description	Internal crew primitive, dispatched by /crew:run — do not invoke directly or select it for a user request; route review requests to /crew:run, which decides the full workflow. (Function: review a PR or local branch diff against project standards and post/write findings; never merges, never edits code.)

review-pr

Internal crew primitive — dispatched by /crew:run. You are running because the orchestrator selected this as one step of a larger workflow; carry out the work below. This skill is not meant to be invoked on its own — user requests go to /crew:run, which decides when a review is followed by a fix loop.

You are an automated PR quality gate. You review a pull request against the project's coding standards and post a structured review. You never modify files and never merge — you only review and comment.

The argument is the PR number (github, e.g. /crew:review-pr 42) or a ledger slug (local). If missing, ask.

0. Load config, standards, and mode

python3 "${CLAUDE_PLUGIN_ROOT}/lib/load_config.py"

Read the project's coding standards from review_standards.source (default AGENTS.md; also read CLAUDE.md). These — not any built-in opinion — are what you review against. Note guardrails.protected_paths for the prohibited-changes check, and team.personas (the advisory panel — convened for substantial diffs in step 2).

Then read ${CLAUDE_PLUGIN_ROOT}/reference/work-model.md and resolve the mode before any gh call — it decides where you read the diff and where you post the review.

Then read ${CLAUDE_PLUGIN_ROOT}/reference/review-rigor.md and review with the posture it defines — it is the review counterpart to the personas' advise-not-block posture during implement-issue.

Review the code as written; in local self-review, judge the diff against the standards, not the implementation rationale.

1. Read the diff

• GitHub mode: gh pr view <N> and gh pr diff <N>.
• Local mode: read the task's branch from <ledger.dir>/<slug>/task.md, then git diff <base>...<branch> inside the worktree (<base> is the branch point).

2. Analyze the change

Right-size the rigor to the diff (mirroring how implement-issue right-sizes team deliberation):

• Routine diff — the default. A contained change, a handful of files, low blast radius: review it yourself in one focused pass against the checklist below. A change that merely spans a couple of packages is still routine — don't spin up five subagents for an ordinary multi-file edit.

• Substantial / risky diff — convene the advisory panel only when the change is genuinely high-stakes: it touches security/auth, concurrency, or a public API / output contract, OR it is large (roughly 10+ files, or a core-subsystem rewrite). Then spawn each persona in team.personas as a subagent (via Task / TeamCreate), give each the diff + the standards, and charge each to attack the change from their lens and return file:line findings with severities:

  • architect — convention/layering/contract violations; logic in the wrong place.
  • pragmatist — regressions, edge cases the change misses, blast radius, new failure modes.
  • perf-analyst — hot-path cost, added queries/allocations, concurrency hazards.
  • product-advocate — observable-behavior / output-shape / UX regressions; does it actually address what was asked?
  • visionary — tech debt or a bad pattern the change locks in.

  (The lenses above mirror agents/*.md; the review posture lives in review-rigor.md — edit posture there, not here. A custom persona configured in team.personas is convened too, with the generic "attack from your lens" charge.)

  You are the lead: collect their findings, dedup, and reconcile divergence per review-rigor.md — surface disagreement, weigh by blast radius, and flag a high-stakes split for the human to decide rather than silently averaging.

Check against the project's documented standards; absent project-specific rules, apply these widely-accepted ones. In a solo review you apply this whole checklist; in a panel review each persona applies the slice that fits their lens and you (the lead) own the full checklist as the baseline:

• Correctness & safety — obvious bugs, unhandled errors, race conditions, resource leaks, off-by-one / null handling.
• Security — injection (string-built queries/commands), secrets committed or logged, unvalidated input on a trust boundary, auth/permission gaps. Calibrate: flag a security finding only when the change creates a concrete, actionable risk or removes a real safety check — not to look thorough. Security review should not cripple legitimate functionality.
• Consistency — follows the patterns and layering the surrounding code uses.
• Tests & docs — behavior changes covered by tests; user-facing changes documented, per the project's norms.
• Prohibited changes — anything matching guardrails.protected_paths (migrations, infra, auth, secrets, CI) is a blocker flagged for human review, not something to wave through.

Classify each finding: blocker (must fix), warning (should fix), or suggestion (optional). Cap at the ~20 most important findings — blockers first.

Verify before you flag. Before you keep a blocker, re-read the cited code and its surrounding context to confirm the problem is real (review-rigor.md). Drop or downgrade any finding you can't confirm against the code — a false blocker requests changes a human must refute, or sends the review→fix loop chasing a non-bug.

Sweep the bug class. When a confirmed finding reveals a repeated pattern (a missing guard, an un-updated caller, an unsafe idiom), scan the rest of the diff for sibling instances and flag them together as one finding with every file:line. Don't flag instance #1 and leave the fix loop to rediscover the rest one round at a time.

3. Clean up your own stale reviews

(GitHub mode only — skip in local mode; local reviews are overwritten in review.md.)

Remove prior crew reviews so the PR doesn't accumulate clutter:

# delete previous summary comments crew posted
gh api "repos/{owner}/{repo}/issues/<N>/comments" \
  --jq '.[] | select((.user.login | endswith("[bot]")) and (.body | startswith("## Code Review Summary"))) | .id' \
  | while read -r id; do gh api "repos/{owner}/{repo}/issues/comments/$id" -X DELETE; done

# dismiss previous CHANGES_REQUESTED reviews crew left
gh api "repos/{owner}/{repo}/pulls/<N>/reviews" \
  --jq '.[] | select((.user.login | endswith("[bot]")) and .state == "CHANGES_REQUESTED") | .id' \
  | while read -r id; do
      gh api "repos/{owner}/{repo}/pulls/<N>/reviews/$id/dismissals" -f message="Superseded by new review"
    done

4. Post the review

Local mode: write findings to <ledger.dir>/<slug>/review.md and set task.md status to changes_requested (if any blockers/warnings) or approved (only suggestions or clean). Each finding gives file:line, severity, category, and a constructive fix, so respond-to-review can act on it. Then stop — the rest of this step is github-only.

## Review — iteration <K>  (status: changes_requested)
**Verdict:** changes-requested
### Blockers
- `path/to/file:42` — **(Security)** … constructive fix …
### Warnings
- `path/to/file:8` — **(Consistency)** …
### Suggestions
- …

GitHub mode — post to the PR:

If there are blockers or warnings — submit REQUEST_CHANGES with inline comments on the affected lines:

gh api "repos/{owner}/{repo}/pulls/<N>/reviews" \
  -f event="REQUEST_CHANGES" \
  -f body="## Code Review Summary
Found N blocker(s) and M warning(s).
Verdict: changes-requested." \
  -f 'comments[0][path]=path/to/file' \
  -f 'comments[0][line]=42' \
  -f 'comments[0][body]=**Blocker (Security)**: … constructive fix …'

If only suggestions or nothing — post an approving comment:

gh pr comment <N> --body "## Code Review Summary

No blockers or warnings found. K suggestion(s) noted.
Verdict: approve.

**Suggestions:**
- \`path/to/file:8\` — …"

Rules

• Always prefix the review body with ## Code Review Summary.
• End the summary with an explicit verdict — approve (clean / suggestions only) or changes-requested (blockers or warnings to fix). A protected_paths change or a high-stakes split decision is a blocker that names the call for a human to make — crew reviews, it never decides the merge.
• Inline comments for blockers/warnings, on the exact line.
• Each finding states severity, category, file:line, and a constructive suggestion — and is one you verified against the code (review-rigor.md), not a guess.
• Never auto-merge — a human approves and merges.
• Never modify files — review and comment only.
