fix(activation): gate dispatch not reads, receipt via preflight, identity-only delivery - #894

Conversation
Adds bench/activation-ordering.sh, which asks a harness to echo the workflow-activation nonce from its UserPromptSubmit context as its first tool call, then compares that call against the receipt file. Confirms ORDER=context-before-first-call on Codex; the Claude leg is blocked in this sandbox (see task-0-report.md) and needs an operator decision. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…ordering Replaces the blocked --dangerously-skip-permissions invocation with a precise --allowedTools='Bash(printf:*)' allow list per the operator's standing rule. Also adds the same PreToolUse-blocked-command stderr fallback the Codex leg already has, and fixes --allowedTools' variadic arg parsing swallowing the prompt positional (needs `=`, not a space). Result: ORDER=no-delivery -- no UserPromptSubmit hook fired at all for this claude -p invocation, so there was no receipt/nonce to relay. Not a script defect; recorded as a real finding in the README for Task 4 to re-check after the activation-gate change. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…he Claude probe The prior no-delivery result traced to the user's installed agentkit@agent-kit plugin being disabled at 0.8.1 on this machine, not to UserPromptSubmit failing to fire in claude -p. Add --plugin-dir (required for --harness claude, ignored for codex) to load the built plugin tree (plugin/agentkit, from tests/build-plugin.sh) for the probe session only, so the probe measures this branch's hooks and never touches the user's installed plugins. Result: ORDER=context-before-first-call on Claude too. The receipt's skillsRoot points at plugin/agentkit/skills and its nonce matches the model's sole tool call byte-for-byte. Both harnesses now agree. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
A root paid two denied reads, an ack and two checks before its first real call. Reads, edits and inspection now proceed while delivery is pending; only spawn, worktree creation, push and PR creation wait for the receipt. The active-branch inspection() bypass is kept (not deleted, as the brief's draft rewrite proposed) because a stale, content-mismatched active record still needs to permit bounded diagnostic reads before validate() raises ContentMismatch; tests/probe/test-activation.py's test_stale_diagnostic_reads_and_searches_are_bounded pins this. Its other two activation-boundary tests are updated for the new pending contract: dispatch-class calls are gated, but an arbitrary non-dispatch Bash command (even one shaped like a mutation, or decorated with a shell expansion) now proceeds while pending, same as any other read. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
dispatch_class used re.search(pattern, command, re.MULTILINE), so
"^\s*git\s+push" matched any LINE starting with "git push" -- including
heredoc bodies and quoted data (a commit message, a README snippet, a
"cat <<EOF" with example CLI text). While pending that produced a false
deny on inert text, the exact "few turns" cost this task exists to remove,
and the kit's known data-vs-executed false-positive class.
Add executed_text() to strip heredoc bodies and quoted strings before
matching, drop re.MULTILINE, and anchor the git/gh patterns at a segment
start ("^" or after ;/&/|/() rather than the string start, so "cd repo &&
git push" is still caught while "printf 'git push'" is not.

executed_text() plus the (?:^|[;&|(]\s*) anchor missed two shell statements separated only by a newline, e.g. "cd repo\ngit push origin main", which bash executes as a real push -- a false allow while pending. Because heredoc bodies and quoted strings are already stripped before matching, a newline is now a safe segment boundary. Add \n to the anchor character class in both the git and gh patterns. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The receipt used to cost its own tool call. Preflight is the first command every workflow runs, so it now carries --activation-nonce and promotes the record before it writes the contract; a wrong nonce fails before any state. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The native skill injection already delivers the full body; the hook's copy was truncated and spilled to disk on both harnesses. Delivery is now the preflight line plus identity, under the context caps of either harness. The probe suite's stale-leaf and upgrade-resume tests asserted on the now-removed embedded body text; they now assert on deliveredDigest matching the current on-disk bytes instead. The advertised-invocation and explicit-selector tests asserted on a literal "--skill" flag that only appeared inside the removed body copy; the actual preflight command uses --workflow, so the assertions now match it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
v0.9.13 is tagged and shipped bytes changed under it on this branch, so tests/check-release-version.sh fails. Move source and generated manifests to the next unpublished patch (prepare-next-version.sh cannot run from a linked worktree, so this applies its bump-version.sh + build-plugin.sh steps by hand). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Claude Code confirms ORDER=context-before-first-call with 0 denied calls against the rebuilt plugin tree, down from 2 pre-change. The Codex leg could not be exercised non-interactively: a per-repo .codex/hooks.json pointed at this branch's hooks is untrusted and silently skipped in favor of the already-trusted installed 0.9.13 cache, so its 1 denied call reflects the old hooks, not this change.

