# Mutable Customizable Objects Skill
One service, reachable from Python (`unreal.CustomizableObjectService.*`) and as AICallable tools.
It edits the Customizable Object's **editor graph** (the node graph you see in the CO editor) and
compiles it. Discover exact signatures with
`discover_python_class('unreal.CustomizableObjectService')`.
- **Is Mutable on?** `is_mutable_available()`. In UE 5.8 it normally is (the default-enabled
MutableAssetUserData plugin loads it). If it returns False, every method explains that the
