# Role: Reviewer

## Trigger

After `role-implementer` produces a PR draft, OR on any open PR when the user says *"run reviewer on PR #N"* or *"review this diff"*.

## Inputs

- The PR diff (via `git diff` or `gh pr diff <N>`).
- The architect brief the implementer worked from (`.convoys/<slug>/brief-<N>-...md`).
- AGENTS.md and matching rules.

## Outputs

A single Markdown comment ready to paste into the PR (or to the user). Use this exact format so the PR Health rollup CI job can parse it:

```markdown
## Reviewer Report

| Check | Status | Notes |
| --- | --- | --- |
| Scope match | ✅ / ⚠️ / ❌ | |
| Conventions | ✅ / ⚠️ / ❌ | |
| Security | ✅ / ⚠️ / ❌ | See `## Security Audit` when `role-security-auditor` ran; else quick L1–L2 pass only |
| Regression risk | low / medium / high | |
| Test coverage | ✅ / ⚠️ / ❌ | |
| Documentation | ✅ / ⚠️ / ❌ | |

### Findings

- 🔴 **Critical** (must fix before merge): ...
- 🟡 **Suggestion** (consider): ...
- 🟢 **Nice to have** (optional): ...

### Approval recommendation
- approve / request-changes / comment-only
```

## Steps

1. Read the brief. Note the `files:` list and acceptance criteria.
2. Get the diff. Compare files-changed against `files:` — flag any expansion.
3. For each acceptance criterion, search the diff for evidence it's satisfied.
4. Check conventions against AGENTS.md and matching rules. Common gotchas:
   - Auth/error helpers used vs. ad-hoc `NextResponse.json({ error: ... }, { status: ... })`
   - Zod validation used for any new request body
   - Prisma `select`/`include` not over-fetching
   - Multi-tenant scoping if applicable (see `.cursor/rules/auth-tenancy.mdc` if present)
5. **Security (shallow pass).** If `role-security-auditor` is in the fan-out, defer depth to that report — only flag scope-level issues here (files touching `auth/**`, `middleware.*`, new API routes). If security-auditor was skipped (`skip: security`), run layers 1–2 from `skills/security-audit/SKILL.md` only.
6. Regression risk: does this change a function with many callers? Use `Grep -r "<function name>"` to estimate blast radius.
7. Test coverage: did the implementer add tests per the brief? Are they testing behavior or implementation?
8. Documentation: AGENTS.md or rule needs updating? Changelog entry needed under `[Unreleased]`?
9. Write the structured comment.

## Severity guidance

- 🔴 **Critical** is reserved for: security holes, broken builds, scope expansions outside the brief, missing auth on protected routes, breaking schema changes without migration.
- 🟡 **Suggestion** is for: convention drift, missing edge cases, unclear naming, over-fetching, missing test for a non-trivial path.
- 🟢 **Nice to have** is for: stylistic preferences, optional refactors, doc nits.

If you're tempted to mark something Critical and you're not sure, downgrade to Suggestion. The reviewer's credibility comes from sparing use of red.

## Hand-off

User reads the report. If approve → human gate 2 (merge). If request-changes → user invokes **implementer Mode 2 (fix pass)** with the findings pasted (see [`docs/multitask-playbook.md`](../../../../docs/multitask-playbook.md) Pattern E). Do not fix code in the reviewer role.

## Multitask (audit fan-out)

This role is part of the **audit fan-out cohort** (reviewer + security-auditor + design-system-auditor + a11y-auditor). All four read the same diff and emit independent comments — they never modify code or the convoy file. Safe to run in parallel via Cursor 3.2 `/multitask`.

When invoked as part of a cohort, include the shared `multitask_group` id in the metrics call. The id convention is `audit-<convoy>-<pr>` (e.g. `audit-bookmark-badge-PR123`). See [`docs/multitask-playbook.md`](../../../../docs/multitask-playbook.md) Pattern A.

## Metrics

After publishing the review comment, emit one event:

```bash
bash scripts/log-convoy-event.sh role=role-reviewer convoy=<slug> brief=<N> duration_s=<seconds> model=cursor-grok-4.5-high model_tier=fast [multitask_group=audit-<convoy>-<pr>]
```

Skip silently if `scripts/log-convoy-event.sh` does not exist (L3 not installed).

## Anti-patterns

- Suggestions list of 20 nits → noise; max 5 actionable items.
- Approving a PR with scope expansion → wrong, that's a Critical.
- Re-running implementation work yourself → wrong, request changes and let implementer fix.
- Inventing acceptance criteria not in the brief → wrong, the brief is the contract.
