Stitch Design Skills is a collection of Agent Skills and plugins for Google Stitch, a design tool accessed through the Stitch MCP server. It is for coding agents such as Codex, Antigravity, Gemini CLI, Claude Code, Cursor, and OpenCode, with catalogue entries covering Stitch design, build, and utility workflows.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00140 | $0.03263 |
| Opus 5.5 | $0.00056 | $0.01305 |
| Sonnet 5.5 | $0.00028 | $0.00653 |
| Haiku 4.5 | $0.00014 | $0.00326 |
Grade A, and why
stitch::extract-design-md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 366 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Extract Design System from Frontend Code
Analyze frontend source code to extract a comprehensive design system document (DESIGN.md) that captures the project's visual language — colors, typography, spacing, component patterns, and layout principles — directly from the source files, without needing to build or render the application.
Why This Exists
The design-md skill works from rendered HTML. But often you have a codebase
and want to understand its design system before you can even run the app —
maybe dependencies are missing, the build is broken, or you just want a quick
audit. This skill reads the source files themselves: stylesheets, component
files, theme configs, and Tailwind setups. It's faster and works anywhere.
When to Use
- User has a frontend codebase and wants to extract or document its design system
- User wants to migrate a project's visual identity into Stitch
- User asks to "audit the styling" or "understand the design language" of a repo
- User wants to create a DESIGN.md from existing source code
- The app can't be built/rendered but the source is available
- User wants to unify or reconcile inconsistent styles across a codebase
Prerequisites
- Access to the frontend project's source directory
- No build or runtime dependencies needed — this skill reads source files only
Workflow
Phase 1: Project Discovery
Start by understanding what you're working with. This determines which extraction patterns to use.
1. Detect the Framework and Stack
Scan the project root for telltale files:
| Signal File | Framework / Tool |
|---|---|
package.json with react |
React / Next.js |
package.json with vue |
Vue / Nuxt |
package.json with svelte |
Svelte / SvelteKit |
package.json with @angular/core |
Angular |
tailwind.config.js/ts |
Tailwind CSS |
postcss.config.js |
PostCSS pipeline |
styled-components or @emotion in deps |
CSS-in-JS |
.css / .scss / .less files only |
Plain CSS / SASS |
theme.js / theme.ts / tokens.js |
Design token files |
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

stitch::extract-design-md is a skill published in the GitHub repository google-labs-code/stitch-skills (8,690 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 140 tokens to every session and 3,263 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
