Signalcompose Claude Tools Pr Review Team

PR Review Team

MANDATORY: This skill runs a complete review-fix-re-review loop using Subagents (NOT Agent Teams).

The leader MUST:

1. Initialize state and gather PR context (Step 1)
2. Launch 4 parallel reviewer subagents (Step 2)
3. Run CI checks via script (Step 3)
4. Integrate results + security checklist (Step 4)
5. If critical > 0 OR important > 0 OR security != "all_pass": enter fix loop (Step 5)
6. Report results and cleanup (Step 6)

🔴 Stop hooks verify workflow completion. Skipping steps will block the stop request.

Step 1: Initialize & Identify Target PR

Initialize State

Run immediately (creates the active-review flag file for Stop hook detection):

bash ${CLAUDE_PLUGIN_ROOT}/scripts/pr-review-state.sh init <PR番号>

Resolve PR

• If user specified: use that number
• Otherwise: gh pr view --json number --jq '.number' 2>/dev/null

Gather Context

• File overview: gh pr diff <PR番号> --name-only
• Base branch: git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's|refs/remotes/origin/||' (fallback: main)
• Test command: detect from package.json, Makefile, pytest.ini, etc.
• Project rules: read project's CLAUDE.md if present

Note: gh commands may require dangerouslyDisableSandbox: true for TLS issues.

Step 2: Parallel Review (Subagents)

MANDATORY: Launch ALL 4 reviewers in a SINGLE message using parallel Agent tool calls. Do NOT use TeamCreate or Task tool. Use the Agent tool directly.

Launch in parallel (one message, 4 Agent tool calls):

1. Agent(subagent_type: "pr-review-toolkit:code-reviewer", model: "sonnet", prompt: "...")
2. Agent(subagent_type: "pr-review-toolkit:silent-failure-hunter", model: "sonnet", prompt: "...")
3. Agent(subagent_type: "pr-review-toolkit:pr-test-analyzer", model: "sonnet", prompt: "...")
4. Agent(subagent_type: "pr-review-toolkit:comment-analyzer", model: "haiku", prompt: "...")

Results return automatically. No shutdown procedure needed.

Review criteria: include ${CLAUDE_PLUGIN_ROOT}/skills/review-commit/references/review-criteria.md path in each agent prompt — agents read criteria, leader handles integration.

Agent Launch Failure Handling

Update State

bash ${CLAUDE_PLUGIN_ROOT}/scripts/pr-review-state.sh set <PR番号> reviewers_done true
bash ${CLAUDE_PLUGIN_ROOT}/scripts/pr-review-state.sh set <PR番号> phase reviewed

Step 3: CI Check

Run the CI wait script (requires dangerouslyDisableSandbox: true):

bash ${CLAUDE_PLUGIN_ROOT}/scripts/wait-ci-checks.sh <PR番号>

Parse the STATUS line from output:

• PASS: All checks passed
• FAIL: Get failure details with gh run view <run-id> --log-failed
• TIMEOUT: Continue review, note "CI: PENDING (timed out)" in report
• ERROR: Retry with dangerouslyDisableSandbox: true

Also collect review comments:

gh pr view <PR番号> --json comments --jq '.comments[].body'

HEAD Filtering

Avoid sending already-fixed issues to the fixer:

• For each CI issue or review comment, check if the referenced line still exists in current HEAD
• Mark modified/removed lines as "already addressed" — do NOT send to fixer

Step 4: Integrate & Prepare Fixer Message

🔴 VIOLATION — Direct Editing Prohibited ALL fixes MUST be delegated to the fixer subagent in Step 5. Using Edit/Write tools directly to apply fixes is a workflow violation. The Stop hook will block completion if the fixer agent was not used.

🔴 MANDATORY — Security Checklist Read NOW (Stop hook verifies this was read): ${CLAUDE_PLUGIN_ROOT}/skills/pr-review-team/references/security-checklist.md

bash ${CLAUDE_PLUGIN_ROOT}/scripts/pr-review-state.sh set <PR番号> security_done true

Fixer Message Template

Structure ALL findings into one single message (split messages prohibited):

## Critical Issues
- Source: <reviewer-name>
- File: <path>:<line>
- Issue: <description>

## Important Issues
- Source: <reviewer-name>
- File: <path>:<line>
- Issue: <description>

## Security Checklist Failures
- Check: <checklist-item>
- File: <path>:<line>
- Issue: <description>

## Already Addressed (informational — do NOT fix)
- Source: <reviewer-name or CI>
- Reason: Line modified/removed in current HEAD

Security Checklist: ALL PASS (N items checked) / HAS FAILURES (list)

If all pass: "Security Checklist: ALL PASS (N items checked)"

Step 5: Fix Loop

🔴 MANDATORY: If Step 4 produced ANY critical or important issues, or security failures, this step MUST execute.

🔴 VIOLATION — Re-review Required After Fixes After fixer applies fixes, ALL 4 reviewers MUST be re-invoked (same parallel pattern as Step 2). Skipping re-review is a workflow violation.

MAX_ITERATIONS=3

FOR iteration = 1 TO MAX_ITERATIONS:
  1. Spawn fixer subagent:
     Agent(subagent_type: "general-purpose", model: "sonnet", prompt: "<all findings>")
     Send ALL findings in a single prompt (Critical + Important + Security failures)

  2. Fixer applies fixes and runs tests
     IF tests fail after 2 retries → report to user, do NOT merge, BREAK

  3. Re-review: Launch ALL 4 reviewers again (parallel Agent tool calls, same as Step 2)

  4. Collect fresh counts: fresh_critical, fresh_important, fresh_security

  5. Update state:
     bash ${CLAUDE_PLUGIN_ROOT}/scripts/pr-review-state.sh set <PR番号> fixer_done true
     bash ${CLAUDE_PLUGIN_ROOT}/scripts/pr-review-state.sh set <PR番号> iterations <N>
     bash ${CLAUDE_PLUGIN_ROOT}/scripts/pr-review-state.sh set <PR番号> final_critical <count>
     bash ${CLAUDE_PLUGIN_ROOT}/scripts/pr-review-state.sh set <PR番号> final_important <count>

  6. IF fresh_critical = 0 AND fresh_important = 0 AND fresh_security = "all_pass" → BREAK
END FOR

If iteration limit reached with remaining issues: report to user, do NOT merge.

Step 6: Report & Cleanup

Report summary:

• Issues found / fixed / remaining
• Iterations performed
• Security checklist status
• CI status (including any PENDING timeouts)
• Agents that failed to launch (if any)

Do NOT merge — wait for user's explicit instruction.

Cleanup

bash ${CLAUDE_PLUGIN_ROOT}/scripts/pr-review-state.sh cleanup <PR番号>

No shutdown procedure needed — subagents complete automatically.
