesson three sessions later. -
Relax provenance per-project if --session-id, --branch, or --commit are impractical (e.g., manual notes outside an AI session). Add to .ctxrc:
provenance_required:\n session_id: false # allow entries without --session-id\n branch: true # still require --branch\n commit: true # still require --commit\n
Default is all three required. Only human config relaxes: Agents cannot bypass, and that's by design.

Using a Different .context Directory
The .context/ directory doesn't have to live inside your project. Point ctx to an external folder by exporting CTX_DIR (the only declaration channel).
Useful when context must stay private while the code is public, or when you want to commit notes to a separate repo.
Caveats (the recipe covers both with workarounds):
- Code-aware operations degrade silently.
ctx sync, ctx drift, and the memory-drift hook read the codebase from dirname(CTX_DIR). With an external .context/, that's the context repo, not your code repo. They scan the wrong tree without erroring. The recipe shows a symlink workaround that keeps both healthy. - One
.context/ per project, always. Sharing one directory across multiple projects corrupts journals, state, and secrets. For cross-project knowledge sharing (CONSTITUTION, CONVENTIONS, ARCHITECTURE, etc.) use ctx hub, not a shared .context/.
See External Context for the full recipe and Configuration for the resolver details.
For Claude Code, install the ctx plugin to get hooks and skills:
claude /plugin marketplace add ActiveMemory/ctx\nclaude /plugin install ctx@activememory-ctx\n
If you only need the core files (useful for lightweight setups), use the --minimal flag:
ctx init --minimal\n

\"Do you remember?\"
A correctly configured tool responds with specific context: current tasks from TASKS.md, recent decisions, and previous session topics. It should not say \"I don't have memory\" or \"Let me search for files.\"
This question checks the passive side of memory. A properly set-up agent is also proactive: it treats context maintenance as part of its job:
- After a debugging session, it offers to save a learning.
- After a trade-off discussion, it asks whether to record the decision.
- After completing a task, it suggests follow-up items.
The \"do you remember?\" check verifies both halves: recall and responsibility.
For example, after resolving a tricky bug, a proactive agent might say:
That Redis timeout issue was subtle. Want me to save this as a *learning*\nso we don't hit it again?\n
If you see behavior like this, the setup is working end to end.
In Claude Code, you can also invoke the /ctx-status skill:
/ctx-status\n
This prints a summary of all context files, token counts, and recent activity, confirming that hooks are loading context.

ctx drift periodically to catch stale references before they confuse the agent. - The agent playbook instructs the agent to persist context at natural milestones (completed tasks, decisions, gotchas).

--keep-frontmatter=false discards enriched YAML frontmatter during regeneration.
Back up your journal before using this flag.
Each imported file contains session metadata (date, time, duration, model, project, git branch), a tool usage summary, and the full conversation transcript.
Re-importing is safe. Running ctx journal import --all only imports new sessions: Existing files are never touched. Use --dry-run to preview what would be imported without writing anything.
To re-import existing files (e.g., after a format improvement), use --regenerate: Conversation content is regenerated while preserving any YAML frontmatter you or the enrichment skill has added. You'll be prompted before any files are overwritten.
--regenerate Replaces the Markdown Body
--regenerate preserves YAML frontmatter but replaces the entire Markdown body with freshly generated content from the source JSONL.
If you manually edited the conversation transcript (added notes, redacted sensitive content, restructured sections), those edits will be lost.
BACK UP YOUR JOURNAL FIRST.
To protect entries you've hand-edited, you can explicitly lock them:
ctx journal lock <pattern>\n
Locked entries are always skipped, regardless of flags.
If you prefer to add locked: true directly in frontmatter during enrichment, run ctx journal sync to propagate the lock state to .state.json:
ctx journal sync\n

Locked entries are skipped by enrichment skills, just as they are by import. Lock entries you want to protect before running batch enrichment.
Batch enrichment (recommended):
/ctx-journal-enrich-all\n
The skill finds all unenriched entries, filters out noise (suggestion sessions, very short sessions, multipart continuations), and processes each one by extracting titles, topics, technologies, and summaries from the conversation.
It shows you a grouped summary before applying changes so you can scan quickly rather than reviewing one by one.
For large backlogs (20+ entries), the skill can spawn subagents to process entries in parallel.
Single-entry enrichment:
/ctx-journal-enrich twinkly\n/ctx-journal-enrich 2026-02-06\n

You can also ask your agent to browse sessions conversationally instead of remembering flags:
What did we work on last week?\nShow me the session about Redis.\nImport everything to the journal.\n
This is convenient but not required: ctx journal source gives you the same inventory.
Where the agent genuinely helps is chaining the pipeline:
You: What happened last Tuesday?\nAgent: Last Tuesday you worked on two sessions:\n - bright-dancing-hopper (2h 10m): refactored the middleware\n pipeline and added Redis caching\n - quiet-flowing-dijkstra (18m): quick fix for a nil pointer\n in the config loader\n Want me to export and enrich them?\nYou: Yes, do it.\nAgent: Exports both, enriches, then proposes frontmatter.\n

If the agent only half-loads context at the start, it works from stale assumptions. If it only half-persists at the end, learnings and decisions are lost.

ctx commands (and the skills that call them) require CTX_DIR to be declared for the shell you're working in; ctx does not walk the filesystem to find .context/. Once per shell (or via your shell rc / direnv):
eval \"$(ctx activate)\"\n

What Is a Readback?
A readback is a structured summary where the agent plays back what it knows:
- last session,
- active tasks,
- recent decisions.
This way, you can confirm it loaded the right context.
The term \"readback\" comes from aviation, where pilots repeat instructions back to air traffic control to confirm they heard correctly.
Same idea in ctx: The agent tells you what it \"thinks\" is going on, and you correct anything that's off before the work begins.
- Last session: topic, date, what was accomplished
- Active work: pending and in-progress tasks
- Recent context: 1-2 decisions or learnings that matter now
- Next step: suggestion or question about what to focus on

The readback should feel like a recall, not a file system tour. If you see \"Let me check if there are files...\" instead of a confident summary, the context system is not loaded properly.

- Empty core files:
TASKS.md or CONVENTIONS.md with no content means the context is sparse - High token count (over 30k): the context is bloated and might need
ctx compact - No recent activity: files may be stale and need updating

Use /ctx-implement for multistep plans: if the task has multiple steps, this skill executes them one at a time with build/test verification between each step.
Context monitoring runs automatically: the check-context-size hook monitors context capacity at adaptive intervals. Early in a session it stays silent.

