Test-Driven Development workflow with strict Red-Green-Refactor cycle. Use when developing features with TDD, writing tests before code, or when test-driven approach is needed. MANDATORY order - test cases table BEFORE code, failing tests BEFORE implementation.

SOC 직업 분류 기준
Test API endpoints with proper authorization including Basic Auth and session cookies. Use when testing curl requests, checking API responses, getting 401 Unauthorized, session expired errors, or verifying endpoint behavior after changes.
Implement accumulated improvements from improvements-backlog into AI rules and skills. Use when backlog has 5+ items, weekly rule update cycle, 2+ high priority improvements exist, before important releases, when same error repeated 3+ times, when user says implement improvements/process backlog/update rules from errors.
Fix bugs, errors, exceptions, and unexpected behavior. Use when debugging, fixing errors, handling crashes, or when user mentions bug, error, broken, not working, crash, exception, 500 error, Application error, white screen, TypeError, undefined is not a function, or unexpected behavior.
Analyze Claude Code prompt cache efficiency and costs. Use when user asks about cache performance, token usage, session costs, how much a session cost, wants to optimize prompt caching, when costs seem high, when context window is filling up, or mentions cache-analyzer/cache hits/token costs/session metrics/cost analysis.
Review code for quality, security, and maintainability. Use when reviewing pull requests, examining code changes, doing QA checks, architecture review, or CTO review. Also trigger for COMPLEX tasks affecting more than 5 files, API contract changes, or data migrations.
Create new skills, modify and improve existing skills, create or update AI rules. Use when creating rules, building skills, adding coding standards, updating .claude/rules/ or .claude/skills/, converting Cursor rules to Claude Code, measuring skill performance, running evals, or optimizing skill descriptions.

| description | Test-Driven Development workflow with strict Red-Green-Refactor cycle. Use when developing features with TDD, writing tests before code, or when test-driven approach is needed. MANDATORY order - test cases table BEFORE code, failing tests BEFORE implementation. |
Principle: Red -> Green -> Refactor (STRICT order!)
Fill test cases table BEFORE any code:
## TEST CASES (fill BEFORE implementation!)
| # | Scenario | Input | Expected Output | Type | Status |
|---|----------|-------|-----------------|------|--------|
| 1 | Happy path | <input> | <expected> | Unit | pending |
| 2 | Edge case: empty | [] | <expected> | Unit | pending |
| 3 | Edge case: null | null | Error | Unit | pending |
| 4 | Integration | <context> | <expected> | Integration | pending |
Coverage categories:
STOP: Do NOT proceed to Phase 1 until table is filled!
feature.test.ts)npm test -- --grep "feature"
# Expected: FAIL
STOP: Do NOT write implementation until tests fail!
npm test -- --grep "feature"
# Expected: PASS
STOP: Do NOT refactor until ALL tests are green!
npm test (must stay green)## TDD VERIFICATION
