stitch-to-react
Converts Google Stitch exports into React components with design DNA integration. Use when user references design-intent/google-stitch exports, mentions "convert Stitch output", "Stitch to React", or processes Stitch code directories containing HTML + PNG pairs.
What this skill does
# Stitch to React
Convert Google Stitch exports (Tailwind HTML + PNG) into React components with full design system integration.
**Core Philosophy**: Decompose Stitch screens into composable React components while respecting established patterns.
## Quick Start
### 0. Verify Exports Exist (Mandatory)
Before any conversion, verify Stitch exports are available:
```bash
# Check for HTML/PNG pairs in the expected location
Glob: design-intent/google-stitch/{feature}/exports/*.html
Glob: design-intent/google-stitch/{feature}/exports/*.png
```
**If exports found:** Proceed to Step 1.
**If exports NOT found:**
1. Check if user specified wrong path - ask for correct location
2. Suggest running `/stitch-generate` first to create exports
3. Fall back to design docs: Check `/design-intent/patterns/` for established patterns or project directories for screenshots
4. If no design assets exist, inform user and offer to help create them
**Report findings:**
```
Export Check: [PASSED/MISSING]
- HTML files: [count] found
- PNG files: [count] found
- Location: design-intent/google-stitch/{feature}/exports/
```
### 1. Load Project Context (Mandatory)
Before any conversion:
1. Read `/design-intent/memory/constitution.md` for project principles
2. Read `/design-intent/patterns/` for established patterns
3. Detect project design system (Fluent UI, Material UI, custom, etc.)
4. Report: "Existing patterns to consider: [list]"
### 2. Scan Stitch Exports
Stitch exports are located at:
```
design-intent/google-stitch/{feature}/exports/
├── 01-layout-{name}.html # Tailwind CSS + HTML
├── 01-layout-{name}.png # Visual reference
├── 02-component-{name}.html
├── 02-component-{name}.png
└── ...
```
From each HTML file, extract:
- Inline `tailwind.config` (colors, fonts, spacing)
- Custom `<style>` blocks (animations, keyframes)
- DOM structure for component hierarchy
- Material Symbols icons usage
### 3. Map to Project Design System
For each Stitch element:
1. **Check existing patterns** - Can we reuse established components?
2. **Map Tailwind tokens** - Convert to project design tokens
3. **Decompose into composable parts** - Break screens into smaller, reusable components
4. **Flag conflicts** - Note when Stitch output differs from patterns
### 4. Generate React Components
Output structure:
```
src/components/{feature}/
├── {ComponentName}.tsx # Main component
├── {SubComponent}.tsx # Decomposed smaller components
├── tokens.ts # Design tokens from Stitch config
├── types.ts # TypeScript interfaces
└── index.ts # Re-exports
```
## Component Selection Priority
Per constitution principles:
1. **Existing project components** from `/design-intent/patterns/`
2. **Framework components** (Fluent UI, project design system)
3. **Custom components** (document with header comment)
## Conflict Resolution
When Stitch output conflicts with patterns:
```
## Design Conflict Detected
**Element**: Button border-radius
**Stitch Output**: 4px
**Existing Pattern**: 8px (button-styling.md)
### Options
1. Follow Stitch output - Use 4px
2. Use existing pattern - Use 8px
3. Update pattern - Make 4px the new standard
Which approach?
```
## Custom Component Documentation
```tsx
/**
* CUSTOM COMPONENT: ComponentName
* Source: Stitch screen name
* Base: @fluentui/react-components/ComponentType (if applicable)
* Reason: Why custom implementation was needed
* Created: YYYY-MM-DD
*
* Original Reference: design-intent/google-stitch/{feature}/exports/{screen}.png
*/
```

- **Common issues**: See [TROUBLESHOOTING.md](TROUBLESHOOTING.md)
## Invocation
Triggered by:
- User references `design-intent/google-stitch/` exports
- "Convert Stitch output to React"
- "Stitch to React" requests
- Processing directories with HTML + PNG pairs from Stitch

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.
