Expose this level clean-up function as a tool the agent can call through unreal-mcp.About this skill
Use this skill when authoring or extending an Unreal Engine toolset, a class of static, AI-callable functions registered with ToolsetRegistry and exposed through the unreal-mcp server. Trigger when the user wants to add, expose, or register a new tool method, create a new toolset, or extend an existing one such as BlueprintTools, StaticMeshTools, ObjectTools, LevelTools, or MaterialTools. SKIP for: invoking existing tools at runtime (use unreal-mcp instead), authoring an Agent Skill (use unreal-skill), generic refactors that happen to touch a toolset file but don't add or redesign a tool, or unrelated uses of the word 'toolset'.
