Success Output

When successful, this agent MUST output:

✅ SKILL COMPLETE: tdd-workflows

TDD Workflow Implemented:
- [x] Test cases written before implementation (Red phase)
- [x] Minimal code written to pass tests (Green phase)
- [x] Code refactored while maintaining passing tests (Refactor phase)
- [x] Test coverage meets target threshold (>80%)
- [x] All tests passing (100% pass rate)

Outputs:
- tests/[module]/test_[feature].py (or .js/.ts)
- src/[module]/[feature].py (or .js/.ts)
- coverage/coverage-report.html (coverage metrics)

Test Quality:
- Test count: [N] tests written
- Coverage: [X]% (target: >80%)
- Pass rate: [X]/[N] (100% required)
- Test types: Unit [X], Integration [Y], E2E [Z]
- Mutation score: [X]% (if applicable)

Completion Checklist

Before marking this agent as complete, verify:

Failure Indicators

This agent has FAILED if:

❌ Implementation code written before tests (violates TDD)
❌ Tests not covering edge cases (only happy path)
❌ Tests are interdependent (shared state causes failures)
❌ Any tests failing (pass rate <100%)
❌ Code coverage below threshold (<80%)
❌ Tests are slow (>1s for unit tests)
❌ Tests are flaky (non-deterministic pass/fail)
❌ Test names unclear (e.g., test1, test_function)
❌ Refactoring skipped (code not cleaned up)
❌ CI/CD not configured to run tests

When NOT to Use

Do NOT use this agent when:

Exploratory coding/prototyping → TDD adds overhead; prototype first, then add tests
Legacy code without tests → Use characterization tests first, then refactor to TDD
UI/UX design iteration → Design workflows don't fit Red-Green-Refactor cycle
Performance optimization → Profile first, optimize, then ensure tests still pass
Documentation-only changes → No code changes = no tests needed
Configuration changes → Config validation tests optional for simple changes
Spike/proof-of-concept work → Throw-away code doesn't justify TDD
Integration with third-party APIs → Use integration tests with mocks, not full TDD cycle

Use alternative approaches:

Legacy code → Characterization tests + gradual refactoring
Prototyping → Build prototype, then test critical paths
UI iteration → Component testing after design stabilizes
Performance → Benchmarking + regression tests

Anti-Patterns (Avoid)

Anti-Pattern	Problem	Solution
Writing implementation first	Not TDD, just "tests after"	Write failing test FIRST, then minimal code to pass
Testing implementation details	Brittle tests break on refactor	Test public interfaces/behavior, not internals
One giant test	Hard to debug failures	One test per behavior (FIRST principles)
Shared state between tests	Flaky, order-dependent tests	Isolate with setup/teardown or fixtures
Not refactoring after green	Technical debt accumulates	Red → Green → Refactor (don't skip!)
Skipping edge cases	Bugs in production	Test happy path AND edge cases/errors
Slow tests (>1s unit tests)	Developers skip running tests	Mock external dependencies, optimize setup
Testing framework code	Wasted effort	Test YOUR code, not library/framework internals
Low coverage accepted (<80%)	Insufficient safety net	Aim for 80%+ line coverage, 100% critical paths
No CI/CD test automation	Manual testing bottleneck	Auto-run tests on commit/PR

Principles

This agent embodies CODITECT automation principles:

#1 Recycle → Extend → Re-Use → Create

Reuse test fixtures and helpers across test suites
Extend existing test patterns for new features
Create new test utilities only when existing patterns insufficient

#2 First Principles

Red → Green → Refactor cycle (core TDD principle)
Tests define behavior specification
Failing test proves test works (Red phase validates test)

#3 Keep It Simple

Minimal code to pass tests (no over-engineering)
One assertion per test (focused, simple tests)
AAA structure (Arrange, Act, Assert)

#5 Eliminate Ambiguity

Descriptive test names (behavior, not implementation)
Explicit assertions (no vague checks)
Clear pass/fail criteria

#6 Clear, Understandable, Explainable

Test names document expected behavior
Test structure reveals intent (AAA pattern)
Coverage reports show gaps

#7 Self-Provisioning

Test framework auto-setup (pytest, jest, etc.)
Coverage tools integrated (coverage.py, jest --coverage)
CI/CD auto-runs tests

#8 No Assumptions

Write test for edge cases (null, empty, large inputs)
Verify preconditions in test setup
Explicit mocking of external dependencies
