## What it does

The skill connects coding agents to an active Unity Editor over local server ports `7800-7849`. The agent modifies C# files, initiates domain reloads via `recompile`, and tracks compilation progress automatically. Setting `set_autotick` is necessary for headless background edits. Without it, unfocused Unity windows throttle execution loops.

In Play Mode or Mono development builds, developers can patch functions instantly using `reload_file`. Tagged methods swap logic without incurring full domain reloads. However, this runtime patching works solely on public `void` instance methods and fails entirely on IL2CPP builds. For batch scene manipulation, the tool uses `run_script` on external C# files to avoid messy multiline evaluation.

## Requirements
- Works with: Unity

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Unity-Technologies/skills --skill unity-pipeline -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/unity-pipeline/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/unity-pipeline/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Unity-Technologies/skills --skill unity-pipeline -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/unity-pipeline/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Unity-Technologies/skills --skill unity-pipeline -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/unity-pipeline/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Unity-Technologies/skills unity-pipeline
```

2. **Manually: put the files in place**
- File: `.github/skills/unity-pipeline/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Unity-Technologies/skills --skill unity-pipeline -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Unity-Technologies/skills --path skills/unity-pipeline
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/unity-pipeline/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Unity-Technologies/skills --skill unity-pipeline -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Unity-Technologies/skills/tree/HEAD/skills/unity-pipeline/SKILL.md

## When to use it
- execute Unity test fixtures from the command line
- patch gameplay logic without triggering domain reloads
- generate scene objects using standalone C# builders
- recompile assets while the editor runs in the background

## Example prompts
- Check Unity Editor connection status and enable autotick
- Run editor tests filtering by MyFixture.MyTest
- Execute builder script at AgentScripts/Build.cs with entry Build.All