The Agent May Recommend Committing
You do not always need to invoke /ctx-commit explicitly.
After a commit, the agent may proactively offer to capture context:
\"We just made a trade-off there. Want me to record it as a decision?\"
This is normal: The Agent Playbook encourages persisting at milestones, and a commit is a natural milestone.
As an alternative, you can ask the assistant \"can we commit this?\" and it will pick up the /ctx-commit skill for you.
The skill runs a pre-commit build check (for Go projects, go build), reviews the staged changes, drafts a commit message focused on \"why\" rather than \"what\", and then commits.
After the commit succeeds, it prompts you:
**Any context to capture?**\n\n- **Decision**: Did you make a design choice or trade-off?\n- **Learning**: Did you hit a gotcha or discover something?\n- **Neither**: No context to capture; we are done.\n
If you made a decision, the skill records it with ctx decision add. If you learned something, it records it with ctx learning add including context, lesson, and application fields. This is the bridge between committing code and remembering why the code looks the way it does.
If source code changed in areas that affect documentation, the skill also offers to check for doc drift.

Agents Reflect at Milestones
Agents often reflect without explicit invocation.
After completing a significant piece of work, the agent may naturally surface items worth persisting:
\"We discovered that $PPID resolves differently inside hooks. Should I save that as a learning?\"
This is the agent following the Work-Reflect-Persist cycle from the Agent Playbook.
You do not need to say /ctx-reflect for this to happen; the agent treats milestones as reflection triggers on its own.
The skill works through a checklist: learnings discovered, decisions made, tasks completed or created, and whether there are items worth persisting. It then presents a summary with specific items to persist, each with the exact command to run:
I would suggest persisting:\n\n- **Learning**: `$PPID` in PreToolUse hooks resolves to the Claude Code PID\n `ctx learning add --context \"...\" --lesson \"...\" --application \"...\" --session-id abc12345 --branch main --commit 68fbc00a`\n- **Task**: mark \"Add cooldown to ctx agent\" as done\n- **Decision**: tombstone-based cooldown with 10m default\n `ctx decision add \"...\" --session-id abc12345 --branch main --commit 68fbc00a`\n\nWant me to persist any of these?\n
The skill asks before persisting anything. You choose what to keep.

","path":["Recipes","Sessions","The Complete Session"],"tags":[]},{"location":"recipes/session-lifecycle/#conversational-session-flow","level":2,"title":"Conversational Session Flow","text":"The steps above describe the mechanics. In practice, a session with a ctx-aware agent feels more like a conversation than a command sequence.
The agent knows the lifecycle and moves through it naturally, often without explicit invocation. Here is a realistic example:
You: Do you remember what we were working on?
Agent (loads context silently, presents structured readback):
Last session (Feb 7, caching-layer): we implemented the in-memory cache with\nTTL expiration and wrote tests for the eviction policy. \n\nYou have 3 pending tasks; the biggest one is adding Redis as a backend.\n\nRecent decision:<br>\nwe chose LRU over LFU because the access pattern is mostly recency-based.\n\nWant to continue with the Redis backend, or tackle something else?\n
You: Let's work on the Redis caching backend.
Agent (picks up the task, begins implementation):
Got it. I see the task in TASKS.md: \"Add Redis backend for cache layer.\"\n\nI will start with the connection pool setup. Only touching\n`internal/cache/redis/` for now.\n
(The agent works... writes code, runs tests, iterates.)
Agent (after implementing the connection pool and choosing a retry strategy):
The connection pool is working. I went with exponential backoff with jitter\nfor retries instead of fixed intervals; it handles thundering herd better\nunder reconnection storms. That is a design choice worth recording. \n\nWant me to save it as a decision?\n
You: Yes, go ahead.
Agent:
Done. Added to DECISIONS.md: \"Exponential backoff with jitter for Redis\nreconnection, to avoid thundering herd on pool recovery.\"\n
(More work happens... the agent implements the cache read/write paths.)
You: What else did we learn during this session?
Agent:
A few things worth capturing:\n\n* **Learning**: Redis `SET` with `NX` and `PX` flags handles atomic\n set-if-not-exists with TTL in a single call. No need for a separate\n `EXPIRE` command. We initially did it in two calls and hit a race condition.\n* **Learning**: The `go-redis` library's `PoolSize` default is 10 per CPU.\n For our workload, explicit sizing at 20 was more predictable.\n* **Task update**: The connection pool subtask is done; the read/write path\n is implemented but needs integration tests.\n\nWant me to persist these?\n
You: Yes. And let's wrap up.
Agent (reflects and persists... all in one flow):
Persisted:\n\n* 2 learnings added to LEARNINGS.md\n* Marked \"connection pool setup\" done in TASKS.md\n* Added \"write integration tests for Redis cache\" as a new task\n\nContext is up to date. You are good to close.\n
Notice What Happened
In the above workflow, the user never typed /ctx-reflect or ctx learning add.
The agent moved through Load, Orient, Pick, Work, Commit, and Reflect driven by natural conversation.
\"Let's wrap up\" was enough to trigger the full reflect-and-persist flow.
The agent surfaced persist-worthy items at milestones: after a design choice, after discovering a gotcha: without waiting to be asked.
This is the intended experience.
The commands and skills still exist for when you want precise control, but the agent is a proactive partner in the lifecycle, not a passive executor of slash commands.

- Load:
/ctx-remember: load context and confirm readback - Orient:
/ctx-status: check file health and token usage - Pick:
/ctx-next: choose what to work on - Work: implement, test, iterate (scope with \"only change X\")
- Commit:
/ctx-commit: commit and capture decisions/learnings - Reflect:
/ctx-reflect: identify what to persist (at milestones) - Wrap up:
/ctx-wrap-up: end-of-session ceremony
Conversational equivalents: you can drive the same lifecycle with plain language:
Step Slash command Natural language Load /ctx-remember \"Do you remember?\" / \"What were we working on?\" Orient /ctx-status \"How's our context looking?\" Pick /ctx-next \"What should we work on?\" / \"Let's do the caching task\" Work (none) \"Only change files in internal/cache/\" Commit /ctx-commit \"Commit this\" / \"Ship it\" Reflect /ctx-reflect \"What did we learn?\" / (agent offers at milestones) Wrap up /ctx-wrap-up (use the slash command for completeness) The agent understands both columns.
In practice, most sessions use a mix:
- Explicit Commands when you want precision;
- Natural Language when you want flow and agentic autonomy.
The agent will also initiate steps on its own (particularly \"Reflect\") when it recognizes a milestone.
Short sessions (quick bugfix) might only use: Load, Work, Commit.
Long sessions should Reflect after each major milestone and persist learnings and decisions before ending.

A hook monitors context capacity and notifies you when it gets high, but do not wait for the notification. If you have been working for a while and have unpersisted learnings, persist proactively.
Browse previous sessions by topic. If you need context from a prior session, ctx journal source --show auth will match by keyword. You do not need to remember the exact date or slug.
Reflection is optional but valuable. You can skip /ctx-reflect for small changes, but always persist learnings and decisions before ending a session where you did meaningful work. These are what the next session loads.
Let the hook handle context loading. The PreToolUse hook runs ctx agent automatically with a cooldown, so context loads on first tool use without you asking. The /ctx-remember prompt at session start is for your benefit (to get a readback), not because the assistant needs it.
The agent is a proactive partner, not a passive tool. A ctx-aware agent follows the Agent Playbook: it watches for milestones (completed tasks, design decisions, discovered gotchas) and offers to persist them without being asked. If you finish a tricky debugging session, it may say \"That root cause is worth saving as a learning. Want me to record it?\" before you think to ask. This is by design.

