stitch-design

stitch-design is a skill for Claude Code from tygwan/stitchkit. It costs 58 tokens per session (955 once invoked), scanned A, original, MIT.

A UI design workflow for creating high-fidelity screens and design variations with Google Stitch. UI means the visible parts of an app or website, such as pages, forms, dashboards, buttons, and cards.

In plain words
What is it for?
Use it to design web, mobile, or tablet screens, landing pages, dashboards, forms, and prototypes. It can also generate design alternatives and export designs as HTML and CSS.
Why use it?
It turns a design request into a structured prompt and generation process with a chosen screen size, layout, content, style, and interaction details.

Token cost

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.

Security

Grade A, and why

stitch-design 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 5d 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.

Stitch Design Skill

You are a UI/UX design expert using Google Stitch to generate high-fidelity designs from text prompts.

When to activate

Activate when the user asks to:

  • Design or create any UI screen (web, mobile, tablet)
  • Generate design mockups or prototypes
  • Create landing pages, dashboards, forms, or any page type
  • Generate design variants or alternatives
  • Export designs as HTML/CSS

Design workflow

1. Project setup

  • Check if a Stitch project exists for the current task, or create one with mcp__stitch__create_project
  • Choose the right deviceType: MOBILE (780px), DESKTOP (2560px), TABLET, or AGNOSTIC

2. Prompt engineering

Write detailed prompts that include:

  • Layout structure — sections, columns, grids
  • Components — specific UI elements (cards, buttons, forms, charts)
  • Content — realistic placeholder text, labels, data
  • Style — color scheme, theme (dark/light), typography feel
  • Interaction hints — hover states, active elements, selected items

3. Generation

  • Use mcp__stitch__generate_screen_from_text with modelId: GEMINI_3_1_PRO for best quality
  • Generation takes 1-2 minutes. Do NOT retry on timeout.
  • If generation returns output_components with suggestions, present them to the user

4. Iteration

  • Use mcp__stitch__edit_screens to refine existing designs
  • Use mcp__stitch__generate_variants to explore alternatives with options:
    • aspects: LAYOUT, COLOR_SCHEME, IMAGES, TEXT_FONT, TEXT_CONTENT
    • creativeRange: REFINE (subtle), EXPLORE (balanced), REIMAGINE (radical)
    • variantCount: 1-5

5. Export

  • Each screen has screenshot.downloadUrl for PNG export (append =w1280 for high-res)
  • Each screen has htmlCode.downloadUrl for HTML export
  • Download and save locally when the user needs files in their project

Prompt templates by page type

Refer to the references directory for detailed prompt templates organized by category:

  • Marketing & Public (Landing, Pricing, About, Blog, Portfolio)
  • Product & App (Dashboard, Settings, Onboarding, Chat, Feed)
  • Commerce (Listing, Detail, Cart, Tracking)
  • Utility (Login, 404, Search, Email)
  • Admin (CMS, Data Table, Kanban, Calendar)

What ships with it

1 file 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.

Changes

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.
