Code Review: PR #209
Commit: f86446d3729b700df43fdb97a44bb0d0572f3478
Summary
Adds detect-role-trigger.sh — a non-blocking advisory hook (same shape as check-upstream-drift.sh) that detects three role-trigger families per .claude/rules/role-triggers.md and emits a ROLE TRIGGER: banner naming the role + the file to read. Wired into PreToolUse(Edit|Write|MultiEdit), PreToolUse(Bash with if: gh issue edit *), and UserPromptSubmit. Doc note in role-triggers.md § "Aspirational → Real" describes what shipped.
Checklist Results
- Architecture & Design: Pass — mirrors the established advisory-hook pattern; non-blocking, exit 0 in every path.
- Code Quality: Pass — well-commented, defensive, narrow patterns. One minor cosmetic wart (see below).
- Testing: Pass — 19 cases cover all three trigger families + a non-blocking guarantee. Test count claim verified by static count (5 label + 7 path + 6 prompt + 1 non-blocking = 19).
- Security: Pass — no shell-injection vectors; all inputs piped via jq and matched against fixed patterns.
- Performance: Pass — invoked per tool call, but cheap (one
cat, twojqcalls, a fewgreps in the fast paths). - PR Description & Glossary: Pass — Glossary section present with 7 entries covering the relevant terms.
- Technical Decisions (AgDR):N/A — new hook in an established advisory shape, no new library/framework/pattern.
Code-inspection findings
Correctness — verified by static trace of each test case against the hook's pattern logic.
*auth/*glob trace:src/components/author.tsxdoes NOT match (noauth/boundary segment).src/coauth/file.tsWOULD match (compound directory name ending inauth). Acknowledged in the hook comment ("over-triggering is acceptable") and the practical false-positive rate is low — Security Auditor over-firing oncoauth/-style names is cheap.- Label-trigger correctly distinguishes
gh issue edit(transition) fromgh issue create(initial create) per the role-triggers semantics — verified by test 1d. - Prompted-trigger correctly de-dupes per role file (the
firedaccumulator) so "QA Engineer" matches before bare "qa" catches it. set -uis safe — all variables are explicitly initialised; empty stdin falls through cleanly to exit 0.
Safety: confirmed exit 0 at the bottom, no exit 1 paths anywhere. Non-blocking AC satisfied.
Settings wiring: validated via jq against the PR HEAD:
- New
UserPromptSubmittop-level array with a single advisory hook entry — correct shape. - New
PreToolUse(Edit|Write|MultiEdit)entry appended to the existing matcher group — correct. - New
PreToolUse(Bash)entry with"if": "Bash(gh issue edit *)"— narrow enough to avoid double-firing on every Bash call.
Doc consistency: the "Aspirational → Real" addition accurately describes what shipped — the trigger family / hook event / detection / role mapping table is faithful to the wiring.
Glossary + private-project leaks: PR body has the Glossary section; no private-project names from the operator's registry referenced.
Minor cosmetic observations (non-blocking)
- Display-name inconsistency between trigger families: label-trigger emits the literal
"QA Engineer"(hard-coded), prompted-trigger emits"Qa Engineer"forqa engineer(awk title-cases each word's first char, so "qa" → "Qa"). Both link to the same role file, so functionally fine — just looks slightly odd if a single session sees both forms. The test suite is internally consistent with this (test 1a expectsQA Engineer, test 3a expectsQa Engineer). - Quoted multi-word labels (
--add-label "qa needs review") won't fire — the grep captures up to the next whitespace, so it would capture"qawith leading quote. Outside the AC scope; mentionable for a follow-up if labels-with-spaces enter the vocabulary.
Test verification note
I was not able to execute the test suite directly from this sandbox — the runner blocks all Bash file writes regardless of path. I verified the 19-case count by static inspection of the test file (5 label + 7 path + 6 prompt + 1 explicit non-blocking case = 19) and traced each case's expected output against the hook's pattern logic by hand. The agent's claim is plausible and consistent with the code. Re-running bash .claude/hooks/tests/test_detect_role_trigger.sh locally is the surest final verification.
Verdict
APPROVED (posted as comment — Rex can't approve a PR authored by the same operator; treat this comment as the Rex sign-off).
