Full-stack-skills stitch-design-md
Analyze Stitch projects and synthesize a semantic design system into DESIGN.md. Use when the user wants to extract a style guide, create visual consistency across Stitch screens, or document design tokens (colors, typography, spacing) from existing Stitch designs. Retrieves screens via Stitch MCP and outputs a markdown design system file.

Constraint: Only use this skill when the user explicitly mentions "Stitch" or when preparing design system docs for Stitch generation.
You are an expert Design Systems Lead. Your goal is to analyze Stitch project assets and synthesize a Semantic Design System into a file named
DESIGN.md.
Overview
DESIGN.md is the source of truth for prompting Stitch to generate new screens that match existing design language. Stitch interprets design through visual descriptions and specific color values. This skill uses Stitch MCP to fetch project and screen data; you can call stitch-mcp-list-projects, stitch-mcp-list-screens, stitch-mcp-get-screen, stitch-mcp-get-project (or the underlying MCP tools with your client’s prefix) to retrieve metadata and download HTML/screenshots.
Prerequisites
- Stitch MCP Server configured (see https://stitch.withgoogle.com/docs/mcp/guide/)
- A Stitch project with at least one designed screen
- Stitch Effective Prompting Guide: https://stitch.withgoogle.com/docs/learn/prompting/
Retrieval and Networking
Use Stitch MCP (or skills
stitch-mcp-list-projects, stitch-mcp-get-project, stitch-mcp-list-screens, stitch-mcp-get-screen) in this order.
When the user provides a Stitch design URL
If the user pastes a Stitch design page link (e.g.
https://stitch.withgoogle.com/projects/3492931393329678076?node-id=375b1aadc9cb45209bee8ad4f69af450):
- Parse the URL:
- projectId = segment after
and before/projects/
(e.g.?
)3492931393329678076 - screenId = query parameter
(e.g.node-id
)375b1aadc9cb45209bee8ad4f69af450
- projectId = segment after
- Fetch the screen: Call
with the parsed[prefix]:get_screen
andprojectId
(no need to call list_projects or list_screens).screenId - Continue with step 5 below (asset download) and then Analysis & Synthesis.
When project/screen IDs are unknown
-
Namespace discovery: Run
to find the Stitch MCP prefix (e.g.list_tools
). Use that prefix for all calls.mcp_stitch__stitch: -
Project lookup (if Project ID unknown):
- Call
with[prefix]:list_projectsfilter: "view=owned" - Identify the target project by title; extract Project ID from
(e.g.name
)projects/13534454087919359824
- Call
-
Screen lookup (if Screen ID unknown):
- Call
with[prefix]:list_screens
(numeric ID only)projectId - Identify target screen by title; extract Screen ID from
name
- Call
-
Metadata fetch:
- Call
with[prefix]:get_screen
andprojectId
(numeric IDs)screenId - Use returned
,screenshot.downloadUrl
,htmlCode.downloadUrl
,width
,height
, and projectdeviceTypedesignTheme
- Call
-
Asset download (also after URL-based get_screen):
- Use
or equivalent to download HTML fromweb_fetch
and optionally screenshot fromhtmlCode.downloadUrlscreenshot.downloadUrl - Parse HTML for Tailwind classes, custom CSS, and component patterns
- Use
-
Project metadata:
- Call
with project[prefix]:get_project
(full pathname
) to getprojects/{id}
, fonts, roundness, custom colors, layout principlesdesignTheme
- Call
Analysis & Synthesis
1. Extract Project Identity
- Project title and Project ID (from JSON
)name
2. Define the Atmosphere
From screenshot and HTML: mood, density, aesthetic (e.g. "Airy," "Minimalist," "Utilitarian").
3. Map the Color Palette
For each key color:
- Descriptive name (e.g. "Deep Muted Teal-Navy")
- Hex in parentheses (e.g. "#294056")
- Functional role (e.g. "Used for primary actions")
4. Translate Geometry & Shape
→ "Pill-shaped"rounded-full
→ "Subtly rounded corners"rounded-lg
→ "Sharp, squared-off edges"rounded-none
5. Describe Depth & Elevation
Shadows and layers: "Flat," "Whisper-soft diffused shadows," "Heavy drop shadows," etc.
Output Guidelines
- Language: Descriptive design terminology and natural language only
- Format: Markdown following the structure below
- Precision: Exact hex codes plus descriptive names
- Context: Explain the "why" behind design decisions
Output Format (DESIGN.md Structure)
# Design System: [Project Title] **Project ID:** [Insert Project ID Here] ## 1. Visual Theme & Atmosphere (Description of mood, density, and aesthetic philosophy.) ## 2. Color Palette & Roles (Descriptive Name + Hex + Functional Role for each color.) ## 3. Typography Rules (Font family, weights for headers vs body, letter-spacing.) ## 4. Component Stylings * **Buttons:** Shape, color, behavior. * **Cards/Containers:** Corner roundness, background, shadow. * **Inputs/Forms:** Stroke style, background. ## 5. Layout Principles (Whitespace, margins, grid alignment.) ## 6. Design System Notes for Stitch Generation (Language and color references to copy into Stitch prompts; see examples/DESIGN.md.)
Integration with This Repo
- First time: Generate
with this skill from an existing Stitch screen.DESIGN.md - Multi-page: Use
to inject DESIGN.md Section 6 into prompts; usestitch-ui-prompt-architect
for baton-based multi-page builds.stitch-loop - Framework alignment: For framework-specific constraints (Layui, Element Plus, uView, etc.), combine DESIGN.md with the corresponding
contract in the prompt.stitch-ui-design-spec-*
Best Practices
- Be descriptive: e.g. "Ocean-deep Cerulean (#0077B6)" not "blue"
- Be functional: Explain what each element is used for
- Be consistent: Same terminology throughout
- Be precise: Exact values in parentheses after natural language
Common Pitfalls
- ❌ Technical jargon without translation ("rounded-xl" → "generously rounded corners")
- ❌ Omitting color codes or only descriptive names
- ❌ Skipping functional roles of design elements
- ❌ Vague atmosphere descriptions
- ❌ Ignoring shadows or spacing patterns
