Element Plus Design System Initializer

Constraint: Only use this skill when the user explicitly mentions "Pencil" and "Element" (or "Element Plus") or when orchestrating a Pencil design system initialization task.

When to use this skill

Use this skill when you need to initialize a new design system based on Element Plus specifications, specifically to set up the global color palette and create the initial component library frames in a .pen file.

How to use this skill

This skill outputs a PENCIL_PLAN. The Agent then calls Pencil MCP tools in order: open_document, set_variables, batch_design, optionally get_screenshot.

Step 1: Initialize Variables (set_variables)

Use mcp__pencil__set_variables to register Element Plus design tokens. Follow .pen file schema.

Primary / Semantic

• el-color-primary: #409eff
• el-color-success: #67c23a
• el-color-warning: #e6a23c
• el-color-danger: #f56c6c
• el-color-info: #909399

Text & Border

• el-text-color-primary: #303133
• el-text-color-regular: #606266
• el-text-color-secondary: #909399
• el-border-color: #dcdfe6
• el-border-radius-base: 4px

Font

• el-font-size-base: 14px

Fill from Element Plus theme docs if more tokens are needed.

Step 2: Create Component Overview Structure (batch_design)

Use mcp__pencil__batch_design to create a "Components Overview" frame with sections based on Element Plus documentation:

1. Basic (基础)
   • Button, Link, Icon
2. Layout (布局)
   • Container, Grid, Divider
3. Form (表单)
   • Radio, Checkbox, Input, InputNumber, Select, Cascader, Switch, Slider, TimePicker, DatePicker, DateTimePicker, Form, Upload, Rate
4. Data (数据)
   • Table, Tag, Progress, Tree, Pagination, Avatar, Skeleton, Empty
5. Navigation (导航)
   • Menu, Tabs, Breadcrumb, PageHeader, Dropdown, Steps
6. Feedback (反馈)
   • Alert, Loading, Message, MessageBox, Notification, Dialog, Drawer, Popover, Tooltip

Organize frames using Auto Layout. Keep each batch_design call to maximum 25 operations.

Best Practices

• Verify token values against Element Plus theme documentation.
• Use set_variables with replace: false unless a full reset is requested.
• Use Auto Layout for component overview frames.

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