Before You Start
If you're unsure whether a rule belongs in steering/, DECISIONS.md, or CONVENTIONS.md, read the \"Steering vs decisions vs conventions\" admonition on the ctx steering reference page. The short version: if the rule is \"the AI should always do X when asked about Y,\" that's steering. Otherwise it's probably a decision or convention.

File Purpose .context/steering/product.md Product context, goals, target users .context/steering/tech.md Tech stack, constraints, key dependencies .context/steering/structure.md Directory layout, naming conventions .context/steering/workflow.md Branch strategy, commit rules, pre-commit Each file opens with an inline HTML comment that explains the three inclusion modes, what priority means, and the tools scope. The comment is invisible in rendered markdown but visible when you edit the file. Delete it once the file is yours.
All four default to inclusion: always and priority: 10, so they fire on every AI tool call until you customize them. If you're reading this recipe and haven't touched them yet, open each one now and replace the placeholder bullet list with actual rules for your project. That's the highest-leverage five minutes you can spend in a new ctx setup.
What to fill in, by file:
product.md: The elevator pitch plus hard scope:
- One-sentence product description.
- Primary users and their top job-to-be-done.
- Two or three \"this is explicitly out of scope\" items so the AI doesn't wander.
tech.md: Technology and constraints:
- Languages and versions (
Go 1.22, Node 20, etc.). - Frameworks and key libraries.
- Runtime and deployment target.
- Hard constraints: \"no CGO\", \"no network at test time\", \"no external DB for unit tests\". These are the things that burn agents when they don't know them.
structure.md: Layout and naming:
- Top-level directories and their purpose.
- Where new files should go (and where they should NOT).
- Naming conventions for packages, files, types.
workflow.md: Process rules:
- Branch strategy (main-only, trunk-based, feature branches).
- Commit message format, signed-off-by requirement.
- Pre-commit and pre-push checks.
- Review expectations.
After editing, the next AI tool call in Claude Code will pick up the new rules automatically via the plugin's PreToolUse hook, with no sync step and no restart. Other tools (Cursor, Cline, Kiro) need ctx steering sync to export into their native format.
Prefer a Bare .context/steering/ Directory?
Re-run ctx init --no-steering-init and delete the scaffolded files. ctx init leaves existing files alone, so the flag is only needed if you want to opt out of the initial scaffold.

Claude Code Users: Pick always, Not auto
This walkthrough uses inclusion: auto because the scenario is a scoped rule that matches a specific kind of prompt. That works natively on Cursor, Cline, and Kiro (they resolve the description keyword match themselves).
On Claude Code, auto does not fire through the plugin's PreToolUse hook. The hook passes an empty prompt to ctx agent, so only always files match. Claude can still reach an auto file by calling the ctx_steering_get MCP tool, but that requires Claude to decide to call it; there's no automatic injection.
If Claude Code is your tool, set inclusion: always in Step 2 instead of auto. The rule will fire on every tool call regardless of topic. You may want to narrow the rule body so the extra tokens per turn aren't wasted on unrelated work.
See the ctx steering reference \"Prefer inclusion: always for Claude Code\" section for the full trade-off.

Instead, steering reaches these tools through two non-sync channels:
-
PreToolUse hook (automatic). The ctx setup claude-code plugin installs a hook that runs ctx agent --budget 8000 before each tool call. ctx agent loads your steering files, filters them against the active prompt, and includes matching bodies as Tier 6 of the context packet. The packet gets injected into Claude's context automatically.
-
ctx_steering_get MCP tool (on-demand). Claude can call this MCP tool mid-task to fetch matching steering files for a specific prompt. Automatic activation comes from Claude's judgment, not a hook.
Both channels activate when you run:
ctx setup claude-code --write\n
That installs the plugin, wires the hook, and registers the MCP server. After that, steering files you edit are picked up on the next tool call, with no sync step needed.
Running ctx steering sync with Claude Code
It won't error; it will simply report that Claude and Codex aren't sync targets and skip them. If Claude Code is your only tool, you never need to run sync. If you use both Claude Code and (say) Cursor, run sync to keep Cursor up to date; the Claude pipeline takes care of itself via the hook.

If nothing happens, the fix depends on which path you're on:
Path A (Cursor/Cline/Kiro):
- Re-run
ctx steering preview with the literal prompt to confirm the match. - Run
ctx steering list and verify inclusion is auto, not manual. - Check the tool's own config directory (e.g.
.cursor/rules/); the file should be there after ctx steering sync.
Path B (Claude Code):
- Re-run
ctx steering preview with the literal prompt to confirm the match. - Verify the plugin is installed:

ctx agent --budget 8000 manually and grep the output for your rule body. If it's there, the data is fine; if it's missing, the inclusion mode or description is at fault. - As a last resort, ask Claude directly: \"Call the

When working with an AI agent, use /ctx-task-add instead of raw ctx task add. The agent automatically picks up session ID, branch, and commit hash from its context, so no manual flags are needed.
Activate the Project First
Run eval \"$(ctx activate)\" once per terminal in the project root. If you skip it, the ctx task add / ctx task ... commands below fail with Error: no context directory specified. See Activating a Context Directory.

The /ctx-task-add skill validates your task before recording it. It checks that the description is actionable, not a duplicate, and specific enough for someone else to pick up.
If you say \"fix the bug,\" it will ask you to clarify which bug and where.
Tasks Are Often Created Proactively
In practice, many tasks are created proactively by the agent rather than by explicit CLI commands.
After completing a feature, the agent will often identify follow-up work: tests, docs, edge cases, error handling, and offer to add them as tasks.
You do not need to dictate ctx task add commands; the agent picks up on work context and suggests tasks naturally.

Phases provide logical groupings that preserve order and enable replay.
A task does not move between sections. It stays in its phase permanently, and status is tracked via checkboxes and inline tags.
## Phase 1: Core CLI\n\n- [x] Implement ctx add command\n- [x] Implement ctx task complete command\n- [ ] Add --section flag to ctx task add `#priority:medium`\n\n## Phase 2: AI Integration\n\n- [ ] Implement ctx agent cooldown `#priority:high` `#in-progress`\n- [ ] Add ctx watch XML parsing `#priority:medium`\n - Blocked by: Need to finalize agent output format\n\n## Backlog\n\n- [ ] Performance optimization for large TASKS.md files `#priority:low`\n- [ ] Add metrics dashboard to ctx status `#priority:deferred`\n
Use --section when adding a task to a specific phase:
ctx task add \"Add ctx watch XML parsing\" --priority medium --section \\\n \"Phase 2: AI Integration\" \\\n --session-id abc12345 --branch main --commit 68fbc00a\n
Without --section, the task is inserted before the first unchecked task in TASKS.md.

