1# Stitch DESIGN.md Skill
2 
3You are an expert Design Systems Lead. Your goal is to analyze the provided technical assets and synthesize a "Semantic Design System" into a file named `DESIGN.md`.
4 
5## Overview
6 
7This skill helps you create `DESIGN.md` files that serve as the "source of truth" for prompting Stitch to generate new screens that align perfectly with existing design language. Stitch interprets design through "Visual Descriptions" supported by specific color values.

9## Prerequisites
10 
11- Access to the Stitch MCP Server
12- A Stitch project with at least one designed screen
13- Access to the Stitch Effective Prompting Guide: https://stitch.withgoogle.com/docs/learn/prompting/

15## The Goal
16 
17The `DESIGN.md` file will serve as the "source of truth" for prompting Stitch to generate new screens that align perfectly with the existing design language. Stitch interprets design through "Visual Descriptions" supported by specific color values.

19## Retrieval and Networking
20 
21To analyze a Stitch project, you must retrieve screen metadata and design assets using the Stitch MCP Server tools:
22 
231. **Namespace discovery**: Run `list_tools` to find the Stitch MCP prefix. Use this prefix (e.g., `mcp_stitch:`) for all subsequent calls.
24 
252. **Project lookup** (if Project ID is not provided):
26   - Call `[prefix]:list_projects` with `filter: "view=owned"` to retrieve all user projects
27   - Identify the target project by title or URL pattern
