Stitch to uni-app + uView 2.0 Components

Constraint: Only use this skill when the user explicitly mentions "Stitch" and converting Stitch screens to uni-app + Vue 2 + uView 2.0 (pages/, components/, .vue, u-* components).

You are a frontend engineer turning Stitch designs into clean, modular uni-app + uView 2 code. Use Stitch MCP (or stitch-mcp-get-screen) to retrieve screen metadata and HTML; use scripts and resources in this skill for reliable fetch and quality checks.

Prerequisites

• Stitch MCP Server (https://stitch.withgoogle.com/docs/mcp/guide/)
• uni-app / HBuilderX or Vue CLI for uni-app (Vue 2)
• Stitch project and screen IDs — two ways: (1) From a Stitch design URL: parse projectId (path) and screenId (node-id query). (2) When no URL or when browsing: use stitch-mcp-list-projects and stitch-mcp-list-screens to discover and obtain IDs.

Official Documentation

• uView 2.0 (Vue 2): Official · Guide / Demo · Components · GitHub
• Full links and usage: references/official.md

Retrieval and Networking

1. Discover Stitch MCP prefix: Run list_tools to find the prefix (e.g. mcp_stitch__stitch:).
2. Fetch screen metadata: Call [prefix]:get_screen with projectId and screenId (numeric IDs) to get design JSON, htmlCode.downloadUrl, screenshot.downloadUrl, dimensions, deviceType.
3. High-reliability HTML download: AI fetch tools can fail on Google Cloud Storage URLs. Use Bash to run the skill script:

   bash scripts/fetch-stitch.sh "<htmlCode.downloadUrl>" "temp/source.html"
   

   Ensure the URL is quoted.
4. Visual reference: Use screenshot.downloadUrl to confirm layout and details.

Architectural Rules

• Modular pages/components: Split the design into pages under pages/ and shared components under components/; avoid one giant page.
• Logic isolation: Put event handlers and mixins/utils in appropriate modules.
• Data decoupling: Move static text, image URLs, and lists into data/ or page data.
• uView 2 only (use framework components when available): Use u-* components per references/contract.md. Card-like blocks → u-cell-group + u-cell or u-text; hints/tips → u-text; dividers → u-line / u-divider. Do not use view/text + custom class (.card, .card-title, .label-optional, .tips-text, .unit).
• Project-specific: Omit third-party license headers from generated pages/components.

Execution Steps

1. Environment: Ensure uni-app project has uView 2 installed and configured (main.js, uni.scss).
2. Data layer: Create or update data sources (e.g. data/mockData.js) from the design content.
3. Page drafting: Use resources/page-template.vue as base; replace placeholder with real page name and uView 2 tags per contract.
4. Wiring: Register pages in pages.json; add tabBar or navigation as needed.
5. Quality check: Verify against resources/architecture-checklist.md; run in HBuilderX or CLI to confirm on simulator/device.

Integration with This Repo

• Get screen: Use stitch-mcp-get-screen with projectId and screenId. Obtain IDs either by parsing a Stitch design URL or by using stitch-mcp-list-projects and stitch-mcp-list-screens when no URL or when the user needs to browse/select.
• Design spec: If Stitch was generated with stitch-ui-design-spec-uview constraints, map to uni-app pages and uView 2 components. If converting from Stitch HTML (e.g. get_screen htmlCode), use references/tailwind-to-uview.md for Tailwind utility → rpx/theme, then references/contract.md for component API.
• Design system: If the project has DESIGN.md (from stitch-design-md), align colors and spacing with that system when mapping to uView tokens.

Troubleshooting

• Fetch errors: Quote the URL in the bash command; ensure scripts/fetch-stitch.sh is executable.
• Component mapping: Follow references/contract.md for layout (u-row, u-col), forms (u-form, u-input), nav (u-navbar, u-tabs), list (u-swipe-action), feedback (u-toast, u-modal).

Example: Stitch HTML to uView 2 Page

Stitch HTML with Tailwind card and button:

<div class="bg-white rounded-lg shadow p-4"><h2 class="text-lg font-bold">Profile</h2><button class="bg-blue-500 text-white px-4 py-2 rounded">Save</button></div>

Converted uView 2 page:

<template>
  <view class="page">
    <u-navbar title="Profile" :autoBack="true" />
    <u-cell-group>
      <u-cell title="Profile" />
    </u-cell-group>
    <u-button type="primary" text="Save" @click="handleSave" />
  </view>
</template>

Key mapping: div.rounded-lg.shadow becomes <u-cell-group>, raw <button> becomes <u-button type="primary">, Tailwind px maps to rpx.