The output looks like this:

The task's checkbox changes from [ ] to [x]. Tasks are never deleted: they stay in their phase section so history is preserved.
Be Conversational
You rarely need to run ctx task complete yourself during an interactive session.
When you say something like \"the rate limiter is done\" or \"we finished that,\" the agent marks the task complete and moves on to suggesting what is next.
The CLI commands are most useful for manual housekeeping, scripted workflows, or when you want precision.

This creates a file like .context/archive/tasks-before-refactor-2026-02-08-1430.md. If the refactor goes sideways, and you need to confirm what the task state looked like before you started, the snapshot is there.
Snapshots are cheap: Take them before any change you might want to undo or review later.

Then archive:

Completed tasks move to .context/archive/tasks-2026-02-08.md. Phase headers are preserved in the archive for traceability. Pending tasks ([ ]) remain in TASKS.md.

Document the rate limit configuration in the ops runbook\n\nWant me to add these as tasks?\"\n
This is how an agent behaves once it has read the Agent Playbook.
The playbook's \"Work, Reflect, Persist\" cycle means the agent asks itself after every milestone: Did I just complete a task? Did new work emerge?
When the answer is yes, it acts.

Instead of reviewing the session yourself and typing specific commands, ask the agent to do the thinking:
You say What happens \"What tasks came out of this session?\" Agent reviews the work, identifies follow-ups, and offers to add them \"Are there any tasks, learnings, or decisions worth adding?\" Agent scans the full session for all three types and proposes a batch \"What should we remember from today?\" Agent surfaces everything persist-worthy: not just tasks \"Anything we should track before we move on?\" Agent checks for loose ends specific to the work just completed This is especially powerful after long or exploratory sessions where multiple threads were touched.
The agent has the full conversation in context and can spot follow-ups you might miss:
You: \"Are there any tasks, learnings, or decisions worth adding\n from this session?\"\n\nAgent: \"Yes. Here's what I'd suggest:\n\n Tasks:\n - Add retry logic to the webhook delivery (we discussed it when\n the timeout test failed but never tracked it)\n - Update the API docs to reflect the new rate limit headers\n\n Learnings:\n - net/http's default client has no timeout: we burned 15 minutes\n on that before adding an explicit 30s timeout\n\n Decisions:\n - We chose token-bucket over sliding-window for rate limiting\n because it handles bursts better and the library is simpler\n\n Want me to add all of these?\"\n\nYou: \"All of them.\"\n

- Use
#in-progress sparingly. Only one or two tasks should carry this tag at a time. If everything is in-progress, nothing is. - Snapshot before, not after. The point of a snapshot is to capture the state before a change, not to celebrate what you just finished.
- Archive regularly. Once completed tasks outnumber pending ones, it is time to archive. A clean
TASKS.md helps both you and your AI assistant focus. - Never delete tasks. Mark them
[x] (completed) or [-] (skipped with a reason). Deletion breaks the audit trail. - Trust the agent's task instincts. When the agent suggests follow-up items after completing work, it is drawing on the full context of what just happened.
- Conversational prompts beat commands in interactive sessions. Saying \"what should we work on?\" is faster and more natural than running
/ctx-next. Save explicit commands for scripts, CI, and unattended runs. - Let the agent chain operations. A single statement like \"that's done, what's next?\" can trigger completion, follow-up identification, and next-task selection in one flow.
- Review proactive task suggestions before moving on. The best follow-ups come from items spotted in-context right after the work completes.

Triggers Execute Arbitrary Code
A trigger is a shell script with the executable bit set. It runs with the same privileges as your AI tool and receives JSON input on stdin. Treat triggers like pre-commit hooks:
- Only enable scripts you have read and understand.
- Never enable a trigger you downloaded from the internet without reviewing every line.
- Avoid shelling out to user-controlled values (
jq -r output, path field, tool field) without quoting. - A malicious or buggy trigger can block tool calls, corrupt context files, or exfiltrate data.
The generated trigger template starts disabled (no executable bit) so you cannot accidentally run an unreviewed script. Enable it explicitly with ctx trigger enable.

allow case: the default is allow. An empty or missing response is a risky default. - Use

ctx as the shared brain: Whether it's one agent or four, the .context/ directory is the single source of truth. Decisions go in DECISIONS.md, not in chat messages between agents. - Merge early, merge often: Long-lived parallel branches diverge. Merge a track as soon as it's done rather than waiting for all tracks to finish.
TASKS.md conflicts are normal: Multiple agents completing different tasks will conflict on merge. The resolution is always additive: accept all [x] completions from both sides.

Without persistent context, agents tend to:
- rediscover decisions
- repeat mistakes
- lose architectural intent
This is why ctx pairs well with autonomous loop workflows:
- The loop provides iteration
ctx provides continuity
Together, loops become cumulative instead of forgetful.

- centralized context services
- dashboards
- access control
- organizational knowledge layers
These tools are designed for:
- teams
- governance
- compliance
- managed environments
ctx is intentionally:
- local-first: context lives next to your code, not behind a service boundary.
- file-based: everything important is a markdown file you can read, diff, grep, and version-control.
- single-binary core: the context persistence path (
init, add, agent, status, drift, load, sync, compact, task, decision, learning, and their siblings) is a single Go binary with no required runtime dependencies. Optional integrations (ctx trace (needs git), ctx serve (needs zensical), the ctx Hub (needs a running hub), Claude Code plugin (needs claude)) are opt-in and each declares its dependency explicitly. - CLI-driven: every feature is reachable from the command line and scriptable.
- developer-controlled: no auto-updating cloud service, no telemetry, no account to sign up for.
The core ctx binary does not require:
- a server
- a database
- an account
- a SaaS backend
- network connectivity (for core operations)
ctx optimizes for individual and small-team workflows where context should live next to code; not behind a service boundary.

Auto-memory is convenient - you do not configure anything. But it is also opaque: you cannot see what was stored, edit it precisely, or share it across tools. ctx files are plain Markdown in your repository, visible in diffs and code review.
The two are complementary. ctx can absorb auto-memory as an input source (importing what the model remembered into structured context files) while providing the durable, inspectable layer that auto-memory lacks.

