Design System Synthesis

— Analyze existing Stitch projects to create

.stitch/DESIGN.md

"source of truth" documents.

Workflow Routing

— Intelligently route user requests to specialized generation or editing workflows.

Consistency Management

— Ensure all new screens leverage the project's established visual language.

Asset Management

— Automatically download generated HTML and screenshots to the

.stitch/designs

🎨 Prompt Enhancement Pipeline

Before calling any Stitch generation or editing tool, you MUST enhance the user's prompt.

1. Analyze Context

Project Scope

Maintain the current

projectId

. Use

list_projects

if unknown.

Design System

Check for

.stitch/DESIGN.md

. If it exists, incorporate its tokens (colors, typography). If not, suggest the

generate-design-md

workflow.

2. Refine UI/UX Terminology

Consult

Design Mappings

to replace vague terms.

Vague: "Make a nice header"

Professional: "Sticky navigation bar with glassmorphism effect and centered logo"

3. Structure the Final Prompt

Format the enhanced prompt for Stitch like this:

[Overall vibe, mood, and purpose of the page]

DESIGN SYSTEM (REQUIRED):

-

Platform: [Web/Mobile], [Desktop/Mobile]-first

-

Palette: [Primary Name] (#hex for role), [Secondary Name] (#hex for role)

-

Styles: [Roundness description], [Shadow/Elevation style]

PAGE STRUCTURE:

1.

Header:

[Description of navigation and branding]

2.

Hero Section:

[Headline, subtext, and primary CTA]

3.

Primary Content Area:

[Detailed component breakdown]

4.

Footer:

[Links and copyright information]

4. Present AI Insights

After any tool call, always surface the

outputComponents

(Text Description and Suggestions) to the user.

💡 Best Practices

Iterative Polish

Prefere

edit_screens

for targeted adjustments over full re-generation.

Semantic First

Name colors by their role (e.g., "Primary Action") as well as their appearance.
Atmosphere Matters: Explicitly set the "vibe" (Minimalist, Vibrant, Brutalist) to guide the generator.
