What this skill does

# 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 ./MyGame project add-package facepunch.libsdf
cli-anything-sbox --json --project ./MyGame project remove-package facepunch.libsdf

cli-anything-sbox --json scene modify-component ./scene.scene <object-guid> <component-guid> --properties '{"Damage":50}'

# Find objects matching one or more filters (AND-combined)
cli-anything-sbox --json scene query ./scene.scene --has-component rigidbody --has-tag tower
cli-anything-sbox --json scene query ./scene.scene --name-regex "^Tower\d$" --in-bounds "0,-500,-50,1000,500,50"

# Extract every asset reference (.vmdl, .vmat, .vsnd, .vtex, .vpcf, .prefab) from a scene
cli-anything-sbox --json scene refs ./scene.scene

# Apply the same modification to every object that matches a query
cli-anything-sbox --json scene bulk-modify ./scene.scene --has-tag tower --position "0,0,100" --enable

# Structural diff between two scenes (added/removed/modified GameObjects + SceneProperties)
cli-anything-sbox --json scene diff ./old.scene ./new.scene

# Insert a prefab as a GameObject in a scene
cli-anything-sbox --json scene instantiate-prefab ./level.scene ./Assets/prefabs/bullet.prefab --position "10,0,0"
```

### prefab - Manage `.prefab` files

```bash
cli-anything-sbox prefab new --name Bullet -o ./Assets/prefabs/bullet.prefab --components "model,sphere_collider,rigidbody"
cli-anything-sbox --json prefab info ./Assets/prefabs/bullet.prefab

cli-anything-sbox --json prefab add-component ./prefab.prefab rigidbody
cli-anything-sbox prefab remove-component ./prefab.prefab --component-type Sandbox.Rigidbody
cli-anything-sbox --json prefab list

# Asset references inside a prefab
cli-anything-sbox --json prefab refs ./prefab.prefab

# Modify component properties on a prefab (by component type or component GUID)
cli-anything-sbox --json prefab modify-component ./prefab.prefab --component-type Sandbox.Rigidbody --properties '{"Gravity":false,"MassOverride":50}'

# Structural diff between two prefabs (root + named children)
cli-anything-sbox --json prefab diff ./old.prefab ./new.prefab
```

### codegen - Generate C# code

```bash
# Plain Component
cli-anything-sbox codegen component --name PlayerController --methods OnUpdate,OnFixedUpdate -o ./Code/PlayerController.cs

# Component with [Property] fields

# Static or base-derived class
cli-anything-sbox codegen class --name Math2 --static -o ./Code/Math2.cs

# PanelComponent + sibling ScreenPanel scaffold (handles the s&box quirk where
# PanelComponent input only works when both are on the same GameObject).
# Emits .razor + .razor.scss + a paste-ready GameObject snippet, or appends
# directly to a scene with --scene.
cli-anything-sbox --json codegen panel-component --name HudBar -o ./UI/HudBar.razor
cli-anything-sbox codegen panel-component --name Crosshair -o ./UI/Crosshair.razor --scene ./Assets/scenes/game.scene
