Stitch Design System
When to Use
Load this skill when the user request matches the frontmatter description for Stitch Design System.
Extract Stitch designs into semantic DESIGN.md files that serve as authoritative references for generating new screens with consistent visual language.
NEVER
- Never use technical CSS values in DESIGN.md without semantic translation —
rounded-xl means nothing to Stitch; write "generously rounded corners" so visual intent is clear.
- Never omit hex codes — color names are ambiguous;
Ocean-deep Cerulean (#0077B6) enables exact replication, "blue" does not.
- Never omit functional roles — "blue button" is unusable; "Deep Ocean Blue (#0077B6) for primary call-to-action" is actionable.
- Never use unspecific atmosphere words like "modern", "nice", or "clean" — every design is these things; write sensory descriptions like "airy and minimal with generous whitespace" or "dense, information-rich, utilitarian".
- Never name colors by appearance alone — name them by purpose: primary, secondary, destructive, surface, muted.
- Never skip shadows and spacing — these define perceived elevation and hierarchy, which Stitch uses to understand visual weight.
What Makes a Good DESIGN.md
Stitch generates new screens from natural language descriptions. DESIGN.md is the bridge between technical assets (HTML/CSS) and Stitch's language model. The quality of translation directly determines consistency of generated screens.
Good translation:
- Technical:
box-shadow: 0 1px 3px rgba(0,0,0,0.08)
- Semantic: "Whisper-soft diffused shadows, barely perceptible, creating gentle elevation"
Poor translation:
- Technical:
box-shadow: 0 1px 3px rgba(0,0,0,0.08)
- Semantic: "Light shadow" (too vague for Stitch to reproduce)
Retrieval Workflow
- Call
[prefix]:list_projects (filter: view=owned) — extract numeric Project ID from name field
- Call
[prefix]:list_screens with projectId — identify target screen by title
- Call
[prefix]:get_screen with projectId + screenId — get screenshot.downloadUrl, htmlCode.downloadUrl, designTheme
- Call
[prefix]:get_project with full name path (projects/{id}) — get designTheme object (colors, fonts, roundness)
web_fetch the htmlCode.downloadUrl — parse Tailwind classes, custom CSS, component patterns- Optionally
web_fetch screenshot for visual verification of atmosphere
Semantic Translation Guide
Colors
For each color: Descriptive name conveying character + hex code + functional role.
Deep Muted Teal-Navy (#294056) — primary surface, navigation backgrounds
Warm Ivory (#F5F0E8) — content background, card surfaces
Coral Red (#E84B3A) — destructive actions, error states
Geometry
| CSS value | DESIGN.md language |
|---|
rounded-full | Pill-shaped, fully circular |
rounded-2xl | Generously rounded corners |
rounded-lg | Subtly rounded corners |
rounded-md | Slight corner softening |
rounded-none | Sharp, squared-off edges |
Elevation / Shadows
| CSS value | DESIGN.md language |
|---|
| No shadow | Flat, no elevation distinction |
shadow-sm | Whisper-soft diffused shadows |
shadow-md | Gentle card elevation |
shadow-lg | Pronounced depth, layered UI |
shadow-2xl | Heavy, high-contrast drop shadows |
Typography
Describe: font family character ("humanist sans-serif with geometric undertones"), weight hierarchy ("bold 700 for headings, regular 400 for body, never medium 500"), letter-spacing ("tight -0.02em tracking on headings").
DESIGN.md Output Format
# Design System: [Project Title]
**Project ID:** [numeric-id]
## 1. Visual Theme & Atmosphere
[2–3 sentences using sensory, evocative language. Capture density, mood, and aesthetic philosophy.]
## 2. Color Palette & Roles
| Name | Hex | Role |
|---|---|---|
| Deep Muted Teal-Navy | #294056 | Primary actions, navigation |
| ... | | |
## 3. Typography Rules
[Font family character, weight usage, letter-spacing, size hierarchy.]
## 4. Component Styling
- **Buttons:** [Shape, color assignment, hover/active behavior]
- **Cards/Containers:** [Corner roundness, background, shadow depth]
- **Inputs/Forms:** [Border style, background, focus ring]
## 5. Layout Principles
[Whitespace strategy, grid alignment, spacing rhythm, margin philosophy.]
Decision: Atmosphere Description
Before writing atmosphere, ask:
- What is the information density? (airy/dense)
- What emotion does it evoke? (calm/energetic/authoritative/playful)
- Who is the audience? (consumer/enterprise/developer)
- What is the visual weight? (lightweight/substantial)
These answers should generate 2–3 specific sentences — not adjective lists.
Arguments
$ARGUMENTS: Optional user-provided target, path, environment, symptom, or constraint. When empty, infer the narrowest safe scope from the current repository context and ask only if multiple high-impact choices remain.
