Use when writing any new code, adding features, or fixing bugs that require code changes. Enforces strict RED-GREEN-REFACTOR cycle with no production code without a failing test first. Triggers: new feature implementation, bug fix, refactoring existing code, adding behavior to existing modules.
Test-Driven Development workflow principles. RED-GREEN-REFACTOR cycle.
Guides strict Test-Driven Development (TDD) using the Red-Green-Refactor cycle. Ensures no production code is written without a prior failing test. Use this skill when implementing new features, fixing bugs, or refactoring code to ensure high test coverage and design quality. Triggers on phrases like 'TDD', 'write tests first', 'test-driven', 'red-green-refactor', 'watch it fail', 'test first', or 'behavior driven'.
Use red-green-refactor to implement features and bug fixes with tests first. Only use if requested explicitely, for general tdd use mattpocock/skills/tdd
Test-driven development with strict RED-GREEN-REFACTOR enforcement. Enforces: write failing test first, minimal implementation, then refactor. Use when adding new features or fixing bugs.
Use this skill when writing Go tests with stretchr/testify, implementing TDD workflows, creating mocks, or organizing test suites. Covers assert vs require patterns, interface mocking, table-driven tests, and the red-green-refactor cycle.
Master TDD orchestrator specializing in red-green-refactor discipline, multi-agent workflow coordination, and comprehensive test-driven development practices. Enforces TDD best practices across teams with AI-assisted testing and modern frameworks. Use PROACTIVELY for TDD implementation and governance.
Write tests before implementation code. Use when starting new features or fixing bugs. Covers Red-Green-Refactor cycle and TDD best practices.
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).
TDD-based code simplification that preserves behavior through tests. Use Red-Green-Refactor cycles to simplify code one test-verified change at a time. **DISTINCT FROM**: General code review or AI rewriting—this skill requires existing tests and only proceeds when tests confirm behavior is preserved. **PROACTIVE**: Auto-invoke when test-covered code has complexity (functions >50 lines, high cyclomatic complexity, duplication) and user wants to simplify it safely. Trigger phrases: 'clean up code', 'make code simpler', 'reduce complexity', 'refactoring help'. **NOT FOR**: Adding features or fixing bugs—use /tdd skill instead.
Use when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes
Jest testing patterns, factory functions, mocking strategies, and TDD workflow. Use when writing unit tests, creating test factories, or following TDD red-green-refactor cycle.
