uView Design Spec (uView 2.0 / uni-app / Vue2)

Constraint: Only use this skill when the user explicitly mentions "Stitch".

Purpose

This skill makes the uView 2.0 design spec executable in two modes:

1. Prefix mode: output a paste-ready Hard constraints prefix for Stitch [Context].
2. Selector mode: output CONTRACT_SELECTION_JSON_V1 and then an assembled Stitch prompt that injects only the required component/state snippets.

Trigger Keywords

Prefer this skill when the user request includes any of:

• uview, uview2, uview2.0, u-view

Negative Constraint: If the user says "uView Pro" or "uviewpro", DO NOT use this skill. Use stitch-ui-design-spec-uviewpro instead.

Chinese trigger keywords (only for triggering):

• uview 风格
• 美化
• 优化

Source of Truth

• references/contract.md
• references/examples.md
• references/official.md

Output (STRICT)

Decide the mode by the user intent:

• If the user asks for beautify/polish/refine an existing screen, or asks for selector / JSON / contracts.include / states.include → use Selector mode.
• Otherwise → use Prefix mode.

Prefix mode

Return exactly one code block:

[Hard constraints prefix]
- Framework: uView 2.0 (uni-app / Vue 2).
- Design Tokens:
  - Colors: Primary=#3c9cff, Success=#5ac725, Warning=#f9ae3d, Error=#f56c6c, Info=#909399.
  - Background: #f3f4f6. Border: #dadbde.
  - Spacing: 4, 8, 12, 16, 20, 24, 32, 40 (px).
  - Radius: 8, 12, 999 (px).
- Component Contracts:
  - Layout: Use <u-row> and <u-col span="...">.
  - Forms: Use <u--form> (note double dash), <u--input border="surround">.
  - Buttons: Use <u-button type="primary">.
  - Navbar: Use <u-navbar title="..." :autoBack="true">.
  - List: <u-swipe-action>, <u-index-list>, <u-waterfall>.
  - Feedback: Use this.$refs.uToast.show({...}), <u-code> (SMS).
- Layout Invariants:
  - No gradients as default style.
  - Minimal shadows.
  - Transitions: 200ms ease-out.

Selector mode

Return exactly two code blocks, in this order, with no extra prose:

1. Contract selection JSON:

{
  "version": "CONTRACT_SELECTION_JSON_V1",
  "designSystem": "uview2",
  "mode": "selector",
  "contracts": { "include": [] },
  "states": { "include": [] }
}

2. Final Stitch prompt:

[Context]
(Paste Hard Constraints Prefix here)
(Add "Layout Invariants" from contract.md if beautifying)

[Layout]
(Describe the macro layout structure, e.g., "Mobile Column Layout with Navbar")

[Components]
(Inject component snippets matching the JSON selection above)

能力边界

✅ 适用场景

• 当你需要使用此技能对应的技术栈时
• 当项目需要遵循最佳实践时
• 当需要快速上手或深入理解核心概念时

⚠️ 需要注意

• 复杂业务逻辑需要结合具体场景调整
• 性能优化需要根据实际数据量评估

❌ 不适用场景

• 不相关的技术栈或框架
• 需要完全自定义的特殊场景

常见陷阱 (Gotchas)

1. 版本兼容性：注意框架版本与依赖库的兼容性，不同版本 API 可能有差异
2. 配置文件格式：配置文件格式错误是最常见的问题，建议使用编辑器的语法检查
3. 环境变量：确保所有必要的环境变量已正确设置，敏感信息不要硬编码
4. 依赖冲突：多版本共存时注意依赖冲突，使用 lock 文件锁定版本
5. 性能陷阱：大数据量场景下注意性能优化，避免 N+1 查询等常见问题

Step 1: 环境准备

确保开发环境已安装必要的依赖和工具。

Step 2: 配置初始化

根据项目需求进行基础配置。

Step 3: 核心功能使用

按照示例代码实现核心功能。

Step 4: 测试验证

运行测试确保功能正常。

Step 5: 部署上线
