## What it does

This skill wraps a command set for s&box by Facepunch Studios. It works directly with scene (`.scene`), prefab (`.prefab`), material (`.vmat`), sound (`.sound`), and config JSON files. Commands are grouped by function: project management, scene editing, prefab work, C# code generation, input setup, and collision layers. Most operations don't require the editor to be running.

You'll need Python 3.10+ and s&box installed via Steam—the path is auto-detected or set via `SBOX_PATH`. The code generator produces components, resources, Razor UI panels, and editor menus. It also supports asset graph queries, file diffs, object filtering by tags or name, and bulk modifications.

Key constraint: the skill manipulates project files and needs a properly configured s&box and Python environment. Always pass `--json` when running commands for agent use.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add HKUDS/CLI-Anything --skill cli-anything-sbox -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add HKUDS/CLI-Anything --skill cli-anything-sbox -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add HKUDS/CLI-Anything --skill cli-anything-sbox -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install HKUDS/CLI-Anything cli-anything-sbox
```

2. **Manually: put the files in place**
- File: `.github/skills/cli-anything-sbox/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add HKUDS/CLI-Anything --skill cli-anything-sbox -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/HKUDS/CLI-Anything --path skills/cli-anything-sbox
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add HKUDS/CLI-Anything --skill cli-anything-sbox -a opencode
```

## When to use it
- Create a new scene with objects and components without opening the editor
- Generate a C# component with specific methods and properties
- Find all objects in a scene by tag or name and modify them at once
- Convert a scene object into a reusable prefab
- Validate your project for broken asset refs, duplicate GUIDs, and malformed configs

## Example prompts
- Create a new scene level_1 in Assets/scenes, add an Enemy object with rigidbody and box_collider components at position 100,0,0
- Generate a C# Tower component with properties Damage (float, 25) and Range (float, 500), add OnUpdate and OnFixedUpdate methods
- Find all objects tagged tower in the scene, move them to 0,0,100, and enable them

# s&box CLI

Agent-native CLI for the s&box game engine (Facepunch Studios, Source 2). 79+ commands across 14 groups. Manipulate `.scene`, `.prefab`, `.vmat`, `.sound`, `Input.config`, `Collision.config` JSON files directly, generate idiomatic C# components, and run a real-time asset graph over the project.

## Installation

```bash
pip install git+https://github.com/HKUDS/CLI-Anything.git#subdirectory=sbox/agent-harness
```

## Requirements

- Python 3.10+
- s&box installed via Steam - auto-detected, or set `SBOX_PATH` to a custom installation directory.
- Most commands work entirely on the project's JSON files - s&box does not need to be running.

## Global Options

```
--json          Machine-readable JSON output (always pass for agent use)
--project PATH  Project directory (auto-detects from cwd .sbproj if omitted)
```

## Command Groups

### project - Manage s&box projects

```bash
cli-anything-sbox project new --name MyGame --output-dir ./MyGame
cli-anything-sbox --json project info
cli-anything-sbox project config --max-players 32 --tick-rate 64
cli-anything-sbox --json --project ./MyGame project add-package facepunch.libsdf
cli-anything-sbox --json --project ./MyGame project remove-package facepunch.libsdf
# Lint: broken asset refs, duplicate GUIDs, malformed Input.config
cli-anything-sbox --json --project ./MyGame project validate
cli-anything-sbox --project ./MyGame project validate --no-inputs --no-guids
```

### scene - Manipulate `.scene` files

```bash
cli-anything-sbox scene new --name gameplay -o ./Assets/scenes/gameplay.scene
cli-anything-sbox --json scene info ./scene.scene
cli-anything-sbox --json scene list ./scene.scene
cli-anything-sbox scene add-object ./scene.scene Enemy --position "100,0,0" --components "model,box_collider,rigidbody" --tags "enemy"
cli-anything-sbox scene remove-object ./scene.scene --name Enemy
cli-anything-sbox scene add-component ./scene.scene <object-guid> Sandbox.PointLight
cli-anything-sbox scene remove-component ./scene.scene <object-guid> --component-type Sandbox.Rigidbody
cli-anything-sbox --json scene modify-object ./scene.scene --guid <guid> --name NewName --position "200,0,0"
cli-anything-sbox --json scene clone-object ./scene.scene --name Enemy --new-name EnemyCopy --position "300,0,0"
