TDD Review: Red/Green/Refactor Plan

Language

Read blueprint/.config.yml → language. If auto, detect from the user's messages. All generated content MUST be in the detected language. Skill instructions stay in English — only output changes.

TDD variant of /plan-review. Restructures the plan to follow Red/Green/Refactor: all tests written first (failing), implementation makes them pass, coverage phase reaches 100%.

This skill ONLY restructures the plan file — NEVER write actual test or implementation code.

/plan → /bp-tdd-review → [clear context] → /plan-approved → /plan-check → /pr → /finish

Critical Rules

• You MUST read the plan file AND references/team-execution.md at Step 1. NEVER fabricate plan details.
• You MUST use mcp__sequential-thinking__sequentialthinking at Step 1. NEVER skip.
• You MUST inject Phase 0 (test writing) before ALL implementation phases.
• Phase 0 worker MUST confirm tests FAIL before marking complete.
• NEVER allow implementation in Phase 0 — write tests only.
• You MUST add a final Coverage phase targeting 100%.
• Mark ALL tasks [H]/[S]/[O]. NEVER leave unmarked tasks.
• Phase 0 test tasks MUST be derived from the plan's actual models, endpoints, and features — NEVER use generic placeholders.
• Every Phase 0 test task MUST map to a corresponding GREEN implementation task, and vice versa.

Testing Conventions — MANDATORY

• Framework: Use the project's test framework as detected from configuration
• NEVER mock what you can test — real models, real DB, only mock external HTTP
• Use parameterized tests / data providers for multiple cases where supported

Step 1: Parallel Data Gather + Validate — MANDATORY

Run these simultaneously:

1. blueprint meta — get plan metadata
2. Read the full plan file (from meta output)
3. Read references/team-execution.md for execution mode selection

Then use mcp__sequential-thinking__sequentialthinking to validate completeness, dependencies, testability, file conflicts. During validation, extract a list of all models, endpoints, services, and features from the plan — this list drives Phase 0 test naming.

DO NOT proceed without reading the plan file AND team-execution.md.

Step 2: Add Session Entry

Add ${CLAUDE_SESSION_ID} to the plan file:

• Work Sessions: `${CLAUDE_SESSION_ID}` DD/MM/YYYY HH:MM - TDD review — `claude -r ${CLAUDE_SESSION_ID}`
• YAML sessions: array: - id: "${CLAUDE_SESSION_ID}" date: "DD/MM/YYYY HH:MM" note: "TDD review"

Step 3: Mark Task Complexity

Mark ALL tasks: [H] (simple), [S] (medium), [O] (complex/rare). Default to [H].

Step 4: Inject Phase 0 — Write All Tests (RED) — MANDATORY

Insert Phase 0 at TOP of Phases section. Derive test class names directly from the plan's models, endpoints, and features extracted in Step 1. Each test task must target a specific entity from the plan.

Example (adapt to actual plan content):

### Phase 0: Write All Tests (RED)

> **TDD:** Write ALL tests before any implementation. Tests MUST fail at the end of this phase.

- [ ] [S] Write Feature tests: CreateOrderTest, UpdateOrderStatusTest (from Phase 1 tasks)
- [ ] [S] Write Unit tests: OrderServiceTest, PricingCalculatorTest (from Phase 2 tasks)
- [ ] [H] Run tests → verify ALL fail (failures expected)
- [ ] [H] Commit: `test: add failing tests for [feature] (RED)`

Naming rule: For each implementation task in the plan that produces testable behavior, create a corresponding test task in Phase 0. Use the format [Model]Test, [Feature]Test, or [Endpoint]Test — derived from the plan, never generic placeholders.

Step 5: Annotate Implementation Phases (GREEN) + Verify RED/GREEN Mapping

Add (GREEN) annotation to each implementation phase.

After annotating, verify 1:1 mapping: Walk through every Phase 0 test task and confirm there is a GREEN implementation task that will make those tests pass. If a test task has no corresponding implementation task, add one. If an implementation task has no corresponding RED test, add a test task to Phase 0. Document the mapping as a comment block in the plan:

<!-- RED/GREEN mapping:
  Phase 0: CreateOrderTest → Phase 1: Create Order model + migration + controller
  Phase 0: OrderServiceTest → Phase 2: Implement OrderService
-->

Step 6: Inject Final Phase — Coverage & Refactor — MANDATORY

### Phase N+1: Coverage & Refactor (REFACTOR)

> **TDD:** Target 100% coverage on files touched by this feature.

- [ ] [S] Run coverage — identify uncovered lines
- [ ] [S] Write additional tests for uncovered branches
- [ ] [H] Confirm all green
- [ ] [H] Run code formatting
- [ ] [H] Commit: `test: complete 100% coverage (REFACTOR)`

Step 7: Determine Execution Strategy + Update Header

Phase 0 (RED) is ALWAYS Round 1. Coverage is ALWAYS last round. Implementation phases follow standard mode selection.

Update plan header:

> **Mode:** TDD
> **Coverage Target:** 100%
> **Status:** Approved

Step 8: Pre-Commit Checklist + Commit

git add blueprint/ && git commit -m "plan: tdd-review NNNN-<description>"

STOP. Use AskUserQuestion:

• "Got it — clearing context now"
• "Let me adjust the test list first"

Rules

• Phase 0 is ALWAYS first round
• Coverage phase is ALWAYS last round
• Workers in Phase 0 write ONLY tests
• Workers in GREEN phases implement ONLY what failing tests require
• Professional worker naming: worker-1, worker-2, team-alpha, team-beta

Use $ARGUMENTS as plan file path if provided.
