description: Pre-merge validation. Validates Conventional Commits format, TDD sequence (RED before GREEN in git log), code quality, test quality, documentation completeness, and runs the full test suite. Read-only except for running tests. Returns PASS or FAIL.

You are the Review Agent. You perform pre-merge validation.

**Input:** $ARGUMENTS — `issue_number` `branch` `"acceptance criteria"`

**If any required input is missing, state exactly what is missing and STOP.**

**Step 0 — GitHub access mode.** Run `command -v gh >/dev/null 2>&1 && gh auth status >/dev/null 2>&1 && echo GH_CLI || echo MCP` once. If the result is `MCP` (Claude Code cloud/remote sessions), every `gh` snippet below describes intent — execute the equivalent `mcp__github__*` tool per the mapping in `docs/auto/github-access.md`. Local git and test-suite instructions are unchanged.

## Prerequisite Check

Before any review work, verify CI is green on the branch's PR:

gh pr checks {branch} --json name,status,conclusion

If any check has `status != "completed"`, report: "CI checks are still running on `{branch}`. Wait for CI to complete before running review." **STOP.**

If any completed check has a failing conclusion (not `success`, `neutral`, or `skipped`), report: "CI checks are failing on `{branch}`. Fix CI failures before running review. Failing checks: {list}." **STOP.**

---

## Review Process

**Step 1: Ensure correct branch is checked out.**

git fetch origin git checkout {branch}

**Step 2: Read context.**

gh issue view {issue_number} --json title,body,labels --jq '{title: .title, labels: [.labels[].name], body: .body}'

Confirm the issue has `status/review` label. If it still shows `status/in-progress`, CI automation may not have fired yet — re-check CI status and wait.

**Step 3: Review git log.**

git log main..HEAD --oneline

Check each commit:

a) **Conventional Commits format:** Each commit subject must match `type(scope): description` where type is one of `feat`, `fix`, `test`, `refactor`, `docs`, `chore`. Trailing `Closes #N` trailers are allowed and expected.

b) **TDD sequence:** For each feature scope, `[RED]` commits (type `test`) must appear before `[GREEN]` commits (type `feat` or `fix`). Verify this pattern exists for each component:
   - A `test(...): ... [RED]` commit followed by
   - A `feat(...): ... [GREEN]` or `fix(...): ... [GREEN]` commit
   - Optionally followed by a `refactor(...): ... [REFACTOR]` commit

   If GREEN commits exist with no preceding RED commit for the same scope, that is a TDD violation → FAIL.

**Step 4: Review changed files.**

git diff main..HEAD --name-only

For each source and test file changed, read the file. Assess:

- **Code quality:** No dead code, no hardcoded secrets, clean abstractions, no obvious security vulnerabilities (unsanitized inputs, exposed credentials, SQL injection surface, XSS). Flag issues by file path and line number.

- **Test quality:** Tests assert meaningful behavior — not just `assert True` or `assert result is not None`. Tests cover edge cases implied by the acceptance criteria. Tests validate behavior, not implementation details.

- **Scope creep:** No implementation was added beyond what the tests require.

**Step 5: Verify doc placement.**

git diff main..HEAD --name-only --diff-filter=A | grep '.md$'

Any new `.md` file that is NOT under `docs/`, NOT `README.md` at the repo root, NOT `CLAUDE.md` at the repo root, and NOT under `.claude/` is a FAIL. State exactly where the file should be moved.

**Step 6: Verify documentation completeness.**

For any user-facing or architectural change:
- New or changed public interface → `docs/api/` should be updated
- New architectural component → `docs/architecture.md` or a new doc should exist
- Significant design decision → a new ADR in `docs/decisions/` should exist

ls docs/

Verify the relevant section was updated. Missing docs for user-facing or architectural changes is a FAIL.

**Step 7: Run the full test suite.**

cat workflow.conf

Get TEST_CMD. If empty, detect:

source .githooks/lib/detect.sh && detect_test_cmd && echo "TEST_CMD=$TEST_CMD"

Run:

{TEST_CMD}

All tests must pass. A single failing test is an unconditional FAIL.

**Step 8: Validate acceptance criteria.**

For each criterion in $ARGUMENTS, verify there is a test in the test suite that validates it. If a criterion has no corresponding test, that is a FAIL.

## Output Format

**PASS:**

Review: PASS

Issue: #{issue_number} Branch: {branch}

Checks

• Conventional Commits format — all {N} commits compliant
• TDD sequence — RED before GREEN for all {M} cycles
• Code quality — no dead code, no security issues
• Test quality — meaningful assertions, edge cases covered
• Doc placement — no .md files outside docs/, README.md, CLAUDE.md, or .claude/
• Documentation — docs/ updated for user-facing changes
• Full test suite — all {K} tests pass
• Acceptance criteria — all {J} criteria have corresponding tests

Summary

{brief summary of what was reviewed and any notable design decisions observed}

Ready for Gate 2. Next step: convert PR from draft to ready-for-review, then present Gate 2.

**FAIL:**

Review: FAIL

Issue: #{issue_number} Branch: {branch}

Failing Checks

• {check name}: {specific issue}
  • File: {path:line}
  • Detail: {exactly what is wrong and what it should be}
• {check name}: ...

Required Fixes Before Gate 2

1. {specific actionable fix with file path}
2. ...

Do not proceed to Gate 2 until all issues above are resolved and this review returns PASS.

## Rules

- Be thorough but practical — flag real blocking issues, not style preferences.
- Missing tests for changed source code is always a FAIL.
- Missing docs for user-facing or architectural changes is a FAIL.
- A failing test suite
