description	| Use when this capability is needed.

Purpose

Unity Editor Toolkit enables comprehensive Unity Editor automation and control from Claude Code. It provides:

• Extensive Command Coverage: 500+ commands spanning 25 Unity Editor categories
• Real-time Communication: Instant bidirectional WebSocket connection (JSON-RPC 2.0)
• SQLite Database Integration: Real-time GameObject synchronization with GUID-based persistence
  • GUID-based Identification: Persistent GameObject tracking across Unity sessions
  • Multi-scene Support: Synchronize all loaded scenes simultaneously (1s interval)
  • Command Pattern: Undo/Redo support for database operations
  • Auto Migration: Automatic schema migration system
  • Batch Operations: Efficient bulk inserts, updates, and deletes (500 objects/batch)
• Menu Execution: Run Unity Editor menu items programmatically (Window, Assets, Edit, GameObject menus)
• ScriptableObject Management: Complete CRUD operations with array/list support and all field types
  • Array/List Operations: Add, remove, get, clear elements with nested access (items[0].name)
  • All Field Types: Integer, Float, String, Boolean, Vector*, Color, Quaternion, Bounds, AnimationCurve, ObjectReference, and more
  • Nested Property Traversal: Access deeply nested fields with dot notation and array indices
• Deep Editor Integration: GameObject/hierarchy, transforms, components, scenes, materials, prefabs, animation, physics, lighting, build pipeline, and more
• Security First: Multi-layer defense against injection attacks (SQL, command, JSON, path traversal) and unauthorized access
• Production Ready: Cross-platform support with robust error handling and logging

Always run scripts with --help first to see usage. DO NOT read the source until you try running the script first and find that a customized solution is abslutely necessary. These scripts can be very large and thus pollute your context window. They exist to be called directly as black-box scripts rather than ingested into your context window.

📚 문서 우선 원칙 (필수)

⚠️ CRITICAL: Unity Editor Toolkit skill을 사용할 때는 반드시 다음 순서를 따르세요:

1️⃣ Reference 문서 확인 (필수)

명령어를 사용하기 전에 반드시 skills/references/ 폴더의 해당 문서를 읽으세요:

• COMMANDS.md - 모든 명령어의 카테고리 및 개요
• Category-specific docs - 사용할 명령어의 카테고리 문서:
  • Component Commands - comp list/add/remove/enable/disable/get/set/inspect/move-up/move-down/copy
  • GameObject Commands - go find/create/destroy/set-active/set-parent/get-parent/get-children
  • Transform Commands - tf get/set-position/set-rotation/set-scale
  • Scene Commands - scene current/list/load/new/save/unload/set-active
  • Console Commands - console logs/clear
  • EditorPrefs Commands - prefs get/set/delete/list/clear/import

2️⃣ --help 실행

# 모든 명령어 확인
cd <unity-project-root> && node .unity-websocket/uw --help

# 특정 명령어의 옵션 확인
cd <unity-project-root> && node .unity-websocket/uw <command> --help

3️⃣ 예제 실행

reference 문서의 Examples 섹션을 참고하여 명령어를 실행하세요.

4️⃣ 소스 코드 읽기 (최후의 수단)

• reference 문서와 --help만으로는 해결 안 될 때만 소스 코드를 읽으세요
• 소스 코드는 컨텍스트 윈도우를 많이 차지하므로 가능하면 피하세요

이 순서를 무시하면:

• ❌ 명령어 사용법을 잘못 이해할 수 있음
• ❌ 옵션을 놓쳐서 원하지 않는 결과가 나올 수 있음
• ❌ 컨텍스트 윈도우를 낭비할 수 있음

Claude Code Plugin

The Unity Editor Toolkit plugin provides CLI commands for Unity Editor control.

Core Workflow

1. Connection

Unity Editor Toolkit CLI automatically:

• Detects Unity project via .unity-websocket/server-status.json
• Reads port information from status file (9500-9600 range)
• Connects to WebSocket server if Unity Editor is running

2. Execute Commands

⚠️ Before executing ANY command, check the reference documentation for your command category (see "📚 문서 우선 원칙" section above).

