Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
Writes failing tests first for test-driven development and hands off a strict implementation contract that requires agents to make those tests pass without weakening the tests. Use when users ask for test-first workflows, RED/GREEN cycles, or behavior-gating tasks with automated tests.
Test-driven development with Kent Beck's canonical 5-step workflow: Test List, Write Test, Make Pass, Refactor, Repeat. Strict vertical-slice cycles with automatic project detection. Use when the user asks to "write tests first", "use TDD", "red-green-refactor", "test-driven development", "build a feature with TDD", "fix a bug with TDD", wants test-first development for any language or framework, or mentions "tracer bullet" or "vertical slice".
Test-driven development workflow enforcement for Python and React projects. Use when the user requests TDD, test-first development, or red-green-refactor methodology. Enforces strict cycle: write ONE failing test -> implement minimum code to pass -> refactor while green -> repeat. Applies to both backend (pytest) and frontend (Testing Library). Changes agent behavior to write tests before code. Does NOT provide testing patterns (use pytest-patterns or react-testing-patterns for how to write tests).
Test-Driven Development methodology and red-green-refactor workflow (formerly test-tdd). This skill should be used when practicing TDD, writing tests first, designing tests before implementation, or reviewing test-first approaches. Triggers on "write tests first", "test before code", "red green refactor", "test driven development". This skill does NOT cover Vitest framework specifics (use vitest skill) or API mocking with MSW (use msw skill).
Test-Driven Development workflow enforcement with RED-GREEN-REFACTOR cycle. Use when implementing features test-first or improving test coverage.
Run a safe, reviewable Aider CLI coding loop for local repositories: model setup, edit scope control, test-first prompting, commit hygiene, and fallback when agent edits drift. Use when the user wants pair-programming with Aider, not generic Git workflow or hosted PR operations.
Use this skill when > Test-Driven Development using red-green-refactor cycles with vertical slices. Tests verify behavior through public interfaces, not implementation details. Use when building new features or fixing bugs with a test-first discipline to produce well-designed, behavior-verified code.
Test-driven development using the RED-GREEN-refactor cycle. Suitable for users who want to build new features or fix bugs with TDD, mention "red-green-refactor", want to use integration testing, or ask about "test-first development".
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants test-first development, or requests TDD workflow.
Testing philosophy and practices. This skill should be used when writing tests, designing test strategies, or reviewing test code. Use proactively when discussing TDD, red-green-refactor, test doubles, mocks, stubs, fakes, RSpec, Jest, pytest, unit tests, integration tests, test coverage, or test-first development. (user)
Test-driven development methodology — red-green-refactor cycle, writing failing tests first, minimal implementation, and iterative refinement. Use when implementing features test-first, when the user asks for TDD, or when writing tests before code.
