Watch it fail. Write minimal code to pass.\n\n**Core principle:** Watch the test fail. Only then is it proven to test the right thing.\n\n**Violating the letter of the rules is violating the spirit of the rules.**\n\n## When to Use\n\n**Always:**\n- New features\n- Bug fixes\n- Refactoring\n- Behavior changes\n\n**Exceptions (skip TDD only for these; otherwise follow the full TDD cycle):**\n- Throwaway spikes that will never be merged (branch must be deleted before implementation begins; any code carried forward requires full TDD)\n- Generated code (scaffolded, not behavior-bearing)\n- Configuration-only changes\n\nThinking \"skip TDD just this once\"? Stop. That's rationalization.\n\n## The Iron Law\n\n```\nNO PRODUCTION CODE WITHOUT A FAILING TEST FIRST\n```\n\nWrite code before the test? Delete it. Start over.\n\n**No exceptions:**\n- Don't keep it as \"reference\"\n- Don't \"adapt\" it while writing tests\n- Don't look at it\n- Delete means delete\n\nImplement fresh from tests. Period.\n\n## Choosing Test Type\n\nHonor any integration or E2E coverage explicitly required by the task's supplied requirements or test\nplan. For behavior without a higher-layer requirement, prove it at the lowest layer that can adequately\ndetect the relevant failure:\n\n- **Unit** — pure logic, validation, transformations, calculations. No I/O, no wiring. Fast (<100ms).\n- **Integration** — components wired together: database queries, middleware chains, API clients, config reaching runtime. If the bug would only manifest when components connect, it needs an integration test.\n- **E2E** — critical user flows only (login, checkout, onboarding). Expensive, slow, flaky-prone. Don't use for logic that can be tested at a lower level.\n\nDo not substitute a unit test for required integration or E2E coverage, and do not duplicate the\nsame assertion at multiple layers without a distinct risk. When implementation tasks are supplied,\nkeep each automated obligation in the same task as the behavior it protects.\n\nWhen in doubt: can you test it with a function call and an assertion? Unit test. Does the risk exist only\nwhen real components connect? Integration test. Does only a complete public journey prove it? E2E test.\n\n## From Spec to Tests\n\nTrace each specification scenario to automated coverage and write the relevant failing test before\nimplementation. A scenario normally becomes one focused test at the lowest adequate layer, but an\nexplicit integration or E2E requirement controls when higher-layer coverage is required. Do not\nreproduce the same scenario mechanically at every layer.\n\n**Spec scenario:**\n> **WHEN** a user with an expired session requests a protected resource\n> **THEN** they receive a 401 and a redirect to login\n\n**Test:**\n```typescript\ntest('expired session returns 401 with login redirect', async () => {\n  const session = createExpiredSession();\n  const response = await requestProtectedResource(session);\n  expect(response.status).toBe(401);\n  expect(response.headers.location).toBe('/login');\n});\n```\n\nOne test per scenario, one scenario per behavior. If a scenario needs multiple assertions, that's fine — but if it needs multiple *setups*, split it. If the spec numbers its criteria (AC-1, R-001, etc.), reference the ID in the test name or comment for traceability. (Note: the spec skill does not generate IDs by default — IDs are an optional custom extension you may add to your spec for traceability.)\n\n## Red-Green-Refactor\n\n```dot\ndigraph tdd_cycle {\n    rankdir=LR;\n    red [label=\"RED\\nWrite failing test\", shape=box, style=filled, fillcolor=\"#ffcccc\"];\n    verify_red [label=\"Verify fails\\ncorrectly\", shape=diamond];\n    green [label=\"GREEN\\nMinimal code\", shape=box, style=filled, fillcolor=\"#ccffcc\"];\n    verify_green [label=\"Verify passes\\nAll green\", shape=diamond];\n    refactor [label=\"REFACTOR\\nClean up\", shape=box, style=filled, fillcolor=\"#ccccff\"];\n    next [label=\"Next\", shape=ellipse];\n\n    red -> verify_red;\n    verify_red -> green [label=\"yes\"];\n    verify_red -> red [label=\"wrong\\nfailure\"];\n    green -> verify_green;\n    verify_green -> refactor [label=\"yes\"];\n    verify_green -> green [label=\"no\"];\n    refactor -> verify_green [label=\"stay\\ngreen\"];\n    verify_green -> next;\n    next -> red;\n}\n```\n\n### RED - Write Failing Test\n\nWrite one minimal test showing what should happen.\n\n**Good:**\n```typescript\ntest('retries failed operations 3 times', async () => {\n  let attempts = 0;\n  const operation = () => {\n    attempts++;\n    if (attempts < 3) throw new Error('fail');\n    return 'success';\n  };\n\n  const result = await retryOperation(operation);\n\n  expect(result).toBe('success');\n  expect(attempts).toBe(3);\n});\n```\n_Clear name, tests real behavior, one thing_\n\n**Bad:**\n```typescript\ntest('retry works', async () => {\n  const mock = jest.fn()\n    .mockRejectedValueOnce(new Error())\n    .mockRejectedValueOnce(new Error())\n    .mockResolvedValueOnce('success');\n  await retryOperation(mock);\n  expect(mock).toHaveBeenCalledTimes(3);\n});\n```\n_Vague name, tests mock not code_\n\n**Requirements:**\n- One behavior\n- Clear name\n- Real code (no mocks unless unavoidable)\n\n### Verify RED - Watch It Fail\n\n**MANDATORY. Never skip.