unity-package-management

An agent skill by Unity-Technologies, from Unity-Technologies/unity-agent-plugin. Tags: design, games, unity.

What it does

Use when adding, removing, upgrading, or discovering Unity (UPM) packages programmatically from outside the Editor — headless or CI package installs via the C# UnityEditor.PackageManager.Client API, verifying package ids/versions against the Unity registry, or choosing which packages a game needs by genre, platform, and monetization. The Unity CLI does not manage UPM packages, so this skill covers that gap. Triggers on "install a Unity package", "add com.unity.*", "set up packages headless/CI", "which packages for a [genre] game".

Install

With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:

npx skills add Unity-Technologies/unity-agent-plugin --skill unity-package-management

Or copy the skill folder into Claude Code's skills directory by hand (~/.claude/skills for every project, or .claude/skills inside one):

git clone --depth 1 https://github.com/Unity-Technologies/unity-agent-plugin
cp -r unity-agent-plugin/skills/unity-package-management ~/.claude/skills/unity-package-management
