scene_export_report

Export complete scene structure and script dependency report as markdown file. Includes: hierarchy tree (built-in components name only, user scripts marked with *), user script fields with values, deep C# code-level dependencies (10 patterns: GetComponent<T>, FindObjectOfType<T>, SendMessage, field references, Singleton access, static member access, new T(), generic type args, inheritance/interface, typeof/is/as type checks), and merged dependency graph with risk ratings.

Parameter	Type	Required	Default	Description
savePath	string	No	"Assets/Docs/SceneReport.md"	Output file path
maxDepth	int	No	10	Max hierarchy depth
maxObjects	int	No	500	Max objects to export

Returns:

{
  "success": true,
  "savedTo": "Assets/Docs/SceneReport.md",
  "objectCount": 156,
  "userScriptCount": 5,
  "referenceCount": 12,
  "codeReferenceCount": 4
}

Markdown output sections:

1. Hierarchy — tree with component names, user scripts marked *
2. Script Fields — only user scripts (non-Unity namespace), with field values and reference targets
3. Code Dependencies — C# source analysis (comments stripped): GetComponent<T>, FindObjectOfType<T>, SendMessage, field references, inheritance (multi-class), static access (PascalCase only). Method-level location in From column.
4. Dependency Graph — table with columns: From | To | Type | Source | Detail. Source = scene (serialized reference) or code (source analysis). From shows ClassName.MethodName for code deps.

scene_dependency_analyze

Analyze object dependency graph and impact of changes. Use ONLY when user explicitly asks about dependency/impact analysis, safe to delete/disable, refactoring impact, or reference checks.

Parameter	Type	Required	Default	Description

  "totalReferences": 12,
  "objectsAnalyzed": 5,
  "analysis": [
    {
      "path": "Canvas/HUD/HealthBar",
      "risk": "medium",
      "dependedByCount": 3,
      "dependedBy": [
        {"source": "Player", "script": "PlayerController", "field": "healthUI", "fieldType": "Slider"}
      ],
      "dependsOnCount": 0,
      "dependsOn": null
    }
  ],
  "savedTo": "Assets/Docs/deps.md",
  "markdown": null
}
