| description | Generates Stitch screens from authored prompt files using MCP tools. Reads prompt sections, sends each to Stitch for generation, and fetches resulting images and code. Use when user mentions "generate in stitch", "create stitch screens", "run prompts in stitch", "send prompts to stitch", "generate screens from prompts", "fetch stitch images", or has prompt-v*.md files ready for generation. Requires Stitch MCP server.

Generating Stitch Screens
Orchestrate screen generation in Google Stitch using MCP tools. Reads authored prompt files, sends each section to Stitch for generation, and fetches resulting images and code.
Prerequisites
Requires Stitch MCP server (@_davideast/stitch-mcp). If MCP tools are not available, display:
Stitch MCP is not configured.
Run /stitch-setup for guided setup, or see the plugin README for manual configuration.
Never fail silently. Always inform the user if MCP is unavailable.
Typically invoked via /stitch-generate or after prompt authoring with MCP available.
Quick Start
- Read prompt file from
design-intent/google-stitch/{feature}/prompt-v{N}.md
- Parse sections by
--- separators, extracting <!-- Layout: --> and <!-- Component: --> markers
- Create or select project via MCP (
create_project / list_projects)
- Generate screens — for each section: call
generate_screen_from_text with prompt text
- Fetch images — for each screen: call
fetch_screen_image at full resolution, save to {feature}/exports/ (see WORKFLOW.md for URL transformation)
- Fetch code (optional) — call
fetch_screen_code, save to {feature}/code/
- Extract design context (optional) — call
extract_design_context, save design DNA
- Report — project URL, screen list, file paths
Output Structure
design-intent/google-stitch/{feature}/
├── prompt-v{N}.md <- Source prompts
├── exports/ <- Generated images
│ ├── {layout-name}.png
│ ├── {component-1}.png
│ └── {component-2}.png
├── code/ <- Generated code (optional)
│ ├── {layout-name}/
│ └── {component-1}/
└── design-dna.md <- Extracted design context (optional)
Section Parsing
Prompt files use --- separators with HTML comment labels:
<!-- Layout: Analytics Dashboard -->
[layout prompt text]
---
<!-- Component: KPI Metrics -->
[component prompt text]
---
<!-- Component: Revenue Chart -->
[component prompt text]
Parse each section independently. Use the label text as the screen name in Stitch.
Error Handling
- Partial failure: If some screens fail to generate, continue with remaining sections and report failures
- Generation timeout: Wait, then retry once. If still pending, report and suggest checking Stitch directly
- Empty result from fetch: Generation may still be in progress — wait briefly and retry
Workflow Details
See WORKFLOW.md for detailed steps, error handling, and retry logic.
Examples
See EXAMPLES.md for end-to-end generation scenarios.
Troubleshooting
See TROUBLESHOOTING.md for MCP-specific issues.
