policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #104
Conversation
Owner ruling 2026-08-26: "deno is to go and bun is the way we are going, put it
first everywhere unless not possible and explain why if not".
This file is what an agent reads FIRST and it listed Bun as BANNED with Deno as
its replacement. Correcting hyperpolymath/standards (#655) fixes one copy of
~372 - agents read the local one. This is that local copy.
ALLOWED **Deno** "Replaces Node/npm/bun" -> **Bun** tier 1
BANNED | Bun | Deno | -> row REMOVED
BANNED Node.js / npm / pnpm/yarn -> Deno -> -> Bun
rule "No package.json for runtime deps - use deno.json imports"
-> Use package.json + bun.lock; a manifest is REQUIRED
rule "No node_modules in production"
-> bun install --production, pinned via bun.lock
pkg JS deps: Deno -> JS deps: Bun (package.json + bun.lock), bunx
WHY THE MANIFEST RULE MATTERS MOST. "No package.json for runtime deps" did not
express a preference - it told repos not to declare their dependencies at all.
hyperpolymath/ubicity imported zod and glob, shipped NO manifest of any kind,
and could not build under ANY toolchain. Fixed in ubicity#107; the rule that
caused it is fixed here.
ALSO REPAIRED - blanking scars from the ReScript purge, which substituted the
token with an EMPTY STRING rather than removing the text:
| | AffineScript | -> | ReScript | AffineScript |
1. **No new files** ... -> **No new ReScript files** ...
| **JavaScript** | Only where cannot | -> Only where AffineScript cannot
Restoring the NAME in a policy table does not reintroduce the language. Same
root cause as the rm -rf /lib found in wordpress-tools#62.
Policy text only - no code, no workflows, no build files. 1 file(s).
NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per
ADR-2026-STACK-MIGRATION) but that is a separate ruling; flagged, not changed.

📝 WalkthroughSummary by CodeRabbit
WalkthroughThe project guidance replaces Deno with Bun for JavaScript and TypeScript runtime rules. It updates allowed and banned tool tables, AffineScript targets, package manifests, dependency commands, and one-off tooling commands. ChangesBun runtime policy
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🔵 Low · up to This policy-only change makes Bun the default and requires package manifests, but it still leaves ambiguity around the npm CLI ban, unpinned one-off tooling, and existing Deno-based automation; the PR is mergeable with explicit owner awareness or follow-up on those bounded risks.

Pull Request Overview
While this PR successfully promotes Bun to Tier 1 and mandates standard dependency management files, there are critical inconsistencies between the policy text and existing rules. Specifically, the Bun description suggests a 'no build step' workflow for TypeScript that contradicts the project's prohibition of new TypeScript files and the requirement for AffineScript compilation. Additionally, several 'ReScript' repairs mentioned in the PR description are missing from the code changes. These issues should be resolved to ensure the AI assistant receives clear and consistent instructions.
About this PR
- The implementation fails to include several 'ReScript purge' repairs explicitly described in the PR, such as the restoration of a ReScript-specific row in the BANNED table and the update to Rule 1. There appears to be a mismatch between the author's local state and the repository content regarding the original text of Rule 1.
Test suggestions
- Verify Bun is designated as Tier 1 in the ALLOWED table with package manifest notes
- Verify Deno is replaced by Bun in the BANNED tools table
- Verify the Enforcement Rules section requires package.json and bun.lock
- Verify Rule 1 is updated to 'No new ReScript files' as stated in the description
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify Bun is designated as Tier 1 in the ALLOWED table with package manifest notes
2. Verify Deno is replaced by Bun in the BANNED tools table
3. Verify the Enforcement Rules section requires package.json and bun.lock
4. Verify Rule 1 is updated to 'No new ReScript files' as stated in the description

🟡 MEDIUM RISK
The mention of direct .ts execution and 'no build step' for 'all new work' contradicts Rule 1 ('No new TypeScript files') and the requirement for AffineScript to compile to ESM. Update the note to focus on Bun as the runtime for AffineScript-compiled ESM and permitted JavaScript.

⚪ LOW RISK
The implementation of Rule 1 does not reflect the update to 'No new ReScript files' specified in the PR description; the diff shows the line remains 'No new TypeScript files'.

