Unity Skill

Control Unity Editor via OpenClaw Unity Plugin. Use for Unity game development tasks including scene management, GameObject/Component manipulation, debugging, input simulation, and Play mode control. Triggers on Unity-related requests like inspecting scenes, creating objects, taking screenshots, testing gameplay, or controlling the Editor.

Security Scan

The skill's files, install step, and runtime instructions are consistent with a Unity Editor remote-control plugin — it asks for no unrelated credentials and installs only a local gateway extension — but it exposes powerful editor APIs (script execution, file reads, package installs) that should be treated as high-privilege and used with care.

Purpose & Capability

Name/description (control Unity Editor) match the provided files and instructions: the repository contains a gateway extension (extension/index.ts), an install script to copy that extension into ~/.openclaw/extensions/unity, and extensive tool documentation for scene/GameObject/component manipulation and Play-mode control. No unrelated binaries, credentials, or config paths are requested.

Instruction Scope

SKILL.md stays on-scope for remote Unity editor control and documents how to install and use the gateway/MCP modes. However the tool set includes 'script.execute' (reflection-based method calls), 'script.read' (read script files), asset deletion/move, and package.add (including git URLs). Those capabilities legitimately belong to a remote-control Unity skill, but they are high-privilege: they can read project source, run arbitrary code in the Editor context, install code from remote git repositories, and capture screenshots. SKILL.md also describes remote Gateway usage (Telegram/Discord/OpenClaw channels) where results could be transmitted off-machine — this is expected but increases the need for caution.

Install Mechanism

There is no external network fetch during install: install-extension.sh copies extension files from the skill directory into ~/.openclaw/extensions/unity. No downloads from unknown URLs or archive extraction are performed. This is a low-risk local file copy install.

Credentials

The skill declares no required environment variables, no primary credential, and no external config paths. The lack of requested secrets is proportional to the stated purpose. Note: the extension enables HTTP endpoints and sets CORS headers (Access-Control-Allow-Origin: *), which is functional for gateway usage but can broaden what origins may interact with the local handler if the gateway exposes it.

Persistence & Privilege

The skill does not request 'always: true' and SKILL.md advertises disableModelInvocation: true (preventing autonomous tool calls by default). The install copies files into the user's OpenClaw extensions folder (expected). The extension does not appear to modify other skills' configs or request system-wide privileges.

Assessment

This skill appears coherent for remote control of the Unity Editor, but it grants powerful capabilities inside your Editor/project (reading script files, executing arbitrary code via reflection, installing packages from git, deleting/moving assets, taking screenshots). Before installing: 1) Backup your project and test in a disposable project first. 2) Review extension/index.ts yourself (it will be copied to ~/.openclaw/extensions/unity). 3) Keep disableModelInvocation set to true unless you explicitly trust the remote gateway and want the agent to auto-call tools. 4) If you will use the Gateway (Telegram/Discord/OpenClaw channels), be aware results (console output, screenshots, script contents) can be relayed to remote channels — only enable remote access when you trust the channel/recipients. 5) If you do not want the skill to install code from external git URLs, avoid using the package.add with gitUrl option or disable the Bridge in environments where network-sourced packages are risky. 6) If you need higher assurance, review or run the extension in a restricted environment (no network access) and audit any added packages before accepting them.

Unity Plugin Skill

Control Unity Editor through ~100 built-in tools. Works in both Editor and Play mode.

Connection Modes

1. OpenClaw Gateway (Remote)

For Telegram, Discord, and other OpenClaw channels:

• Auto-connects when Unity opens
• Configure in: Window → OpenClaw Plugin → Settings

2. MCP Bridge (Local)

For Claude Code, Cursor, and local AI tools:

• Start: Window → OpenClaw Plugin → MCP Bridge → Start
• Default port: 27182
• Add to Claude Code: claude mcp add unity -- node <path>/MCP~/index.js

First-Time Setup

If unity_execute tool is not available, install the gateway extension:

# From skill directory
./scripts/install-extension.sh

# Restart gateway
openclaw gateway restart

The extension files are in extension/ directory.

What install-extension.sh Does

# 1. Copies extension files from skill to gateway
#    Source: <skill>/extension/
#    Destination: ~/.openclaw/extensions/unity/

# 2. Files installed:
#    - index.ts     # Extension entry point (HTTP handlers, tools)
#    - package.json # Extension metadata

# After installation, restart gateway to load the extension.

unity://editor/state	Editor state
unity://console/logs	Console logs
unity://session/info	Session info

Tips

Screenshot Modes

• Play mode: ScreenCapture - includes all UI overlays
• Editor mode: Camera.main.Render() - no overlay UI
• Use {method: "camera"} for camera-only capture

Finding Objects

gameobject.find {name: "Player"}           # By exact name
gameobject.find {tag: "Enemy"}             # By tag
gameobject.find {componentType: "Camera"}  # By component
gameobject.getAll {activeOnly: true}       # All active objects

Script Recompilation

Unity may not auto-recompile after code changes. Use:

editor.refresh    # Full asset refresh + recompile

Play Mode Transitions

• Plugin survives Play mode transitions via SessionState
• If connection lost, wait for auto-reconnect or use Window → OpenClaw Plugin → Settings → Connect

MCP Bridge Usage

For Claude Code / Cursor integration:

1. Start: Window → OpenClaw Plugin → MCP Bridge → Start
2. Register: claude mcp add unity -- node /path/to/MCP~/index.js
3. Verify: curl http://127.0.0.1:27182/status

Input Simulation Limitation

Keyboard/mouse simulation works for UI interactions but NOT for Input.GetKey(). For gameplay testing:

• Use transform.setPosition to move objects directly
• Or migrate to Unity's new Input System

Troubleshooting

Issue	Solution
Tool timeout	Check Unity is responding, try editor.getState
Gateway no connection	Check Window → OpenClaw Plugin → Settings
MCP no connection	Start MCP Bridge, verify port 27182
Scripts not updating	Use editor.refresh to force recompile
Wrong screenshot	Use Play mode for game view with UI
MCP 504 timeout	Unity busy or MCP Bridge not started
Test Runner not found	Install com.unity.test-framework package
