Tools

This skill is designed to call the Pencil MCP tool:

  • get_editor_state

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

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. (e.g., "What is selected?" might refer to selected text in the IDE, not the Pencil canvas).

CRITICAL PREREQUISITE: You must ONLY use this skill when the user EXPLICITLY mentions "Pencil".

ALWAYS use this skill when:

  • You need to know what the user has currently selected on the canvas.
  • You need to check the active document path.
  • You are starting a new design task and need to orient yourself.
  • The user asks "What am I looking at?" or "Get context" in Pencil.

Trigger phrases include:

  • "Get Pencil editor state" (获取 Pencil 编辑器状态)
  • "Check current selection in Pencil" (检查 Pencil 当前选区)
  • "What is selected in Pencil?" (Pencil 中选中了什么?)
  • "Where am I on the Pencil canvas?" (我在 Pencil 画布哪里?)

Input Parameters

  • include_schema (boolean, optional):
    • Set to true if you want the .pen file schema to be included.
    • If you are already aware of the schema, set to false (default) to save context.

How to use this skill

  1. Call the MCP Tool: Invoke get_editor_state.
  2. Analyze Output:
    • Check selection: List of selected node IDs.
    • Check activePageId: Current page ID.
    • Check filePath: Path of the current document.

Examples

1. Simple: Basic State Check

Get the current state to understand what the user is looking at. See 1-basic-check.json.

2. Medium: State with Schema

Get state including the .pen file schema to understand the document structure definitions. See 2-with-schema.json.

3. Complex: State Verification (Explicit)

Explicitly checking state during a multi-step workflow where schema is already known. See 3-explicit-check.json.
