Stitch to uni-app + uView Pro Components

Constraint: Only use this skill when the user explicitly mentions "Stitch" and converting Stitch screens to uni-app + Vue 3 + uView Pro (pages/, components/, .vue or .uvue, u-* components).

You are a frontend engineer turning Stitch designs into clean, modular uni-app + uView Pro 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 3)
• Stitch project and screen IDs — two ways: (1) From a Stitch design URL: parse projectId from path and screenId from node-id query (see stitch-mcp-get-screen). (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 Pro (Vue 3): Official · Guide · Components · Tools · Layout / Templates
• 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. Resolve projectId and screenId: (1) If the user provided a Stitch design URL, parse projectId from the path (segment after /projects/) and screenId from the node-id query parameter. (2) Otherwise, or when the user wants to choose a project/screen, call list_projects (e.g. filter view=owned) then list_screens with the chosen projectId to get screenIds.
3. Fetch screen metadata: Call [prefix]:get_screen with projectId and screenId to get design JSON, htmlCode.downloadUrl, screenshot.downloadUrl, dimensions, deviceType.
4. 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.
5. 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: Use <script setup>; put event handlers and composables in appropriate modules.
• Data decoupling: Move static text, image URLs, and lists into data/ or page data.
• uView Pro only (use framework components when available): Use u-* components only; do not use raw <button>, <input>, <div> for buttons/inputs/modals when u-* exists. Use u-card for cards (use title when only a title, or u-section with #right when title + right content), u-text for label hints and tips (type="info"/"warning", size="24"), u-line / u-divider for dividers; do not use view/text + custom class (.card, .card-title, .label-optional, .tips-text, .unit). Tab bar must use u-tabs; do not use custom tab-header/tab-item. Before drafting a page, read references/component-index.md and references/contract.md for mapping rules, slot syntax (#label, #suffix, #right), and anti-patterns (Picker v-model + :range 1D; Radio value not name; no slot="...").
• Project-specific: Omit third-party license headers from generated pages/components.

Execution Steps

1. Environment: Ensure uni-app project has uView Pro installed and configured (Vue 3, 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 Pro 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.

Official API alignment (avoid Stitch-style mistakes)

When converting Stitch HTML to uView Pro, verify against references/contract.md and uView Pro docs. Common corrections:

Element	Wrong (often from Stitch/other UI)	Correct (uView Pro)
Tab switcher	Custom <view class="tab-header"> + <view class="tab-item">	Always use <u-tabs :list="..." :current="..." @change="...">; do not build tabs with raw views/divs
Tabs props	lineColor, activeStyle, inactiveStyle, itemStyle	:current, @change(index) (number), active-color, inactive-color
Picker	:show="show", :columns="[['A','B']]" (2D)	v-model="show"; mode="selector" + :range (1D array, e.g. ['A','B']); @confirm; do not use :columns
Radio	name="opt1", customStyle, placement="row"	value="opt1" (not name), label for text; no customStyle/placement
Slots (Vue 3)	slot="label", slot="suffix"	#label, #suffix, v-slot:label — never slot="..."
Form-item label	slot="label"	#label or v-slot:label
Input type=select	—	Pair with u-picker; use :select-open bound to picker visibility

Pre-generation checklist — before writing the template, ensure: (1) Card/section use u-card (with title or + u-section for title+right), not view.card + card-header + card-title. (2) Label hints and tips use u-text (type="info"/"warning", size="24"), not text with .label-optional/.tips-text/.unit. (3) Divider use u-line or u-divider, not view + border. (4) Tab switcher uses u-tabs, not custom divs. (5) All slots use #slotname or v-slot:slotname. (6) Picker uses v-model and :range (1D). (7) Radio uses value and label, not name/customStyle/placement.

Integration with This Repo

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

Troubleshooting

• Fetch errors: Quote the URL in the bash command; ensure scripts/fetch-stitch.sh is executable.
• Component mapping: Use references/component-index.md to pick the right u-* for each element; follow references/contract.md for layout (u-row, u-col, u-gap), forms (u-form, u-input), nav (u-navbar, u-tabs, u-tabbar), list (u-swipe-action, u-list), feedback (u-toast, u-modal, u-popup, u-empty, uni.$u). Do not substitute raw HTML for u-* components.

Skill testing (command-triggered)

Testing is triggered by user instruction, not by calling MCP directly. Flow: user pastes the test command below into the chat → Agent runs this skill → resolve URL → call get_screen → fetch/parse design → generate uView Pro code → output page file or full code.

• Test command (paste into Cursor chat):

  Use the Stitch skill to convert https://stitch.withgoogle.com/projects/3492931393329678076?node-id=375b1aadc9cb45209bee8ad4f69af450 into a uView Pro page
  

• Expected: Parse projectId and screenId from URL → call Stitch MCP get_screen → generate uni-app + uView Pro .vue (u-navbar, u-tabs, u-form, u-picker, u-radio, etc.) per contract and stitch-html-patterns.
