Applies TDD workflow to development. Use when writing tests before code, implementing features test-first, fixing bugs via failing test, or refactoring with test coverage. Detects AI anti-patterns.
This skill should be used when fixing bugs, implementing features, debugging issues, or making code changes. Ensures understanding of code flow before implementation by: (1) Tracing execution path with specific file:line references, (2) Creating lightweight text diagrams showing class.method() flows, (3) Verifying understanding with user. Prevents wasted effort from assumptions or guessing. Triggers when users request: bug fixes, feature implementations, refactoring, TDD cycles, debugging, code analysis.
Autonomous build-phase orchestrator. Manages slice queue, TDD pair dispatch, full-team code review, mutation testing, CI integration, and auto-merge with quality gates. Replaces manual coordinator overhead during build phase. Activate when running factory mode with ensemble-team.
Domain modeling principles: parse-don't-validate, make invalid states unrepresentable, primitive obsession detection, semantic types, and domain veto authority. Activate when designing types, reviewing code for domain integrity, or when domain review is needed in a TDD cycle.
アイデアをPlans.mdに落とし込む。夢を計画に変える魔法使い。Use when user mentions '/plan-with-agent', create a plan, organize tasks, feature planning, or TDD planning. Do NOT load for: implementation, reviews, or setup.
Deprecated alias for tdd skill
Create a new feature/bug track with spec and implementation plan. Interactive interview generates requirements spec, then phased TDD plan. Use when starting work on a new feature, bug fix, or chore.
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.
TDD and testing skills for iOS/macOS apps. Covers characterization tests, TDD workflows, test contracts, snapshot tests, and test infrastructure. Use for test-driven development, adding tests to existing code, or building test infrastructure.
Testing principles, strategies, and patterns. Covers the testing pyramid, test design, TDD, test doubles, and common testing antipatterns. Stack-agnostic.
Creates structured Request for Comments (RFC) documents for proposing and deciding on significant changes. Use when the user says "write an RFC", "create a proposal", "I need to propose a change", "draft an RFC", "document a decision", or needs stakeholder alignment before making a major technical or process decision. Do NOT use for TDDs/implementation docs (use technical-design-doc-creator instead), README files, or general documentation.
Agent development workflow and discipline skills. Use when developing features, debugging issues, managing code branches, writing plans, or ensuring code quality through TDD and systematic processes. Triggers on any software development task that benefits from structured workflows.
