Unity Editor Skills

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

Operating Mode

• Approval：本模块 Mixed —— editor_get_selection / editor_get_context / editor_get_state / editor_get_tags / editor_get_layers 标 SkillMode.SemiAuto，可直接执行；其余 editor_select / editor_undo / editor_redo / editor_execute_menu 默认 FullAuto，Approval 模式下需 grant。
• Auto / Bypass：FullAuto 直接执行。
• 含 NeverInSemi 高危 skill：editor_play / editor_stop / editor_pause（标 MayEnterPlayMode = true，进出 PlayMode 会丢失运行时改动）。这些在 Approval/​Auto 下返 MODE_FORBIDDEN，仅 Bypass 或 Allowlist 命中可调。

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"

Skills Overview

---

Skills

editor_play

Enter play mode. Warning: any unsaved scene changes made during Play mode will be lost when exiting.

Returns: {success, mode, jobId} — mode="playing", jobId returned from AsyncJobService so callers can poll entering_play_mode completion.

editor_stop

Exit play mode.

Returns: {success, mode} — mode="stopped".

editor_pause

Toggle pause state.

Returns: {success, paused} — paused is the new boolean state.

editor_select

Select a GameObject.

*One identifier required

editor_get_selection

Get currently selected objects.

Returns: {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: {tags: [string]}

editor_get_layers

Get all available layers.

Returns: {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 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
