Android Test-Driven Development standards. Enforces Red-Green-Refactor cycle, test pyramid (70/20/10), layer-specific testing strategies, and CI integration. Use when building or reviewing Android apps with TDD methodology.
Use when ready to implement designed features - breaks design into TDD tasks (Red-Green-Refactor), tracks progress with checkboxes in tasks.md, enforces strict testing discipline. Activates when user says "implement this", "let's code", "start execution", mentions "tasks", "TDD", or uses /dev-workflow:spec commands (tasks, execute).
Apply SPARC methodology (Specification, Pseudocode, Architecture, Refinement, Completion) for systematic development. Use for feature development, TDD workflows, and structured problem-solving.
Use when writing tests, adding coverage, implementing business logic, or building features with TDD. Enforces output-based testing of pure functions only - never test imperative shell directly.
iOS crash-hunter skill that finds and fixes gnarly concurrency, memory, and I/O bugs using TDD. Every rule shows dangerous code, a failing test that proves the crash, and the fix that makes it pass. Complements ios-testing, swift-optimise, and other ios-*/swift-* skills. Triggers on tasks involving data races, retain cycles, deadlocks, async/await pitfalls, file corruption, thread safety, or crash debugging in Swift/iOS apps.
Use when writing new functions, adding features, fixing bugs, or refactoring by applying TDD principles - write failing tests before implementation code, make them pass, then refactor.
TypeScript/JavaScript Test-Driven Development with Vitest, strict red-green-refactor methodology, React component testing, and comprehensive coverage patterns. Use when implementing TypeScript features with TDD, writing Vitest tests, testing React components, developing with test-first approach, or when user mentions 'TypeScript TDD', 'Vitest', 'React testing', 'JavaScript TDD', 'red-green-refactor', 'TypeScript unit tests', or 'test-driven TypeScript'.
Execute a PRP with validation loop, TDD workflow, and quality gates
Move testing activities earlier in the development lifecycle to catch defects when they're cheapest to fix. Use when implementing TDD, CI/CD, or early quality practices.
Build phase of RDD. Turns behavior scenarios into executable BDD specs, then implements via TDD (red/green/refactor). Enforces structure-vs-behavior separation, composable tests, and small reversible steps. Use after /rdd-decide when scenarios and domain model are approved.
Guide to effective Claude Code skill authoring using TDD methodology and persuasion principles. Use when creating new skills, improving compliance, or validating quality before deployment. Do not use for evaluating existing skills (use skills-eval) or analyzing architecture (use modular-skills). Follow the Iron Law: write a failing test before writing any skill.
Full feature pipeline — pre-flight checks, TDD cycle, scope guard, quality commit. Combines pre-flight + tdd + scope-check + quality-commit into one flow. Use when implementing a feature, adding an endpoint, or building any non-trivial code change.