**\n\n```bash\nnpm test path/to/test.test.ts\n```\n\nConfirm:\n- Test fails (not errors)\n- Failure message is expected\n- Fails because feature missing (not typos)\n\n**Test passes?** You're testing existing behavior. Fix test.\n\n**Test errors?** Fix error, re-run until it fails correctly.\n\n### GREEN - Minimal Code\n\nWrite simplest code to pass the test.\n\n**Good:**\n```typescript\nasync function retryOperation<T>(fn: () => Promise<T>): Promise<T> {\n  for (let i = 0; i < 3; i++) {\n    try {\n      return await fn();\n    } catch (e) {\n      if (i === 2) throw e;\n    }\n  }\n  throw new Error('unreachable');\n}\n```\n_Just enough to pass_\n\n**Bad:**\n```typescript\nasync function retryOperation<T>(\n  fn: () => Promise<T>,\n  options?: {\n    maxRetries?: number;\n    backoff?: 'linear' | 'exponential';\n    onRetry?: (attempt: number) => void;\n  }\n): Promise<T> {\n  // YAGNI\n}\n```\n_Over-engineered_\n\nDon't add features, refactor other code, or \"improve\" beyond the test. Never add test-only methods to production classes — put test helpers in test utilities.\n\n### Verify GREEN - Watch It Pass\n\n**MANDATORY.**\n\n```bash\nnpm test path/to/test.test.ts\n```\n\nConfirm:\n- Test passes\n- Other tests still pass\n- Output pristine (no errors, warnings)\n\n**Test fails?** Fix code, not test.\n\n**Other tests fail?** Fix now.\n\n### REFACTOR - Clean Up\n\nAfter green only:\n- Remove duplication\n- Improve names\n- Extract helpers\n\nKeep tests green. Don't add behavior.\n\n### Repeat\n\nNext failing test for next feature.\n\n## Why Order Matters (Common Rationalizations)\n\n**\"I'll write tests after\"** — Tests written after pass immediately. That proves nothing. Tests-after are biased by your implementation: you test what you built, not what's required. Test-first forces you to see failure, proving the test catches something real.\n\n**\"Already manually tested\"** — Ad-hoc, no record, can't re-run, can't prove edge cases. Automated tests are systematic and repeatable.\n\n**\"Deleting X hours of work is wasteful\"** — Sunk cost fallacy. Keeping unverified code is the real waste. Delete and rewrite with TDD gives high confidence; bolting tests onto existing code gives false confidence.\n\n**\"TDD is dogmatic / too slow\"** — TDD is faster than debugging in production. It finds bugs before commit, prevents regressions, documents behavior, and enables safe refactoring.\n\n**\"Keep as reference, write tests first\"** — You'll adapt it. That's testing after with extra steps. Delete means delete.\n\n**\"Hard to test\"** — Listen to the test. Hard to test = hard to use. Simplify the design.\n\nIf you catch yourself rationalizing, delete code and start over with TDD.\n\n## Example: Bug Fix\n\n**Bug:** Empty email accepted\n\n**RED**\n```typescript\ntest('rejects empty email', async () => {\n  const result = await submitForm({ email: '' });\n  expect(result.error).toBe('Email required');\n});\n```\n\n**Verify RED**\n```bash\n$ npm test\nFAIL: expected 'Email required', got undefined\n```\n\n**GREEN**\n```typescript\nfunction submitForm(data: FormData) {\n  if (!data.email?.trim()) {\n    return { error: 'Email required' };\n  }\n  // ...\n}\n```\n\n**Verify GREEN**\n```bash\n$ npm test\nPASS\n```\n\n**REFACTOR**\nExtract validation for multiple fields if needed.\n\n## Verification Checklist\n\nBefore marking work complete:\n\n- [ ] Every spec scenario has a test\n- [ ] Every new function/method has a test\n- [ ] Watched each test fail before implementing\n- [ ] Each test failed for expected reason (feature missing, not typo)\n- [ ] Wrote minimal code to pass each test\n- [ ] All tests pass\n- [ ] Output pristine (no errors, warnings)\n- [ ] Tests use real code (mocks only if unavoidable)\n- [ ] Edge cases and errors covered\n\nCan't check all boxes? You skipped TDD. Start over.\n\n## When Stuck\n\n| Problem | Solution |\n|---------|----------|\n| Test too complicated | Design too complicated. Simplify interface. |\n| Must mock everything | Code too coupled. Use dependency injection. |\n| Test setup huge | Extract helpers. Still complex? Simplify design. |\n| Mock setup > test logic | Understand real method's side effects before mocking. Mock at the lowest level necessary. Consider integration tests instead. |\n\n## Final Rule\n\n```\nProduction code → test exists and failed first\nOtherwise → not TDD\n```\n","tagline":"Enforces test-driven development for feature work, bug fixes, and refactoring, activating for requests such as \"implement\", \"fix\", \"add feature\", \"write tests first\", or \"TDD\".","category":"coding-agents","commerce":{"type":"unknown","billing":"unknown","amount":null,"currency":null,"sourceUrl":null,"checkedAt":null,"runtime":"unknown","purchaseUrl":null,"checkout":"external","purchaseRequiresUserConsent":true},"tags":["agent-skill"],"author":"Codagent-AI","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"Codagent-AI/agent-skills","creatorName":"Codagent-AI","creatorUrl":"https://github.com/Codagent-AI","sourceUrl":"https://github.com/Codagent-AI/agent-skills/tree/main/skills/implement-with-tdd","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/codagent-ai-implement-with-tdd#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
