Unity Skills (official)
Unity's own collection of skills for AI coding agents: prompts, slash commands and tools built for Unity workflows.
Listed from the author's README. GameSkill has not run this end to end yet. Agent support and install steps are as documented by the author.
Install
npx skills add Unity-Technologies/skills --skill create-2d-physicsInstalls only this skill. Add -a claude-code (puts it in .claude/skills/), -a codex or -a cursor (.agents/skills/) to choose the agent, and -g to install it for your user instead of the project.
Commands are copied from the project's README. Check the repository before running anything on your machine.
Install for a specific agent
| Agents | -a | Folder |
|---|---|---|
| Claude Code | claude-code | .claude/skills/ |
| Codex | codex | .agents/skills/ |
| Cursor | cursor | .agents/skills/ |
| Gemini CLI | gemini-cli | .agents/skills/ |
| GitHub Copilot | github-copilot | .agents/skills/ |
| OpenCode | opencode | .agents/skills/ |
| Windsurf | windsurf | .windsurf/skills/ |
Add -a <flag> to the command. These are project folders; add -g to install for your user account instead.
What you get
- Bundled 1 supporting file and 2 reference docs the agent reads when needed
Good fit
- Any Unity 2D physics question, in 2D Physics Core or the legacy Rigidbody 2D system

What's inside
- Which physics system
- System reference
- Worked examples
Good to know
Maintained and published by Unity. Many skills drive the open Unity Editor through the Unity CLI instead of editing scene files by hand.
Requirements
- A Unity project
- Unity CLI (recommended: many skills drive the open Editor through it)
