design-review
Use when refining an architecture or design document based on new learnings, before a rewrite. Use when you have an existing doc and related docs to cross-check against. Use when you need systematic section-by-section validation of decisions.
What this skill does
# Design Review ## Overview **Design review separates validation from rewriting.** Go section-by-section through a design doc, cross-check against new learnings, record changes with rationale, then rewrite in a fresh session. **Core principle:** Changes document first, rewrite second. Never edit inline. ## When to Use - Refining v1 → v2 of an architecture doc - Incorporating implementation learnings into design - Cross-checking design against related docs - Validating past decisions after new context **Don't use:** Writing from scratch (use brainstorming), minor edits, obvious changes. ## Process ### 1. Create Changes Document ```markdown # [Design Name] v[N+1]: Changes > After full review, create fresh v[N+1] incorporating all changes. ## Changes ``` ### 2. Section-by-Section Review For each section: 1. Summarize current state 2. Cross-check against new learnings 3. Ask clarifying questions 4. Record change or confirm unchanged **Questions to ask:** - Does this still hold given what we now know? - Anything missing? Contradicts other sections? - Right level of detail for this doc? ### 3. Change Format ```markdown ### [N]. [Short Description] **Section:** [Section name] **Change:** [What's changing] **Rationale:** [Why] --- ``` ### 4. Structural Principles | Principle | Meaning | |-----------|---------| | Main body vs Appendix | "What we're doing" vs "paths we rejected" | | No mixed content | Remove sections with undiscussed details mixed in | | Feature sections own data | Each feature owns its endpoints/models, no central lists | | No timelines | Architecture = what, not when | ### 5. Fresh Session Rewrite **Do NOT rewrite in same session.** Start fresh with: - Original design doc - Changes document - Related docs (reference) ## Red Flags - "I'll just fix this inline" → Use changes document - "This section looks fine" → Confirm aloud or mark unchanged - "I'll remember why" → Write rationale now - "Let me rewrite now" → Fresh session required - "Auto-generated but reasonable" → Validate or remove ## Common Mistakes | Mistake | Fix | |---------|-----| | Inline editing | Always use changes document | | Skipping sections | Review every section | | No rationale | Always include "why" | | Same-session rewrite | Fresh session for rewrite | | Keeping auto-generated details | Validate each or remove |

contribute
IncludedLocal-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".
architectural-analysis
IncludedUser-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).
mcp
IncludedModel Context Protocol (MCP) server development and tool management. Languages: Python, TypeScript. Capabilities: build MCP servers, integrate external APIs, discover/execute MCP tools, manage multi-server configs, design agent-centric tools. Actions: create, build, integrate, discover, execute, configure MCP servers/tools. Keywords: MCP, Model Context Protocol, MCP server, MCP tool, stdio transport, SSE transport, tool discovery, resource provider, prompt template, external API integration, Gemini CLI MCP, Claude MCP, agent tools, tool execution, server config. Use when: building MCP servers, integrating external APIs as MCP tools, discovering available MCP tools, executing MCP capabilities, configuring multi-server setups, designing tools for AI agents.
react-native-skia
IncludedDesign, build, debug, and optimise high-polish animated graphics in React Native or Expo using @shopify/react-native-skia, Reanimated, and Gesture Handler. Use when the user wants canvas-driven UI, shaders, paths, rich text, image filters, sprite fields, Skottie, video frames, snapshots, web CanvasKit setup, or performance tuning for custom motion-heavy elements such as loaders, hero art, cards, charts, progress indicators, particle systems, or gesture-driven surfaces. Also use when the user asks for fluid, glow, glass, blob, parallax, 60fps/120fps, or GPU-friendly animated effects in React Native, even if they do not explicitly say "Skia". Do not use for ordinary form/layout work with standard views.
plaid
IncludedProduct Led AI Development — guides founders from idea to launched product. Six capabilities: Idea (discover a product idea), Validate (pressure-test the idea against fatal flaws, problem reality, competition, and 2-week MVP feasibility), Plan (vision intake + document generation), Design (translate image references into a design.md spec), Launch (go-to-market strategy), and Build (roadmap execution). Use when someone says "PLAID", "plaid idea", "help me find an idea", "product idea", "idea from my business", "idea from my expertise", "plaid validate", "validate my idea", "pressure-test", "is this idea good", "find fatal flaws", "validate the problem", "plan a product", "define my vision", "generate a PRD", "product strategy", "plaid design", "design from image", "translate image to design", "create design.md", "extract design tokens", "plaid launch", "go-to-market", "launch plan", "GTM strategy", "launch playbook", "plaid build", "build the app", "start building", or "execute the roadmap".
nextjs-framer-motion-animations
IncludedAdds production-safe Motion for React or Framer Motion animations to Next.js apps, including reveal, hover and tap micro-interactions, whileInView, stagger, AnimatePresence, layout and layoutId transitions, reorder, scroll-linked UI, and lightweight route-content transitions. Use when the user asks to add, refactor, or debug Motion or Framer Motion in App Router or Pages Router codebases, especially around server/client boundaries, reduced motion, LazyMotion, bundle size, hydration, or route transitions. Avoid for GSAP-style timelines, WebGL or 3D scenes, heavy scroll storytelling, or CSS-only effects unless Motion is explicitly requested.
