tdd-workflow

Test-driven development enforces writing failing tests before implementation. This Skill automates the TDD workflow—RED phase creates integration tests, GREEN phase generates minimal code to pass them, REFACTOR phase reviews quality—coordinating subagents across feature and API development to maintain code reliability.

Yes. This Skill orchestrates the complete TDD cycle: it generates failing integration tests first, creates minimal implementations using existing patterns, then conducts quality checks. Subagent coordination preserves context across all three phases for consistent, tested features.

Integration test scaffolding with in-memory SQLite, trigger keywords to initiate workflows, and subagent coordination (test-writer, code-generator, test-runner, code-reviewer) are prerequisites. The Skill requires full test-suite verification and minimal implementation patterns before deployment.

TDD prevents regressions by requiring tests to pass before code merges. This Skill enforces strict test coverage on all new features and APIs, runs full test-suite verification, and coordinates code review—ensuring every addition is validated against existing behavior.

Yes. This Skill applies to feature additions, API endpoint creation, and implementation tasks across the backend. It guides the RED-GREEN-REFACTOR cycle uniformly, maintaining consistent test-first discipline regardless of task type.
