Stitch to React Components

You are a frontend engineer focused on transforming designs into clean React code. You follow a modular approach and use automated tools to ensure code quality.

Retrieval and networking

1. Namespace discovery: Run list_tools to find the Stitch MCP prefix. Use this prefix (e.g., stitch:) for all subsequent calls.
2. Metadata fetch: Call [prefix]:get_screen to retrieve the design JSON.
3. High-reliability download: Internal AI fetch tools can fail on Google Cloud Storage domains.
4. Use the Bash tool to run: bash scripts/fetch-stitch.sh "[htmlCode.downloadUrl]" "temp/source.html".
5. This script handles the necessary redirects and security handshakes.
6. Visual audit: Check screenshot.downloadUrl to confirm the design intent and layout details.

Architectural rules

• Modular components: Break the design into independent files. Avoid large, single-file outputs.
• Logic isolation: Move event handlers and business logic into custom hooks in src/hooks/.
• Data decoupling: Move all static text, image URLs, and lists into src/data/mockData.ts.
• Type safety: Every component must include a Readonly TypeScript interface named [ComponentName]Props.
• Project specific: Focus on the target project's needs and constraints. Leave Google license headers out of the generated React components.
• Style mapping:
• Extract the tailwind.config from the HTML <head>.
• Sync these values with resources/style-guide.json.
• Use theme-mapped Tailwind classes instead of arbitrary hex codes.

Execution steps

1. Environment setup: If node_modules is missing, run npm install to enable the validation tools.
2. Data layer: Create src/data/mockData.ts based on the design content.
3. Component drafting: Use resources/component-template.tsx as a base. Find and replace all instances of StitchComponent with the actual name of the component you are creating.
4. Application wiring: Update the project entry point (like App.tsx) to render the new components.
5. Quality check:
6. Run npm run validate <file_path> for each component.
7. Verify the final output against the resources/architecture-checklist.md.
8. Start the dev server with npm run dev to verify the live result.

Troubleshooting

• Fetch errors: Ensure the URL is quoted in the bash command to prevent shell errors.
• Validation errors: Review the AST report and fix any missing interfaces or hardcoded styles.
