Capture a structural snapshot of the node tree in a Pencil .pen file via the snapshot_layout MCP tool, optionally filtering to only show layout problems. Use when the user explicitly mentions Pencil and needs to analyze page hierarchy, check for clipped or overlapping elements, or prepare for layout adjustments.

Tools
This skill is designed to call the Pencil MCP tool:
snapshot_layout
If your client namespaces MCP tools, it may appear as mcp__pencil__snapshot_layout.
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. (e.g., "Analyze layout" might refer to HTML/CSS layout analysis).
CRITICAL PREREQUISITE: You must ONLY use this skill when the user EXPLICITLY mentions "Pencil".
ALWAYS use this skill when:
- You need to understand the hierarchy and layout relationship of nodes in Pencil.
- You are planning to move or align elements and need their current bounds.
- You need to check for "problems" like clipped content or overlapping elements.
- The user asks to "Analyze layout" or "Check structure" of a Pencil design.
Trigger phrases include:
- "Pencil snapshot layout" (Pencil 布局快照)
- "Analyze Pencil page structure" (分析 Pencil 页面结构)
- "Check Pencil layout problems" (检查 Pencil 布局问题)
- "Get Pencil node hierarchy" (获取 Pencil 节点层级)
Input Parameters
filePath(string, optional): Path to access a specific.penfile. Default is active document.maxDepth(integer, optional):- Limit how deep to descend in the node tree.
- Recommendation: Always specify a reasonable limit (e.g., 2 or 3) to avoid context overflow.
0means only top-level nodes.
parentId(string, optional): Only return layout for this node's subtree.problemsOnly(boolean, optional):- Set to
trueto only return nodes with layout issues (e.g., clipped by parent). - Default:
false.
- Set to
How to use this skill
- Determine Scope: Do you need the whole page (
maxDepth=1) or a specific section (parentId=...)? - Call Tool:
snapshot_layout(...). - Analyze Output: The result is a tree structure with layout information (bounds, constraints).
Examples
1. Simple: Top Level Snapshot
Get the layout of the top-level frames to see where empty space might be. See 1-top-level.json.
2. Medium: Specific Frame Layout
Get the layout structure of a specific frame to understand its children's positioning. See 2-specific-frame.json.
3. Complex: Layout Problems
Check for layout issues (like clipped content) deep within a specific section. See 3-layout-problems.json.