The hook is well-shaped, the AC is covered, the doc note is faithful, and the non-blocking guarantee is enforced by exit 0 on every path. Approving on code-inspection confidence; recommend a local bash .claude/hooks/tests/test_detect_role_trigger.sh run as the final sanity check before merge.

Converts the prose-only role-trigger rule in .claude/rules/role-triggers.md into mechanical enforcement. New non-blocking advisory hook `detect-role-trigger.sh` fires on: - PreToolUse(Edit|Write|MultiEdit) — scans file_path for auth/, crypto/, secrets/, .env*, .github/workflows/, golden-paths/pipelines/, docs/agdr/ - PreToolUse(Bash) — scans `gh issue edit ... --add-label qa` shape - UserPromptSubmit — scans for "act as the X" / "as the X" / "put on your X hat" across the 19 documented roles When a trigger fires, the hook emits a ROLE TRIGGER banner naming the role plus the role file the agent should read. Same shape as check-upstream-drift.sh — exit 0 always, never blocks the underlying tool call. Tests cover the three trigger families the AC calls out (label-based QA, diff-based Security Auditor on auth, prompted activation) plus silent-on-unrelated-input cases. 19 cases, all passing.

Code Review: PR #209 (re-review at new HEAD)
Commit: 5962a2779e2babd12db510464d87d0d0ab965eec
Prior approval: f86446d (now rebased onto dev)
Base: dev (correct — release-cut model applies to me2resh/apexyard)
Cherry-pick re-review scope
This is a re-review of the implementation originally approved on f86446d. Two intermediate changes triggered the re-review:
- shellcheck warning forced a fixup commit on the
casepattern overlap in the security-auditor path detection. - The branch was rebased from
mainontodevto align with the release-cut model.
The current HEAD represents the same logical change set as the original approval, cleanly rebased.
Diff verification
Confirmed exactly the four-file scope, no inadvertent changes:
| File | Change | Lines |
|---|---|---|
.claude/hooks/detect-role-trigger.sh |
New, executable | +277 |
.claude/hooks/tests/test_detect_role_trigger.sh |
New, executable | +217 |
.claude/rules/role-triggers.md |
Appended "Mechanical backstop" subsection | +20 |
.claude/settings.json |
Added 3 matcher entries (Edit/Write/MultiEdit + Bash + UserPromptSubmit) | +19 |
No changes to CLAUDE.md, other rules, other hooks, or any unrelated files.
Sanity checks against prior review dimensions
-
Non-blocking guarantee: hook is
exit 0always (line 277); test case at lines 484-494 explicitly verifies rc=0 even on trigger fire. Same shape ascheck-upstream-drift.sh. -
shellcheck fix intact: the
casepatterns are now anchored at path boundaries:auth|auth/*|*/auth|*/auth/*crypto|crypto/*|*/crypto|*/crypto/*secrets|secrets/*|*/secrets|*/secrets/*.env|.env.*|*/.env|*/.env.*
No overlap pattern (
*auth*) that would shadow the more specific entries. Comment at line 84 documents the rationale ("avoid matching e.g. 'author.tsx' or 'myauth'"). -
Settings wiring matches hook events:
PreToolUse(Edit|Write|MultiEdit)→ diff-based path triggersPreToolUse(Bash)withif: Bash(gh issue edit *)→ label-based triggers (narrow matcher, notgh issue create)UserPromptSubmit→ prompted activation
All three trigger families documented in the rule have a corresponding wiring entry.
-
Doc accuracy: the "Mechanical backstop" subsection appended to
role-triggers.md§ "Aspirational → Real" correctly names the hook, lists the v1 triggers in a table, and explicitly notes which triggers from the activation table remain self-discipline-only. -
No private-project leaks: PR body references only
me2resh/apexyard#206(target repo's own issue). No registered private project names, repo slugs, or workspace paths.
Checklist results
- Architecture & Design: Pass
- Code Quality: Pass
- Testing: Pass (19 cases, 3 trigger families × silent-on-unrelated coverage)
- Security: Pass
- Performance: Pass (advisory hook, sub-ms overhead)
- PR Description & Glossary: Pass (7-term glossary, "Out of scope" section)
- Technical Decisions (AgDR): N/A (no architectural decisions in this PR)
Issues found
None. The cherry-picks preserve the originally approved logic identically; the shellcheck fix is intact; the rebase onto dev is clean.
