Google Labs released stitch-skills, an official agent skills library packaging Stitch into plugins for Claude Code, Cursor, Codex, Gemini CLI, and Antigravity. The library follows the Agent Skills open standard.
Three plugin sets: Design (code-to-Stitch, UI generation, design systems), Build (React/React Native with shadcn/ui), and Utilities (design analysis, multi-page site generation via stitch-loop self-driving loop).
Everything runs through the Stitch MCP server configured once in the agent. Typical flow: point Claude Code at a repo, generate matching screens in Stitch, pull back production components — design-to-code without leaving the terminal.