For Claude Code, ctx init writes both an allowlist and an explicit deny list into .claude/settings.local.json. The golden images live in internal/assets/permissions/:
Allowlist (allow.txt): only these tools run without confirmation:
Bash(ctx:*)\nSkill(ctx-convention-add)\nSkill(ctx-decision-add)\n... # all bundled ctx-* skills\n
Deny list (deny.txt): these are blocked even if the agent requests them:
# Dangerous operations\nBash(sudo *)\nBash(git push *)\nBash(git push)\nBash(rm -rf /*)\nBash(rm -rf ~*)\nBash(curl *)\nBash(wget *)\nBash(chmod 777 *)\n\n# Sensitive file reads\nRead(**/.env)\nRead(**/.env.*)\nRead(**/*credentials*)\nRead(**/*secret*)\nRead(**/*.pem)\nRead(**/*.key)\n\n# Sensitive file edits\nEdit(**/.env)\nEdit(**/.env.*)\n
What it catches: The agent cannot run commands outside the allowlist, and the deny list blocks dangerous operations even if a future allowlist change were to widen access. If rm, curl, sudo, or docker are not allowed and sudo/curl/wget are explicitly denied, the agent cannot invoke them regardless of what any prompt says.
What it misses: The agent can modify the allowlist itself. In an autonomous loop, if the agent writes to .claude/settings.local.json, and the next iteration loads the modified config, then the protection is effectively lost. The application enforces the rules, but the application reads the rules from files the agent can write.

A log that silently drops entries while the rest of the system claims success is worse than no log at all: operators see a green TUI and a webhook notification and conclude \"it happened,\" even when the audit trail never landed.

","path":["The Thesis"],"tags":[]},{"location":"thesis/#abstract","level":3,"title":"Abstract","text":"As AI tools evolve from code-completion utilities into reasoning collaborators, the knowledge that governs their behavior becomes as important as the code they produce; yet, that knowledge is routinely discarded at the end of every session.
AI-assisted development systems assemble context at prompt time using heuristic retrieval from mutable sources: recent files, semantic search results, session history. These approaches optimize relevance at the moment of generation but do not persist the cognitive state that produced decisions. Reasoning is not reproducible, intent is lost across sessions, and teams cannot audit the knowledge that constrains automated behavior.
This paper argues that context should be treated as deterministic, version-controlled state rather than as a transient query result. We ground this argument in three sources of evidence: a landscape analysis of 17 systems spanning AI coding assistants, agent frameworks, and knowledge stores; a taxonomy of five primitive categories that reveals irrecoverable architectural trade-offs; and an experience report from ctx, a persistence layer for AI-assisted development, which developed itself using its own persistence model across 389 sessions over 33 days. We define a three-tier model for cognitive state: authoritative knowledge, delivery views, and ephemeral state. Then we present six design invariants empirically validated by 56 independent rejection decisions observed across the analyzed landscape. We show that context determinism applies to assembly, not to model output, and that the curation cost this model requires is offset by compounding returns in reproducibility, auditability, and team cognition.
","path":["The Thesis"],"tags":[]},{"location":"thesis/#1-introduction","level":2,"title":"1. Introduction","text":"The introduction of large language models into software development has shifted the primary interface from code execution to interactive reasoning. In this environment, the correctness of an output depends not only on source code but on the context supplied to the model: the conventions, decisions, architectural constraints, and domain knowledge that bound the space of acceptable responses.
Current systems treat context as a query result assembled at the moment of interaction. A developer begins a session; the tool retrieves what it estimates to be relevant from chat history, recent files, and vector stores; the model generates output conditioned on this transient assembly; the session ends, and the context evaporates. The next session begins the cycle again.
This model has improved substantially over the past year. CLAUDE.md files, Cursor rules, Copilot's memory system, and tools such as Mem0, Letta, and Kindex each address aspects of the persistence problem. Yet across 17 systems we analyzed spanning AI coding assistants, agent frameworks, autonomous coding agents, and purpose-built knowledge stores, no system provides all five of the following properties simultaneously: deterministic context assembly, human-readable file-based persistence, token-budgeted delivery, a single-binary core with zero required runtime dependencies for the persistence path, and local-first operation.
This paper does not propose a universal replacement for retrieval-centric workflows. It defines a persistence layer (embodied in ctx (https://ctx.ist)) whose advantages emerge under specific operational conditions: when reproducibility is a requirement, when knowledge must outlive sessions and individuals, when teams require shared cognitive authority, or when offline operation is necessary.
The trade-offs (manual curation cost, reduced automatic recall, coarser granularity) are intentional and mirror the trade-offs accepted by systems that favor reproducibility over convenience, such as reproducible builds and immutable infrastructure 1 6.
The contribution is threefold: a three-tier model for cognitive state that resolves the ambiguity between authoritative knowledge and ephemeral session artifacts; six design invariants empirically grounded in a cross-system landscape analysis; and an experience report demonstrating that the model produces compounding returns when applied to its own development.

Reproducibility (the ability to reconstruct the exact inputs that produced a given output) is a foundational property of reliable systems. Its loss in AI-assisted development mirrors the historical evolution from ad-hoc builds to deterministic build systems 1 2. The build community learned that when outputs depend on implicit state (environment variables, system clocks, network-fetched dependencies), debugging becomes archaeology. The same principle applies when AI outputs depend on non-deterministic context retrieval.

When a vector store determines that a code snippet is \"similar\" to the current query, the ranking function is opaque: the developer cannot inspect why that snippet was chosen, whether a more relevant artifact was excluded, or whether the ranking will remain stable. This prevents deterministic debugging, policy auditing, and causal attribution (properties that information retrieval theory identifies as fundamental trade-offs of probabilistic ranking) 3.
In practice, this opacity manifests as a compliance ceiling. In our experience developing a context management system (detailed in Section 7), soft instructions (directives that ask an AI agent to read specific files or follow specific procedures) achieve approximately 75-85% compliance. The remaining 15-25% represents cases where the agent exercises judgment about whether the instruction applies, effectively applying a second ranking function on top of the explicit directive. When 100% compliance is required, instruction is insufficient; the content must be injected directly, removing the agent's option to skip it.

Cognitive State: A Three-Tier Model","text":"","path":["The Thesis"],"tags":[]},{"location":"thesis/#31-definitions","level":3,"title":"3.1 Definitions","text":"We define cognitive state as the authoritative, persistent representation of the knowledge required for correct decision-making within a project. It is human-authored or human-ratified, versioned, inspectable, and reproducible. It is distinct from logs, transcripts, retrieval results, and model-generated summaries.
Previous formulations of this idea have treated cognitive state as a monolithic concept. In practice, a three-tier model better captures the operational reality:
Tier 1: Authoritative State: The canonical knowledge that the system treats as ground truth. In a concrete implementation, this corresponds to a set of human-curated files with defined schemas: a constitution (inviolable rules), conventions (code patterns), an architecture document (system structure), decision records (choices with rationale), learnings (captured experience), a task list (current work), a glossary (domain terminology), and an agent playbook (operating instructions). Each file has a single purpose, a defined lifecycle, and a distinct update frequency. Authoritative state is version-controlled alongside code and reviewed through the same mechanisms (diffs, pull requests, blame annotations).
Tier 2: Delivery Views: Derived representations of authoritative state, assembled for consumption by a model. A delivery view is produced by a deterministic assembly function that takes the authoritative state, a token budget, and an inclusion policy as inputs and produces a context window as output. The same authoritative state, budget, and policy must always produce the same delivery view. Delivery views are ephemeral (they exist only for the duration of a session), but their construction is reproducible.
Tier 3: Ephemeral State: Session transcripts, scratchpad notes, draft journal entries, and other artifacts that exist during or immediately after a session but are not authoritative. Ephemeral state is the raw material from which authoritative state may be extracted through human review, but it is never consumed directly by the assembly function.
This three-tier model resolves confusion present in earlier formulations: the claim that AI output is a deterministic function of the repository state. The corrected claim is that context selection is deterministic (the delivery view is a function of authoritative state), but model output remains stochastic, conditioned on the deterministic context. Formally:
delivery_view = assemble(authoritative_state, budget, policy)\noutput = model(delivery_view) # stochastic\n
The persistence layer's contribution is making assemble reproducible, not making model deterministic.

