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.

Read current Unity Console entries from a running Editor. Use during bug investigation after compile, tests, PlayMode, or dynamic code to inspect logs, warnings, errors, and stack traces.

Control Unity Editor play mode via uloop CLI. Use when you need to: (1) Start play mode for testing, (2) Stop play mode after testing, (3) Pause play mode for debugging.

Returns the Unity version. Use this tool to check Unity environment information.

Clear all Unity Console log entries. Use when you need to: (1) Clear console before running tests or compilation, (2) Start a fresh debugging session, (3) Remove noisy logs to isolate specific output.

Compile Unity project and report errors/warnings. Use when you need to: (1) Verify code compiles after C# file edits, (2) Check for compile errors before testing, (3) Force full recompilation with Domain Reload. Returns error and warning counts.

Control Unity Editor play mode (play/stop/pause). Use when you need to: (1) Start play mode to test game behavior, (2) Stop play mode to return to edit mode, (3) Pause play mode for frame-by-frame inspection.
