Element Plus Design Spec (Element Plus / Vue 3)

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

Purpose

This skill makes the Element Plus 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:

• element, element-plus, el-plus, element-ui

Chinese trigger keywords (only for triggering):

• element 风格
• 饿了么组件库
• 后台管理系统 (if context implies Element Plus)

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: Element Plus (Vue 3).
- Design Tokens:
  - Colors: Primary=#409EFF (Blue), Success=#67C23A, Warning=#E6A23C, Danger=#F56C6C, Info=#909399.
  - Typography: Font-family: "Helvetica Neue", Helvetica, "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif.
  - Radius: Small=2px, Base=4px, Round=20px.
- Component Contracts:
  - Layout: Use <el-row :gutter="20"> and <el-col :span="...">. Container: <el-container>, <el-header>, <el-main>.
  - Buttons: Use <el-button type="primary" plain/round>.
  - Forms: Use <el-form>, <el-form-item>, <el-input>, <el-select>, <el-switch>, <el-checkbox>.
  - Data: <el-table>, <el-descriptions>, <el-timeline>, <el-carousel>, <el-empty>.
  - Cards: Use <el-card shadow="hover"> with #header slot.
  - Icons: Use <el-icon><Edit /></el-icon> (from @element-plus/icons-vue).
  - Navigation: <el-menu>, <el-breadcrumb>, <el-tabs>, <el-steps>.
  - Feedback: Use ElMessage.success() for JS feedback, <el-alert>, <el-dialog>, <el-drawer>.
- Layout Invariants:
  - Always use 24-column grid system.
  - Use el-space for inline spacing.

Selector mode

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

1. Contract selection JSON:

{
  "version": "CONTRACT_SELECTION_JSON_V1",
  "designSystem": "element-plus",
  "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., "Admin Dashboard Layout with Sidebar")

[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 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

完成开发后进行部署和监控。
