Stitch Skills
Official library by Google Labs / Stitch that packages Agent Skills (Anthropic .md format) to read and write DESIGN.md. Includes a `design-md` skill (file CRUD), a `tokens` skill (export to Tailwind/DTCG), and a `validate` skill (WCAG + references check). Compatible with Claude Code, Cursor, Antigravity, Gemini CLI.
Strengths
- Official Google Labs, aligned with DESIGN.md spec, synchronous updates
- Follows the open Anthropic Agent Skills standard, cross-runtime usable (Claude Code / Cursor / Antigravity / Gemini CLI)
- `design-md` + `tokens` + `validate` skills cover the full DESIGN.md lifecycle without human intervention
Limitations
- Coupled to Stitch (the Google Labs tool), some skills only work with the Stitch MCP server
- Still young (March 2026), skills evolving rapidly, breaking changes possible
Best for
- Design system managers who want to integrate DESIGN.md into team workflow without coding commands themselves
- Multi-IDE teams (Claude Code + Cursor + Antigravity) wanting consistent DESIGN.md behavior
- Devs exporting tokens to Tailwind/DTCG who want a validated command rather than a homegrown script