Separation enables progressive disclosure: the minimum context that matters for the current moment, with the option to load more when needed. A normal session loads the constitution, tasks, and conventions; a deep investigation loads decision history and journal entries from specific dates.
The budget mechanism is the constraint that makes separation valuable. Without a budget, the default behavior is to load everything, which destroys the attention density that makes loaded context useful. With a budget, the assembly function must prioritize ruthlessly: constitution first (always full), then tasks and conventions (budget-capped), then decisions and learnings (scored by recency). Entries that do not fit receive title-only summaries rather than being silently dropped (an application of the \"tell me what you don't know\" pattern identified independently by four systems in our landscape analysis).

The resulting set spans six categories: AI coding assistants (Continue, Sourcegraph/Cody, Aider, Claude Code), AI agent frameworks (CrewAI, AutoGen, LangGraph, LlamaIndex, Letta/MemGPT), autonomous coding agents (OpenHands, Sweep), session provenance tools (Entire), data versioning systems (Dolt, Pachyderm), pipeline/build systems (Dagger), and purpose-built knowledge stores (QubicDB, Kindex).

Our analysis of 17 systems reveals five categories of primitives, each making irrecoverable trade-offs:
Group A: Document/File Primitives: Human-readable documents as the primary unit. Documents are authored by humans, version-controlled in git, and consumed by AI tools. The invariant of this group is that the primitive is always human-readable and version-controllable with standard tools. Three systems participate in this pattern: the system described in this paper as a pure expression, and Continue (via its rules directory) and Claude Code (via CLAUDE.md files) as partial participants: both use document-based context as an input but organize around different core primitives.
Group B: Embedded Record Primitives: Vector-embedded records stored with numerical embeddings for similarity search, metadata for filtering, and scoring mechanisms for ranking. Five systems use this approach (LlamaIndex, CrewAI, Letta/MemGPT, QubicDB, Kindex). The invariant is that the primitive requires an embedding model or vector database for core operations: a dependency that precludes offline and air-gapped use.
Group C: State Snapshot Primitives: Point-in-time captures of the complete system state. The invariant is that any past state can be reconstructed at any historical point. Three systems use this approach (LangGraph, Entire, Dolt).
Group D: Event/Message Primitives: Sequential events or messages forming an append-only log with causal relationships. Four systems use this approach (OpenHands, AutoGen, Claude Code, Sweep). The invariant is temporal ordering and append-only semantics.
Group E: Construction/Derivation Primitives: Derived or constructed values that encode how they were produced. The invariant is that the primitive is a function of its inputs; re-executing the same inputs produces the same primitive. Three systems use this approach (Dagger, Pachyderm, Aider).

These convergent patterns carry extra validation weight because they emerged from different problem spaces:
Pattern 1: \"Tell me what you don't know\": When context is incomplete, explicitly communicate to the model what information is missing and what confidence level the provided context represents. Four systems independently converged on this pattern: inserting skip markers, tracking evidence gaps, annotating provenance, or naming output quality tiers.
Pattern 2: \"Freshness matters\": Information relevance decreases over time. Three systems independently chose exponential decay with different half-lives (30 days, 90 days, and LRU ordering). Static priority ordering with no time dimension leaves relevant recent knowledge at the same priority as stale entries. This pattern is in productive tension with the persistence model's emphasis on determinism: the claim is not that time-dependence is irrelevant, but that it belongs in the curation step (a human deciding to consolidate or archive stale entries) rather than in the assembly function (an algorithm silently down-ranking entries based on age).
Pattern 3: \"Content-address everything\": Compute a hash of content at creation time for deduplication, cache invalidation, integrity verification, and change detection. Five systems independently implement content hashing, each discovering it solves different problems 5.
Pattern 4: \"Structured beats freeform\": When capturing knowledge or session state, a structured schema with required fields produces more useful data than freeform text. Four systems evolved from freeform summaries to typed schemas: one moving from LLM-generated prose to a structured condenser with explicit fields for completed tasks, pending tasks, and files modified.
Pattern 5: \"Protocol convergence\": The Model Context Protocol (MCP) is emerging as a standard tool integration layer. Nine of 17 systems support it, spanning every category in the analysis. MCP's significance for the persistence model is that it provides a transport mechanism for context delivery without dictating how context is stored or assembled. This makes the approach compatible with both retrieval-centric and persistence-centric architectures.
Pattern 6: \"Human-in-the-loop for memory\": Critical memory decisions should involve human judgment. Fully automated memory management produces lower-quality persistent context than human-reviewed systems. Four systems independently converged on variants of this pattern: ceremony-based consolidation, interrupt/resume for human input, confirmation mode for high-risk actions, and separated \"think fast\" vs. \"think slow\" processing paths.
Pattern 6 directly validates the ceremony model described in this paper. The persistence layer requires human curation not because automation is impossible, but because the quality of persistent knowledge degrades when the curation step is removed. The improvement opportunity is to make curation easier, not to automate it away.

- A constitution with 13 inviolable rules across 4 categories (security, quality, process, context preservation)

The consolidation ratio (24 decisions compressed to 8 records, 75 learnings compressed to 18) illustrates the curation cost and its return: authoritative state becomes denser and more useful over time as related entries are merged, contradictions are resolved, and superseded decisions are marked.

