unity-cli

A Claude Code / Claude skill that teaches Claude how to drive Unity from the command line using Unity's official unity CLI.

With this skill installed, Claude can:

• Inspect installed Unity editors, Hub-registered projects, and live Editor instances (unity editors -i, unity projects list, unity status)
• Create and open Unity projects (unity projects new/create/open)
• Run headless CI builds for any platform (Android, iOS, WebGL, Standalone, etc.) via unity build
• Run EditMode/PlayMode tests and summarize the resulting NUnit report
• Run arbitrary batch-mode Editor commands via unity run
• Install Unity editors and modules (with dry-run/confirmation guardrails before large downloads)
• Talk to an already-running Unity Editor live, through the Unity Pipeline package (unity list / unity command / unity status) or via MCP (unity mcp configure) — note that this live surface commonly includes arbitrary-code-execution (an eval-style command), not just narrow scene/GameObject accessors. SKILL.md has the details on scope, argument conventions, and when to confirm with the user before running a mutating command.

Install

Copy this repository into your Claude skills directory (or git clone it there directly).

macOS/Linux (bash/zsh):

git clone https://github.com/digital8150/UnityCLI-Skill.git ~/.claude/skills/unity-cli

Windows (PowerShell or cmd): ~ is not expanded by git.exe outside of a POSIX shell — passing it literally creates a folder named ~ instead of resolving to your home directory. Use the full path instead:

git clone https://github.com/digital8150/UnityCLI-Skill.git "$env:USERPROFILE\.claude\skills\unity-cli"

Requires the unity CLI to already be installed and on PATH.
