Use when implementing any feature or bugfix, before writing implementation code
Drives development with tests. Use when implementing any logic, fixing any bug, or changing any behavior. Use when you need to prove that code works, when a bug report arrives, or when you're about to modify existing functionality.
TDD: enforce RED-GREEN-REFACTOR, tests before code.
RED-GREEN-REFACTOR cycle with strict phase gates. Write failing test first, implement minimum code to pass, then refactor while keeping tests green. Use when implementing new features, fixing bugs with test-first approach, improving test coverage, or when user mentions TDD. Use for "TDD", "test first", "red green refactor", "write tests", or "implement with tests". Do NOT use for debugging existing failures (use systematic-debugging) or for refactoring without new tests (use systematic-refactoring).
Test-Driven Development enforces the RED-GREEN-REFACTOR discipline on every code change an agent produces.
Used when implementing any feature or fixing bugs, before writing the implementation code
Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first
Red-green-refactor development methodology requiring verified test coverage. Use for feature implementation, bugfixes, refactoring, or any behavior changes where tests must prove correctness.
TDD workflow guide. Use PROACTIVELY when writing new features or fixing bugs. Enforces Red-Green-Refactor cycle and prevents testing anti-patterns.
Write tests before implementation code. Use when starting new features or fixing bugs. Covers Red-Green-Refactor cycle and TDD best practices.
Enforce Test-Driven Development (TDD) workflow for all code changes. Apply PROACTIVELY by default using Red-Green-Refactor cycles for features, bug fixes, and refactoring.
Used when implementing any feature or bug fix before writing production code
