Tools
This skill is designed to call the Pencil MCP tool:
searchallunique_properties
If your client namespaces MCP tools, it may appear as mcppencilsearchallunique_properties.
When to use this skill
Intent Recognition (CRITICAL)
Even if a trigger phrase matches, you must verify the user's intent:
- Is the user explicitly asking to use "Pencil"?
- Is the current conversation context clearly about "Pencil" design tasks?
If the answer is NO, do NOT use this skill.
CRITICAL PREREQUISITE: You must ONLY use this skill when the user EXPLICITLY mentions "Pencil".
ALWAYS use this skill when:
- You are performing a Design Audit in Pencil.
- You need to find inconsistent usage (e.g., "Where did we use the wrong font?").
- You want to list all unique values for a specific property (e.g., "List all font sizes used").
Trigger phrases include:
- "Search Pencil properties" (搜索 Pencil 属性)
- "Find usage of color X in Pencil" (查找 Pencil 中颜色 X 的使用)
- "Audit Pencil fonts" (审计 Pencil 字体)
- "List unique values in Pencil" (列出 Pencil 唯一值)
Input Parameters
filePath(string, optional).parents(array, required): IDs of parent nodes to search within.properties(array, required): List of property names to search (e.g.,["fills", "typography"]).
How to use this skill
- Identify Scope: Determine which parent nodes (e.g., Root Frame) to audit.
- Call Tool:
searchallunique_properties(parents=[...], properties=["fills"]). - Analyze: The output groups nodes by property value.
Examples
1. Simple: Find All Colors
Audit all fill colors used in the document to identify inconsistencies.
{
"properties": ["fills"]
}2. Medium: Local Font Audit
Find all font families used within a specific frame (e.g., a card or section).
{
"parents": ["frame:card-123"],
"properties": ["fontFamily"]
}3. Complex: Comprehensive Style Audit
Search for fills, strokes, and font sizes across multiple key sections to generate a style report.
{
"parents": ["section:header", "section:footer"],
"properties": ["fills", "strokes", "fontSize", "fontFamily"]
}Keywords
English keywords: search properties, design audit, find usage, unique values, property check, style consistency
Chinese keywords (中文关键词): 搜索属性, 设计审计, 查找使用, 唯一值, 属性检查, 样式一致性
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
