pencil-mcp-search-all-unique-properties

Tools

This skill is designed to call the Pencil MCP tool:

• search_all_unique_properties

If your client namespaces MCP tools, it may appear as mcp__pencil__search_all_unique_properties.

When to use this skill

Intent Recognition (CRITICAL)

Even if a trigger phrase matches, you must verify the user's intent:

1. Is the user explicitly asking to use "Pencil"?
2. 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

1. Identify Scope: Determine which parent nodes (e.g., Root Frame) to audit.
2. Call Tool: search_all_unique_properties(parents=[...], properties=["fills"]).
3. 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)

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