Final-review fixes for fix/activation-option-b: - Important #1: executed_text() unwraps single-token quoted strings before stripping multi-token ones, so the kit's own documented quoted absolute helper-path invocation is matched instead of treated as inert data. - Important #2: git/gh DISPATCH_COMMANDS patterns use a non-path-boundary lookbehind with optional -c/-C groups instead of a shell-operator anchor, catching git -C, leading whitespace, and loop/conditional bodies that the anchor missed once heredocs and quotes are already stripped. - Minor #1: helper-name patterns anchor to command position so a read of a helper file (sed/rg) is no longer denied while pending. - Minor #2: agent-preflight.sh dies (exit 2) naming the missing flag when --activation-nonce is given without --activation-session/--workflow, instead of reaching ack with empty required flags. - Minor #3: <<- heredocs with a tab-indented terminator strip correctly. - Minor #5: Step 0's "separately takes" sentence no longer invites a redundant second preflight call, in all four SKILL.md files; all four end up smaller. - Minor #7: deliver() reuses record["version"] instead of a second identity(args) call.

…requires re-reading the skill Two P2s from a blind adversarial review of PR #894: 1. executed_text() stripped quoted strings as inert data before matching DISPATCH_COMMANDS, so `bash -c 'git push origin HEAD'` was allowed while pending — the kit's own recipes route real commands through `bash -c '...'` on the zsh harness shell. Unwrap `(bash|sh|zsh|dash) -c '...'` bodies into executed text before the generic quote strip runs. 2. deliver(..., recovery=True) told a worker to run the receipt command without ever requiring it to re-read the changed SKILL.md body (neither harness delivers the full body through hook context). The recovery lead now makes reading SKILL.md in full an explicit, ordered prerequisite of the receipt command. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

`git push` and `gh pr create` counted as dispatch wherever a space preceded them, so `echo git push origin main` cost a denied turn while a receipt was pending. The matcher now requires command position: the start of the text, a shell operator, or a known wrapper (env, VAR=x, timeout, nohup, sudo, xargs, exec, do/then). Absolute git paths are covered by the same rule. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Inline comments:
In `@agentkit/skills/.shared/scripts/lib/workflow-activation.py`:
- Around line 340-346: Update the shell-command unwrapping logic around
`shell_c` and `unwrapped` to recognize shell options that bundle `-c` with other
flags, such as `-lc`, and expose the executed body for classification before the
quote-removal pass. If the body cannot be reliably classified, deny the call
rather than stripping it and allowing execution.
- Around line 334-335: Update the heredoc-stripping logic in dispatch_class so
it removes only the heredoc body and delimiter, preserving executable commands
on the header line for classification.
- Line 323: Update the Git dispatch matching around COMMAND_POSITION to inspect
parsed arguments that preserve quoted paths instead of matching the
whitespace-normalized executed_text, so a quoted path passed to git -C cannot be
mistaken for the push subcommand.
- Around line 253-258: Update the context assembled in the workflow activation
code to include the exact skill path and require reading its full contents after
preflight but before work when native skill content is absent. Keep the existing
preflight command and installed identity output unchanged.
In `@bench/activation-ordering.sh`:
- Line 48: Update the first-command extraction in the `first_call` assignment to
select the first matching Bash tool-use value in `jq` before converting it to
text, so multiline commands remain intact. Apply the same change to the
extraction on line 32.
- Line 32: Update the first-tool-attempt checks in the activation-ordering
script, including the `first_call` selection and the corresponding check at line
48, to inspect the earliest tool attempt across all tool types, including
blocked attempts. Do not filter to completed Bash command executions; validate
the nonce against that earliest attempt before accepting the ordering.

…gaps CodeRabbit's review of PR #894 found four ways a pending receipt could still be bypassed or a real command mis-read, and two probe selectors that could pick the wrong call. Heredoc stripping now keeps the header line's own commands; shell -c bodies are unwrapped for bundled flags such as -lc; multi-token quoted strings become a placeholder token so `git -C '<path with spaces>' push` keeps its subcommand; a workflow selected from the operator's words (no native skill injection) is told the exact skill path and to read it in full before dispatch. The ordering probe now takes the earliest tool attempt of any kind as one JSON value, so blocked attempts and multi-line commands are seen. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Why
A parallel-issues root paid six tool calls of activation ceremony before its first real call on 2026-09-23: two denied reads, an ack, two checks, one preflight. The hook also shipped the 66 KB skill body as context that both harnesses truncated and spilled to disk while the native skill injection delivered it in full. The receipt is still the only proof against the #722 class (six hours, 261.8M tokens with no plugin loaded), so it stays; the ceremony goes.
What
agent-preflight.sh --activation-noncepromotes the receipt inside the first call every workflow already makes; a wrong nonce fails before any state is written.bench/activation-ordering.shproves on both harnesses that hook context arrives before the model's first tool call.Testing