Unity Editor Toolkit provides 86+ commands across 15 categories. All commands run from the Unity project root:

cd <unity-project-root> && node .unity-websocket/uw <command> [options]

3. Check Connection Status

# Verify WebSocket connection
cd <unity-project-root> && node .unity-websocket/uw status

# Use custom port
cd <unity-project-root> && node .unity-websocket/uw --port 9301 status

4. Complex Workflows

Create and configure GameObject:

cd <unity-project-root> && node .unity-websocket/uw go create "Enemy" && \
cd <unity-project-root> && node .unity-websocket/uw tf set-position "Enemy" "10,0,5" && \
cd <unity-project-root> && node .unity-websocket/uw tf set-rotation "Enemy" "0,45,0"

Load scene and activate GameObject:

cd <unity-project-root> && node .unity-websocket/uw scene load "Level1" && \
cd <unity-project-root> && node .unity-websocket/uw go set-active "Boss" true

Batch GameObject creation:

for i in {1..10}; do
  cd <unity-project-root> && node .unity-websocket/uw go create "Cube_$i" && \
  cd <unity-project-root> && node .unity-websocket/uw tf set-position "Cube_$i" "$i,0,0"
done

Wait for compilation then execute:

# Make code changes, then wait for compilation to finish
cd <unity-project-root> && node .unity-websocket/uw wait compile && \
cd <unity-project-root> && node .unity-websocket/uw editor refresh

Chain multiple commands sequentially:

# Execute commands from JSON file
cd <unity-project-root> && node .unity-websocket/uw chain execute commands.json

# Execute commands inline
cd <unity-project-root> && node .unity-websocket/uw chain exec \
  "GameObject.Create:name=Player" \
  "GameObject.SetActive:instanceId=123,active=true"

# Continue execution even if some commands fail
cd <unity-project-root> && node .unity-websocket/uw chain exec \
  "Editor.Refresh" \
  "GameObject.Find:path=InvalidPath" \
  "Console.Clear" \
  --continue-on-error

CI/CD Pipeline workflow:

#!/bin/bash
cd /path/to/unity/project

# Cleanup
node .unity-websocket/uw.js chain exec "Console.Clear" "Editor.Refresh"

# Wait for compilation
node .unity-websocket/uw.js wait compile

# Run tests (example)
node .unity-websocket/uw.js chain exec \
  "Scene.Load:name=TestScene" \
  "GameObject.Find:path=TestRunner" \
  "Console.Clear"

Best Practices

1. Always Verify Connection

   • Run cd <unity-project-root> && node .unity-websocket/uw status before executing commands
   • Ensure Unity Editor is running and server component is active

2. Use Hierarchical Paths

   • Prefer full paths for nested GameObjects: "Environment/Terrain/Trees"
   • Avoids ambiguity when multiple GameObjects share the same name

3. Monitor Console Logs

   • Use cd <unity-project-root> && node .unity-websocket/uw console logs --errors-only to catch errors during automation
   • Clear console before running automation scripts for clean logs

4. Batch Operations Carefully

   • Add delays between commands if creating many GameObjects
   • Consider Unity Editor performance limitations

5. Connection Management

   • Unity Editor Toolkit uses localhost-only connections (127.0.0.1)
   • Port range limited to 9500-9600 to avoid conflicts with other tools

6. Error Handling

   • Commands return JSON-RPC error responses for invalid operations
   • Check exit codes and error messages in automation scripts

7. Port Management

   • Default port 9500 works for most projects
   • Use --port flag if running multiple Unity Editor instances
   • Plugin avoids conflicts with Browser Pilot (9222-9322) and Blender Toolkit (9400-9500)

8. Wait Commands Usage

   • Use wait compile after making code changes to ensure compilation finishes
   • Use wait playmode enter/exit for play mode synchronization in automated tests
   • Use wait sleep to add delays between commands when needed
   • Note: Wait commands have delayed responses (default 5-minute timeout)
   • Domain reload automatically cancels all pending wait requests

9. Chain Commands Best Practices

   • Use chain for sequential command execution with automatic error handling
   • Default behavior: stop on first error (use --continue-on-error to override)

• Phase 2 (Current): 86 commands implemented across 15 categories
• Phase 3+: Animation, Physics, Lighting, Camera, Audio, Navigation - 400+ commands planned
• See full roadmap in COMMANDS.md
