Unity Editor Skills

Overview

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

Common Mistakes

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 editor_get_state (isCompiling field)
• For console errors → use native Unity_ReadConsole or Unity_GetConsoleLogs
• For scene save → scene_save (scene module) or editor_execute_menu menuPath="File/Save"

Skills Overview

Skills

editor_play

Enter play mode. Fire-and-forget: sets EditorApplication.isPlaying = true and returns { success, mode, started } immediately. Observe the transition by calling editor_get_state (check isPlaying) in a later call — recipes cannot span domain reloads.

editor_stop

Exit play mode.

editor_pause

Toggle pause state.

editor_select

Select a GameObject.

*One identifier required

editor_get_selection

Get currently selected objects.

Returns: {success, count, objects: [{name, instanceId}]}

editor_get_context

Get full editor context including selection, assets, and scene 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: {isPlaying, isPaused, isCompiling, timeSinceStartup, unityVersion, platform}

editor_execute_menu

Execute a menu command.

Common Menu Paths:

editor_get_tags

Get all available tags.

Returns: {success, tags: [string]}

editor_get_layers

Get all available layers.

Returns: {success, layers: [{index, name}]}

Pause On Error

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

Use console_set_pause_on_error from the console module.

Example Usage

See ../../recipes/editor/<command>.md for C# templates.

Recipe path rule: ../../recipes/editor/<command>.md

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