Reversal 1: The two-tier persistence model: The original design included a middle storage tier for session copies. After 21 days of development, the middle tier was identified as a dead-end write sink (described in Section 6). The decision record captured the full context, and the removal was executed cleanly: 15 source files, a shell hook, and 45 documentation references. The pattern of a \"dead-end write sink\" was subsequently observed in 7 of 17 systems in our landscape analysis that store raw transcripts alongside structured context.
Reversal 2: The prompt-coach hook: An early design included a hook that analyzed user prompts and offered improvement suggestions. After deployment, the hook produced zero useful tips, its output channel was invisible to users, and it accumulated orphan temporary files. The hook was removed, and the decision record captured the failure mode for future reference.
Reversal 3: The soft-instruction compliance model: The original context injection strategy relied on soft instructions: directives asking the AI agent to read specific files. After measuring compliance across multiple sessions, we found a consistent 75-85% compliance ceiling. The revised strategy injects content directly, bypassing the agent's judgment about whether to comply. The learning record captures the ceiling measurement and the rationale for the architectural change.
Each reversal was captured as a structured decision record with context, rationale, and consequences. In a retrieval-based system, these reversals would exist only in chat history, discoverable only if the retrieval function happens to surface them. In the persistence model, they are permanent, indexable artifacts that inform future decisions.
","path":["The Thesis"],"tags":[]},{"location":"thesis/#73-compliance-ceiling","level":3,"title":"7.3 Compliance Ceiling","text":"The 75-85% compliance ceiling for soft instructions is the most operationally significant finding from the experience report. It means that any context management strategy relying on agent compliance with instructions (\"read this file,\" \"follow this convention,\" \"check this list\") has a hard ceiling on reliability.
The root cause is structural: the instruction \"don't apply judgment\" is itself evaluated by judgment. When an agent receives a directive to read a file, it first assesses whether the directive is relevant to the current task (and that assessment is the judgment the directive was trying to prevent).
The architectural response maps directly to the formal model defined in Section 3.1. Content requiring 100% compliance is included in authoritative_state and injected by the deterministic assemble function, bypassing the agent entirely. Content where 80% compliance is acceptable is delivered as instructions within the delivery view. The three-tier architecture makes this distinction explicit: authoritative state is injected; delivery views are assembled deterministically; ephemeral state is available but not pushed.

Early sessions (days 1-7) spent significant time re-establishing context: explaining conventions, re-stating constraints, re-deriving past decisions. Later sessions (days 25-33) began with the agent loading curated context and immediately operating within established constraints, because the constraints were in files rather than in chat history.
This compounding effect (where each session's context curation improves all subsequent sessions) is the primary return on the curation investment. The cost is borne once (writing a decision record, capturing a learning, updating the task list); the benefit is collected on every subsequent session load.
The effect is analogous to compound interest in financial systems: the knowledge base grows not linearly with effort but with increasing marginal returns as new knowledge interacts with existing context. A learning captured on day 5 prevents a mistake on day 12, which avoids a debugging session that would have consumed a day 12 session, freeing that session for productive work that generates new learnings. The growth is not literally exponential (it is bounded by project scope and subject to diminishing returns as the knowledge base matures), but within the observed 33-day window, the returns were consistently accelerating.

Whether the same crossover holds for larger teams, for codebases with different characteristics, or for teams adopting the model without having designed it remains an open empirical question.

Application Logic\nAI Interaction / Agents\nContext Retrieval Systems\nCognitive State Persistence Layer\nVersion Control / Storage\n
Current systems innovate primarily in the retrieval layer (improving how context is discovered, ranked, and delivered at query time). The persistence layer sits beneath retrieval and above version control. Its role is to maintain the authoritative state that retrieval systems may query but do not own. The relationship is complementary: retrieval answers \"What in the corpus might be relevant?\"; cognitive state answers \"What must be true for this system to operate correctly?\" A mature system uses both: retrieval for discovery, persistence for authority.

Reproducibility is a requirement: If a system must be able to answer \"Why did this output occur, and can it be produced again?\" then deterministic, version-controlled context becomes necessary. This is relevant in regulated environments, safety-critical systems, long-lived infrastructure, and security-sensitive deployments.
Knowledge must outlive sessions and individuals: Projects with multi-year lifetimes accumulate architectural decisions, domain interpretations, and operational policy. If this knowledge is stored only in chat history, issue trackers, and institutional memory, it decays. The persistence model converts implicit knowledge into branchable, reviewable artifacts.
Teams require shared cognitive authority: In collaborative environments, correctness depends on a stable answer to \"What does the system believe to be true?\" When this answer is derived from retrieval heuristics, authority shifts to ranking algorithms. When it is versioned and human-readable, authority remains with the team.
Offline or air-gapped operation is required: Infrastructure-dependent memory systems cannot operate in classified environments, isolated networks, or disaster-recovery scenarios.

Heuristic retrieval is sufficient when correctness is non-critical, outputs are disposable, and historical reconstruction is unnecessary.
Maximum automatic recall from large corpora: Vector retrieval systems provide superior performance when the primary task is searching vast, weakly structured information spaces. The persistence model assumes that what matters can be decided and that this decision is valuable to record.

Step 2: Make inclusion deterministic: Define explicit assembly rules. Retrieval may still exist, but it is no longer authoritative.
Step 3: Move policy into cognitive state: When system behavior depends on stable constraints, encode those constraints as versioned knowledge. Behavior becomes reproducible.
Step 4: Optimize assembly, not retrieval: Once the authoritative layer exists, performance improvements come from budgeting, caching, and structural refinement rather than from improving ranking heuristics.
","path":["The Thesis"],"tags":[]},{"location":"thesis/#94-the-curation-cost","level":3,"title":"9.4 The Curation Cost","text":"The primary objection to this model is the cost of explicit knowledge curation. This cost is real. Writing a structured decision record takes longer than letting a chatbot auto-summarize a conversation. Maintaining a glossary requires discipline. Consolidating 75 learnings into 18 records requires judgment.
The response is not that the cost is negligible but that it is amortized. A decision record written once is loaded hundreds of times. A learning captured today prevents repeated mistakes across all future sessions. The curation cost is paid once; the benefit compounds.
The experience report provides rough order-of-magnitude numbers. Across 389 sessions over 33 days, curation activities (writing decision records, capturing learnings, updating the task list, consolidating entries) averaged approximately 3-5 minutes per session. In early sessions (days 1-7), before curated context existed, re-establishing context consumed approximately 10-15 minutes per session: re-explaining conventions, re-stating architectural constraints, re-deriving decisions that had been made but not persisted. By the final week (days 25-33), the re-explanation overhead had dropped to near zero: the agent loaded curated context and began productive work immediately.
At ~12 sessions per day, the curation cost was roughly 35-60 minutes daily. The re-explanation cost in the first week was roughly 120-180 minutes daily. By the third week, that cost had fallen to under 15 minutes daily while the curation cost remained stable. The crossover (where cumulative curation cost was exceeded by cumulative time saved) occurred around day 10. These figures are approximate and derived from a single project with a small team already familiar with the model; the crossover point will vary with project complexity, team size, and curation discipline.

