1# Create Toolset
2 
3You are authoring or extending an Unreal Engine toolset: a collection of static, AI-callable functions registered with the `ToolsetRegistry` and exposed through the MCP server. The goal is to expand the surface of things Claude can do inside the editor.

5## Principles

7A good toolset is:
8 
9**Clean**: Design the simplest API that can do useful work in the domain. Don't mirror Unreal's existing APIs directly; they're often unnecessarily complex. A good heuristic: would a technical artist understand this without reading the implementation?
10 
11**Complete**: Support CRUD symmetry. If you can set a thing, you should be able to get it. If there's a create, there should be a delete. Getters without setters are fine when mutation isn't possible or useful.
12 
13**Composable**: Use consistent types for the same kinds of operation across the toolset. If `get_graph()` returns a `Graph`, then `get_graph_nodes()` should accept a `Graph`. Functions should combine naturally to produce more complex results.
14 
15**DRY**: No duplication within a toolset, and no duplication across toolsets. `ObjectTools` already provides generic UObject property get/set. Don't reimplement it. If functionality lives elsewhere, call it or point to it.
