Full-stack-skills pencil-mcp-replace-all-matching-properties

Batch replace matching style properties (colors, fonts, sizes) across nodes in a Pencil .pen file via the replace_all_matching_properties MCP tool. Use when the user explicitly mentions Pencil and needs to globally swap colors, update font families, migrate to a new brand style, or batch-adjust spacing across frames.

mcp__pencil__replace_all_matching_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. (e.g., "Replace properties" might refer to refactoring code).

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

ALWAYS use this skill when:

You need to make Global Changes or Batch Updates in Pencil.
The user asks to "Change all X to Y".
You are refactoring styles (e.g., "Replace hex codes with variables").

Trigger phrases include:

"Replace Pencil properties" (替换 Pencil 属性)
"Change all colors in Pencil" (修改 Pencil 所有颜色)
"Batch update Pencil fonts" (批量更新 Pencil 字体)
"Pencil global style replace" (Pencil 全局样式替换)

Input Parameters

filePath
(string, optional).
parents
(array, required): IDs of parent nodes to search within.

```
property
```
  ,
```
match
```
  (value to find), and
```
replace
```
  (new value).

How to use this skill

Define Rules: "Find
```
fills: #FF0000
```

```
".
Call Tool:
```

to verify the global change.

Examples

1. Simple: Global Color Swap

Replace all instances of Red (#FF0000) with Blue (#0000FF) across the entire document.

{
  "properties": [
    {
      "property": "fills",
      "from": { "color": "#FF0000" },
      "to": { "color": "#0000FF" }
    }
  ]
}

2. Medium: Local Font Update

Change the font family from "Arial" to "Roboto" only within the Footer section.

{
  "parents": ["frame:footer"],
  "properties": [
    {
      "property": "fontFamily",
      "from": "Arial",
      "to": "Roboto"
    }
  ]
}

3. Complex: Batch Style Migration

Update multiple properties (color and font) simultaneously across several frames to migrate to a new brand style.

{
  "parents": ["frame:home", "frame:profile"],
  "properties": [
    {
      "property": "fills",
      "from": { "color": "#OLD_COLOR" },
      "to": { "color": "#NEW_COLOR" }
    },
    {
      "property": "fontSize",
      "from": 12,
      "to": 14
    }
  ]
}
