Code quality standards. Defines complexity management, modular design, code smell detection, comment standards. Applied automatically when writing or reviewing code. Invoke directly to clean up comments in a file. Triggers on: 'clean up comments', 'comment cleanup', '/code-quality'.
Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.
Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.
Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions "red-green-refactor", or wants integration tests.
Self-review of code changes (branch diff, staged, or uncommitted). Use when: reviewing code before pushing, checking diff quality, self-reviewing a PR, creating a PR (always use --peer), reviewing uncommitted work. Triggers on: '/self-review', 'review my changes', 'review this branch', 'self-review', 'pre-push review', 'review uncommitted', 'review staged', 'create PR', 'open PR', 'submit PR'.
Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't. Read-only; it proposes motion with exact values, it does not implement it. Use when the user asks "what could be animated here?" or wants to "make this feel more alive". For fixing existing animations, use improve-animations or review-animations instead.
nix-darwin dotfiles configuration for macOS with Nix flakes and home-manager. Use when: adding/modifying programs, writing nix modules, editing host configs (workstation/homelab), debugging darwin-rebuild errors, managing homebrew packages via nix, or improving nix architecture.
