Unity Editor Skills

Control the Unity Editor itself - enter play mode, manage selection, undo/redo, and execute menu items.

Guardrails

Mode: Semi-Auto (available by default)

DO NOT (common hallucinations):

• editor_run does not exist → use editor_play to enter play mode
• editor_compile / editor_recompile do not exist → use debug_force_recompile
• editor_save does not exist → use editor_execute_menu with menuPath "File/Save"
• editor_execute_menu requires exact menu path — typos cause silent failure

Routing:

• For compilation check → use debug module's debug_check_compilation
• For console errors → use debug module's debug_get_errors
• For scene save → scene_save (scene module) or editor_execute_menu menuPath="File/Save"

*One identifier required

editor_get_selection

Parameter	Type	Required	Default	Description
includeComponents	bool	No	false	Include component list
includeChildren	bool	No	false	Include children info

Returns:

• selectedGameObjects: Objects in Hierarchy (instanceId, path, tag, layer)
• selectedAssets: Assets in Project window (GUID, path, type, isFolder)
• activeScene: Current scene info (name, path, isDirty)
• focusedWindow: Name of focused editor window
• isPlaying, isCompiling: Editor state

editor_undo

Undo the last action.

editor_redo

Redo the last undone action.

editor_get_state

Get current editor state.

Returns: {success, isPlaying, isPaused, isCompiling, platform}

editor_execute_menu

Execute a menu command.

Parameter	Type	Required	Description
menuPath	string	Yes	Menu item path

Common Menu Paths:

Menu Path	Action
File/Save	Save current scene
File/Build Settings...	Open build settings
Edit/Play	Toggle play mode
GameObject/Create Empty	Create empty object
Window/General/Console	Open console
Assets/Refresh	Refresh assets

editor_get_tags

Returns: {success, tags: [string]}

editor_get_layers

Get all available layers.

Pause On Error

Pause-on-error is provided by the console module, not the editor module.

Use console_set_pause_on_error from console/SKILL.md.

Example Usage

import unity_skills

# Check editor state before operations
state = unity_skills.call_skill("editor_get_state")
if state['isCompiling']:
    print("Wait for compilation to finish")

# Get full context (useful for understanding current state)
context = unity_skills.call_skill("editor_get_context", includeComponents=True)
for obj in context['selectedGameObjects']:
    print(f"Selected: {obj['name']} (ID: {obj['instanceId']})")

# Select and operate on object
unity_skills.call_skill("editor_select", name="Player")
selection = unity_skills.call_skill("editor_get_selection")

# Safe experimentation with undo
unity_skills.call_skill("gameobject_delete", name="TestObject")
unity_skills.call_skill("editor_undo")  # Restore if needed

# Execute menu command
unity_skills.call_skill("editor_execute_menu", menuPath="File/Save")

Best Practices

1. Check editor state before play mode operations
2. Don't modify scene during play mode (changes lost)
3. Use undo for safe experimentation
4. Use editor_get_context to get instanceId for batch operations
5. Menu commands must match exact paths
