Checks

  • Ships scripts the agent can run. Read them before installing.
  • The name breaks the specification (lowercase letters, digits and single hyphens, up to 64 characters).

Pre-approved tools (allowed-tools): stitch*:*, Bash, Read, Write, web_fetch. The agent can use these without asking while the skill is active.

  8. stitch::code-to-designgoogle-labs-code/stitch-skills

    Convert frontend code (Vite, React, Angular, Vue, etc.) to a Stitch Design by chaining static HTML extraction, design system extraction, and file upload. **ALWAYS** use this skill when the user's intent is to move existing web apps or React/Angular/Vue components into Stitch (e.g., requests to "save", "migrate", or "upload"). You must use this skill even for simple "save" operations, as it is the only way to ensure the design system is extracted and assets are properly linked.