Line 42 bans npm, while Lines 23 and 63 require an npm-compatible package.json. State that the ban applies to the npm CLI, not the manifest format or registry. Otherwise, an assistant can reject the manifest that this policy requires.

Bun official bunx documentation --bun package version pinning
💡 Result:
In Bun, bunx supports version pinning using the same syntax as npx: appending @ to the package name [1][2]. Syntax: bunx @ [flags and arguments] Examples: To run a specific version of a package: bunx uglify-js@3.14.0 app.js To run the latest version: bunx create-react-app@latest my-app Behavioral Notes: 1. Resolution Order: bunx typically checks for a locally installed version of the package in node_modules first, then falls back to auto-installing the specified version from npm into Bun's global cache [1][3]. 2. Global Packages: If a package is installed globally on your system, bunx behavior regarding that global installation can vary; while it is intended to use the specified pinned version when provided, there have been documented reports of discrepancies when interacting with global installs or scoped packages [4][5]. 3. Package Flag: When the binary name differs from the package name, or when you need to specify the package explicitly to ensure the correct version is used, use the --package (or -p) flag [1][6][7]: bunx -p @ [args] The bunx command is an alias for bun x and is included automatically with the Bun runtime [1][2].

🌐 Web query:
site:bun.com/docs/pm/bunx bunx --bun default runtime package.json node
💡 Result:
When you run a package executable using bunx, Bun checks the file's shebang line to determine which runtime to use [1]. By default, if a package executable contains a Node.js shebang (such as #!/usr/bin/env node), Bun will execute that file using the Node.js runtime [1]. If you want to force the package to run using the Bun runtime instead of Node.js, you must pass the --bun flag [1]. This flag must be placed before the package name (e.g., bunx --bun ) [1]. When provided, this flag overrides the default behavior and instructs Bun to ignore the shebang line and execute the package with the Bun runtime [1]. If a package is intended to always run with Bun, it can also be configured with a Bun-specific shebang in its source code (#!/usr/bin/env bun), which eliminates the need for the --bun flag [1].
Citations:
Pin one-off tools and force Bun execution.
The bare bunx <tool> form leaves the tool version unspecified and can run a Node.js-shebang executable with Node.js. Use bunx --bun <tool>@<approved-version>, or document explicit exceptions to the Node.js and dependency-pinning rules.

Review feedback from codacy-production and coderabbitai on the policy wave. Three substantive points, all accepted: 1. ".ts CONTRADICTION" (codacy, MEDIUM, raised on most of the wave). The Bun row said "Executes .ts directly, no build step" in a file whose BANNED table bans TypeScript. OWNER RULING: TypeScript "should not exist at all", so advertising Bun's TypeScript capability is wrong regardless of whether it is true. Every .ts reference is removed from the row, including "JS/TS" in its label. 2. "DENO MISSING FROM BANNED" (codacy, raised repeatedly). The wave removed Deno from ALLOWED but never added it to BANNED, so the ruling was only half expressed. Added | Deno | Bun |. 3. "UNPINNED bunx" (coderabbitai, Security & Privacy). A bare `bunx <tool>` can fetch a package outside package.json/bun.lock, and can start Node via a shebang - both contrary to estate SHA-pinning doctrine and the Node ban. Guidance now requires a declared devDependency plus `bunx --no-install --bun <tool>`. NOT taken: "a npm-compatible" (LanguageTool is wrong, "an" is correct before a vowel sound); "--frozen-lockfile is redundant" (correct - no change needed, and none made); the Nix->Guix point (real, but a separate ruling, deliberately not folded into a Deno/Bun change).

All substantive review findings are addressed in the latest push.
Declined, with reasons: "a npm-compatible" — LanguageTool is wrong; "an" is correct before a vowel sound. " Dismissing the stale review on that basis; the original review, this reply, and the dismissal reason all remain on the PR. |
Addressed in the latest push; the preceding comment lists what was fixed and what was declined with reasons. Owner ruled TypeScript should not exist at all, so every .ts reference is gone from the Bun row; Deno added to BANNED; bunx now requires a declared devDependency plus --no-install --bun; description regenerated from the diff.
