Unity Skills (official)
Unity's own collection of skills for AI coding agents: prompts, slash commands and tools built for Unity workflows.
信息来自作者的 README。 GameSkill 还没完整跑过。支持的 Agent 和安装步骤以作者文档为准。
安装
npx skills add Unity-Technologies/skills --skill physics-3d-collisionInstalls 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.
命令照搬项目 README。在本机运行前，请先看一眼仓库。
为指定 Agent 安装
| Agent | -a | 文件夹 |
|---|---|---|
| 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/ |
在命令后加 -a <参数>。以上是项目级文件夹；加 -g 则安装到你的用户目录。
包含内容
- Worked steps: Identify Your Symptom; Collision Callback Checklist
- A verification step before the work is called done
- Bundled 1 reference doc and 1 supporting file the agent reads when needed
适合
- OnCollisionEnter or OnTriggerEnter doesn't fire, objects pass through each other, raycasts miss, or a MeshCollider misbehaves

OnTriggerEnter never fires on my pickup. Find out why.关于这个 Skill
Diagnoses 3D PhysX collision and trigger problems. Use when OnCollisionEnter or OnTriggerEnter doesn't fire, objects pass through each other, raycasts miss, or a MeshCollider misbehaves. Also answers 2D and DOTS physics best-effort if no dedicated skill is available.
From the physics-3d-collision SKILL.md in Unity-Technologies/skills.
What's inside
- CRITICAL FACT (read first, do not override)
- Required Output -- non-negotiable
- STOP CHECK -- match before any tool call
- Fast-Path 1 -- 2D physics (best-effort, outside primary scope)
- Fast-Path 2 -- DOTS / ECS / Unity Physics package (best-effort, outside primary scope)
- Fast-Path 3 -- Two kinematic triggers not firing OnTriggerEnter
- Fast-Path 4 -- Ragdoll explodes on frame 1 with no applied forces
- Fast-Path 5 -- CharacterController + OnCollisionEnter not firing
- Fast-Path 6 -- AddForce stopped working after object settled
- Fast-Path 7 -- All physics frozen but raycasts still work
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.
环境要求
- A Unity project
- Unity CLI (recommended: many skills drive the open Editor through it)
