pencil-ui-design-system-uview
Initialize uView 2.x . design system components in Pencil variables and component overview.
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 you need to initialize a new design system based on uView 2.x 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 uView 2.x design tokens. Follow .pen file schema.
Primary / Semantic
u-type-primary:#3c9cffu-type-success:#5ac725u-type-warning:#f9ae3du-type-error:#f56c6cu-type-info:#909399
Text & Border
u-main-color:#303133u-content-color:#606266u-tips-color:#909399u-border-color:#e4e7edu-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.
Best Practices
- Verify token values against uView 2.x documentation (distinct from uView Pro).
- Use
set_variableswithreplace: falseunless 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)
- 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
- 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
- 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
- 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
- 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
