uView Pro Design System Initializer
Constraint: Only use this skill when the user explicitly mentions "Pencil" and "uView Pro" (or "uviewpro") or when orchestrating a Pencil design system initialization task.
When to use this skill
Use this skill when:
- The user wants to initialize uView Pro tokens (primary, error, warning, success colors) in a Pencil .pen file
- The user needs a component overview frame for uView Pro components in Pencil
- The user mentions "Pencil" together with "uView Pro", "uviewpro", or uView Pro-specific components (Button, Form, Tabs, Navbar)
- An orchestrator skill (pencil-ui-designer) routes a uView Pro 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 the following uView Pro design tokens. Follow .pen file schema; variable names are arbitrary strings.
Primary Colors (Blue)
u-type-primary:#2979ffu-type-primary-dark:#2b85e4u-type-primary-disabled:#a0cfffu-type-primary-light:#ecf5ff
Error Colors (Red)
u-type-error:#fa3534u-type-error-dark:#dd6161u-type-error-disabled:#fab6b6u-type-error-light:#fef0f0
Warning Colors (Yellow)
u-type-warning:#ff9900u-type-warning-dark:#f29100u-type-warning-disabled:#fcbd71u-type-warning-light:#fdf6ec
Success Colors (Green)
u-type-success:#19be6bu-type-success-dark:#18b566u-type-success-disabled:#71d5a1u-type-success-light:#dbf1e1
Info Colors (Gray)
u-type-info:#909399u-type-info-dark:#82848au-type-info-disabled:#c8c9ccu-type-info-light:#f4f4f5
Text Colors
u-main-color:#303133(Main Text)u-content-color:#606266(Content Text)u-tips-color:#909399(Tips/Secondary)u-light-color:#c0c4cc(Placeholder)
Background & Border
u-bg-color:#f3f4f6u-border-color:#e4e7ed
Font Sizes (px)
u-font-xs:12px(24rpx)u-font-sm:13px(26rpx)u-font-md:14px(28rpx)u-font-lg:15px(30rpx)u-font-xl:16px(32rpx)
Border Radius
u-radius:4px(8rpx)u-radius-lg:8px(16rpx)u-radius-circle:9999px
Step 2: Create Component Overview Structure (batch_design)
Use mcp__pencil__batch_design to create a "Components Overview" frame containing the following sections (Frames) based on uView Pro documentation:
- Basic Components (基础组件)
- Color, Icon, Image, Button, Layout, Cell, Badge, Tag, Text, Fab, Transition, TodoRootPortal, ConfigProvider
- Form Components (表单组件)
- Form, Input, Textarea, Calendar, Select, Keyboard, Picker, Rate, Search, NumberBox, Upload, VerificationCode, Field, Checkbox, Radio, Switch, Slider
- Data Components (数据组件)
- CircleProgress, LineProgress, Table, CountDown, CountTo
- Feedback Components (反馈组件)
- ActionSheet, AlertTips, Toast, NoticeBar, TopTips, Collapse, Popup, SwipeAction, Modal, FullScreen
- Layout Components (布局组件)
- Line, Card, Mask, NoNetwork, Grid, Swiper, TimeLine, Skeleton, Sticky, Waterfall, Divider
- Navigation Components (导航组件)
- Dropdown, Tabbar, BackTop, Navbar, Tabs, TabsSwiper, Subsection, IndexList, Steps, Empty, Link, Section, Pagination
- Other Components (其他组件)
- MessageInput, Loadmore, TodoReadMore, LazyLoad, Gap, Avatar, Loading, LoadingPopup, safeAreaInset
Organize component frames using Auto Layout. Keep each batch_design call to maximum 25 operations; split by logical sections if needed.
Example: Initialize uView Pro Variables
{
"name": "set_variables",
"arguments": {
"filePath": "designs/app.pen",
"replace": false,
"variables": {
"u-type-primary": "#2979ff",
"u-type-error": "#fa3534",
"u-type-warning": "#ff9900",
"u-type-success": "#19be6b",
"u-main-color": "#303133",
"u-bg-color": "#f3f4f6",
"u-border-color": "#e4e7ed",
"u-font-md": "14px"
}
}
}
Best Practices
- Always verify color values against the latest uView Pro documentation if unsure.
- Use
set_variableswithreplace: falseto merge into existing variables unless a full reset is requested. - Organize component frames using Auto Layout for easy expansion.
- Keep each
batch_designcall to maximum 25 operations; split by category if needed.