Section-level deterministic budgeting: Current assembly operates at file granularity. Section-level budgeting would allow finer-grained control (including specific decision records while excluding others within the same file) without sacrificing determinism.
Causal links between decisions: The experience report shows that decisions frequently reference earlier decisions (superseding, extending, or qualifying them). Formal causal links would enable traversal of the decision graph and automatic detection of orphaned or contradictory constraints.
Content-addressed context caches: Five systems in our landscape analysis independently discovered that content hashing provides cache invalidation, integrity verification, and change detection. Applying content addressing to the assembly output would enable efficient cache reuse when the authoritative state has not changed.
Conditional context inclusion: Five systems independently suggest that context entries could carry activation conditions (file patterns, task keywords, or explicit triggers) that control whether they are included in a given assembly. This would reduce the per-session budget cost of large knowledge bases without sacrificing determinism.
Provenance metadata: Linking context entries to the sessions, decisions, or learnings that motivated them would strengthen the audit trail. Optional provenance fields on Markdown entries (session identifier, cause reference, motivation) would be lightweight and compatible with the existing file-based model.
","path":["The Thesis"],"tags":[]},{"location":"thesis/#11-conclusion","level":2,"title":"11. Conclusion","text":"AI-assisted development has treated context as a \"query result\" assembled at the moment of interaction, discarded at the session end. This paper identifies a complementary layer: the persistence of authoritative cognitive state as deterministic, version-controlled artifacts.
The contribution is grounded in three sources of evidence. A landscape analysis of 17 systems reveals five categories of primitives and shows that no existing system provides the combination of human-readability, determinism, zero dependencies, and offline capability that the persistence layer requires. Six design invariants, validated by 56 independent rejection decisions, define the constraints of the design space. An experience report over 389 sessions and 33 days demonstrates compounding returns: later sessions start faster, decisions are not re-derived, and architectural reversals are captured with full context.
The core claim is this: persistent cognitive state enables causal reasoning across time. A system built on this model can explain not only what is true, but why it became true and when it changed.
When context is the state:
- Reasoning is reproducible: the same authoritative state, budget, and policy produce the same delivery view.
- Knowledge is auditable: decisions are traceable to explicit artifacts with context, rationale, and consequences.
- Understanding compounds: each session's curation improves all subsequent sessions.
The choice between retrieval-centric workflows and a persistence layer is not a matter of capability but of time horizon. Retrieval optimizes for relevance at the moment of interaction. Persistence optimizes for the durability of understanding across the lifetime of a project.

This appendix provides a representative sample (two per invariant) to illustrate the methodology.
Invariant 1: Markdown-on-Filesystem (11 rejections): CrewAI's vector embedding storage was rejected because embeddings are not human-readable, not git-diff-friendly, and require external services. Kindex's knowledge graph as core primitive was rejected because it requires specialized commands to inspect content that could be a text file (kin show <id> vs. cat DECISIONS.md).
Invariant 2: Zero Runtime Dependencies (13 rejections): Letta/MemGPT's PostgreSQL-backed architecture was rejected because it conflicts with local-first, no-database, single-binary operation. Pachyderm's Kubernetes-based distributed architecture was rejected as the antithesis of a single-binary design for a tool that manages text files.
Invariant 3: Deterministic Assembly (6 rejections): LlamaIndex's embedding-based retrieval as the primary selection mechanism was rejected because it destroys determinism, requires an embedding model, and removes human judgment from the selection process. QubicDB's wall-clock-dependent scoring was rejected because it directly conflicts with the \"same inputs produce same output\" property.
Invariant 4: Human Authority (6 rejections): Letta/MemGPT's agent self-modification of memory was rejected as fundamentally opposed to human-curated persistence. Claude Code's unstructured auto-memory (where the agent writes freeform notes) was rejected because structured files with defined schemas produce higher-quality persistent context than unconstrained agent output.
Invariant 5: Local-First / Air-Gap Capable (7 rejections): Sweep's cloud-dependent architecture was rejected as fundamentally incompatible with the local-first, offline-capable model. LangGraph's managed cloud deployment was rejected because cloud dependencies for core functionality violate air-gap capability.
Invariant 6: No Default Telemetry (4 rejections): Continue's telemetry-by-default (PostHog) was rejected because it contradicts the local-first, privacy-respecting trust model. CrewAI's global telemetry on import (Scarf tracking pixel) was rejected because it violates user trust and breaks air-gap capability.
The remaining 9 rejections did not map to a specific invariant but were rejected on other architectural grounds: for example, Aider's full-file-content-in-context approach (which defeats token budgeting), AutoGen's multi-agent orchestration as core primitive (scope creep), and Claude Code's 30-day transcript retention limit (institutional knowledge should have no automatic expiration).

Subject: [PATCH 4/5] docs(typography): brand-backtick sweep across docs/
CONSTITUTION mandates "No Broken Windows" / "Completion Over
Motion": fix obvious issues when encountered, no half measures.
The brand convention `ctx` (monotype backtick wherever
possible, frontmatter titles being the documented exception)
had drifted across the entire docs tree. A programmatic sweep
caught 236 bare `ctx` tokens across 81 source files and
wrapped each one in backticks, preserving content already
inside backtick spans and code fences.
The sweep respects:
- Triple-backtick fenced code blocks, including indented
fences inside MkDocs `!!!` admonitions (caught a regression
on first pass where indented JSON inside admonitions was
corrupted; FENCE regex now matches `^\s*` + triple-backtick
to handle both root-level and indented fences).
- Existing inline-code spans on the same line (parser tracks
backtick pairs and never wraps `ctx` inside an already-
protected range).
- Frontmatter reserved keys (title, name, description, icon)
and image alt-text (![ctx]) -- per the documented exception
for frontmatter titles, which avoid backticks entirely.
- Link-reference definitions: `[name]: url "title"` lines.
- The copyright-header comment block at the top of every
file: `# / ctx:`.
- Package identifiers via `@`: `ctx@activememory-ctx` left
intact (added `@` to the word-exclusion set after seeing
this pattern in install snippets).
Known false-positives that the detector flags but the
transform correctly left alone: 13 multi-line inline-code
spans (the open backtick is on one line, the close on the
next). CommonMark permits this; the transform's line-at-a-
time logic detects the unclosed-on-this-line state and treats
the rest of the line as protected, which is the right
behavior. The detector is line-scoped, so it can't see across
line boundaries and registers false positives.
Two outright corruptions surfaced during validation and were
fixed manually:
- docs/home/context-files.md:532 -- a multi-line code span
the transform misjudged in its second-line content, leaving
``ctx` steering preview` (double-backtick + orphan close).
Reverted to the original `ctx steering preview`.
- docs/reference/comparison.md:218 -- same pattern: the
transform produced ``ctx` serve` from a multi-line span;
reverted to `ctx serve`.
One YAML frontmatter breakage on docs/blog/2026-02-03-the-
attention-budget.md: the sweep wrapped `ctx` inside a
`topics:` list-item, producing `- `ctx` primitives` which is
invalid YAML (a value starting with backtick is not a valid
unquoted scalar). The fix follows the documented frontmatter
exception -- drop backticks in YAML metadata, since the bare
word is fine in that surface (YAML topics are tags-like
metadata, not rendered prose).
site/ regenerated via `make site`. The sweep touched 81
source files; the regen produced corresponding changes in the
published site output (every page's nav also rebuilds when
the source set changes, hence the larger total file count).
