uView Design System Initializer

Constraint: Only use this skill when the user explicitly mentions "Pencil" and "uView" (2.x, not uView Pro) or when orchestrating a Pencil design system initialization task.

When to use this skill

Use this skill when:

The user wants to initialize uView 2.x tokens (primary, success, warning, error colors) in a Pencil .pen file
The user needs a component overview frame for uView 2.x components in Pencil
The user mentions "Pencil" together with "uView" (2.x, not Pro) or uView-specific components (Button, Cell, Tabs, Navbar)
An orchestrator skill (pencil-ui-designer) routes a uView 2.x initialization request

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 uView 2.x design tokens. Follow .pen file schema.

Primary / Semantic

u-type-primary: #3c9cff
u-type-success: #5ac725
u-type-warning: #f9ae3d
u-type-error: #f56c6c
u-type-info: #909399

Text & Border

u-main-color: #303133
u-content-color: #606266
u-tips-color: #909399
u-border-color: #e4e7ed
u-radius: 4px

Font

u-font-size-base: 14px (28rpx)

Fill from uView 2.x 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 uView 2.x documentation:

Basic (基础)
- Icon, Button, Layout, Cell, Badge, Tag
Form (表单)
- Form, Input, Textarea, Radio, Checkbox, Switch, Rate, Upload, Picker, Select, DatetimePicker, Search, NumberBox, CodeInput
Data (数据)
- Table, List, Calendar, CountDown, CountTo, Progress, CircleProgress
Feedback (反馈)
- ActionSheet, Modal, Toast, Notify, SwipeAction, Collapse, Popup
Layout (布局)
- Grid, Divider, Sticky, IndexList, Swiper, Waterfall
Navigation (导航)
- Navbar, Tabbar, Tabs, BackTop, Link, Section

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

Example: Initialize uView 2.x Variables

{
  "name": "set_variables",
  "arguments": {
    "filePath": "designs/app.pen",
    "replace": false,
    "variables": {
      "u-type-primary": "#3c9cff",
      "u-type-success": "#5ac725",
      "u-type-warning": "#f9ae3d",
      "u-type-error": "#f56c6c",
      "u-main-color": "#303133",
      "u-border-color": "#e4e7ed",
      "u-font-size-base": "14px"
    }
  }
}

Best Practices

Verify token values against uView 2.x documentation (distinct from uView Pro).
Use set_variables with replace: false unless a full reset is requested.
Use Auto Layout for component overview frames.
Keep each batch_design call to maximum 25 operations; split by category if needed.
