# 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](https://uviewpro.cn/) · [Guide](https://uviewpro.cn/zh/guide/intro.html) · [Components](https://uviewpro.cn/zh/components/intro.html) · [Tools](https://uviewpro.cn/zh/tools/intro.html) · [Layout / Templates](https://uviewpro.cn/zh/layout/intro.html)
- Full links and usage: [references/official.md](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
   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](references/component-index.md)** and [references/contract.md](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](references/contract.md) and [uView Pro docs](https://uviewpro.cn/zh/components/intro.html)**. 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](references/stitch-html-patterns.md) for page structure and form fields; [references/tailwind-to-uviewpro.md](references/tailwind-to-uviewpro.md) for Tailwind utility → rpx/theme (spacing, typography, colors, borders, shadows); then [references/contract.md](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](references/component-index.md) to pick the right u-* for each element; follow [references/contract.md](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):
  ```text
  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.
