Stitch Design Skills

A collection of agent skills and plugins for Google Stitch, following the Agent Skills open standard. Compatible with coding agents such as Codex, Antigravity, Gemini CLI, Claude Code, and Cursor.

Quick Start

1. Install Plugins (Recommended)

The fastest way to set up the full Stitch plugin suite globally.

Codex

In Codex, add this repository as a plugin marketplace:

Field	Value
Source	https://github.com/google-labs-code/stitch-skills
Git ref	main
Sparse paths	Leave empty, or use the paths below for a smaller checkout

Optional sparse paths:

.agents/plugins
plugins/stitch-design
plugins/stitch-build
plugins/stitch-utilities

Do not use plugins/codex; that path does not exist in this repository.

The equivalent Codex CLI command is:

codex plugin marketplace add google-labs-code/stitch-skills --ref main \
  --sparse .agents/plugins \
  --sparse plugins/stitch-design \
  --sparse plugins/stitch-build \
  --sparse plugins/stitch-utilities

After adding the marketplace, install the plugins you need from the Stitch Skills marketplace:

• stitch-design
• stitch-build
• stitch-utilities

Claude Code

npx plugins add google-labs-code/stitch-skills --scope project --target claude-code

2. Install Skills Selectively

Choose only the specific skills you need.

npx skills add google-labs-code/stitch-skills

You can run the following commands to see the help documentation for plugins and skills:

npx plugins --help

npx skills --help

Prerequisites

These skills require the Stitch MCP server to be configured and running in your agent's environment. Make sure you have followed the Stitch MCP Setup Instructions to register the server and set up appropriate environment variables and credentials.

Adding New Skills

All new skills need to follow the file structure above to implement the Agent Skills open standard.

Great candidates for new skills

• Validation: Skills that convert Stitch HTML to other UI frameworks and validate the syntax.
• Decoupling Data: Skills that convert static design content into external mock data files.
• Generate Designs: Skills that generate new design screens in Stitch from a given set of data.
