generating-stitch-screens

使用MCP工具从作者提示文件生成Stitch屏幕。读取提示章节,分别发送至Stitch生成,然后获取生成的图像与代码。当用户提到“在Stitch生成”、“创建Stitch屏幕”、“在Stitch运行提示”、“发送提示至Stitch”、“从提示生成屏幕”、“获取Stitch图像”或已有prompt-v*.md文件准备生成时,就使用此技能。需要Stitch MCP服务器。

  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:

code
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

  1. Read prompt file from design-intent/google-stitch/{feature}/prompt-v{N}.md
  2. Parse sections by --- separators, extracting <!-- Layout: --> and <!-- Component: --> markers
  3. Create or select project via MCP (create_project / list_projects)
  4. Generate screens — for each section: call generate_screen_from_text with prompt text
  5. Fetch images — for each screen: call fetch_screen_image at full resolution, save to {feature}/exports/ (see WORKFLOW.md for URL transformation)
  6. Fetch code (optional) — call fetch_screen_code, save to {feature}/code/
  7. Extract design context (optional) — call extract_design_context, save design DNA
  8. Report — project URL, screen list, file paths

Output Structure

code
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:

markdown
<!-- 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.
