Search and list all unique values for specific properties (fills, fonts, spacing) across nodes in a Pencil .pen file via the search_all_unique_properties MCP tool. Use when the user explicitly mentions Pencil and needs to audit design consistency, find all colors or font sizes used, or identify inconsistent styles.

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:
- 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:
search_all_unique_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"]
}
