// Control Unity Editor Play Mode. Use to start, stop, or pause Play Mode for runtime behavior checks and frame inspection.
Use when Unity Editor is not running or needs a clean restart.
Clear Unity Console entries. Use before compile, tests, or debugging when stale logs would hide the current result.
Compile the Unity project and report errors/warnings. Use after C# edits or when a full Domain Reload compile is needed.
Execute C# with Unity APIs when existing uloop tools cannot inspect or edit enough. Use for scene, prefab, SerializedObject, AssetDatabase refresh/.meta generation, menu, or PlayMode automation.
Find or inspect Unity GameObjects, especially objects the user currently selected in the Hierarchy. Use for details, components, tags, layers, or name/path searches.
Get the Unity scene hierarchy as a structured tree. Use for parent-child structure, descendants, roots, or subtrees under objects the user currently selected.
