# CLI Compatibility Layer

SkillHub provides a ClawHub CLI protocol compatibility layer for seamless migration of existing tools.

## Configuring ClawHub CLI

To connect ClawHub CLI to your SkillHub instance, configure the following environment variables:

### Environment Variable Configuration

**Linux/macOS (bash/zsh):**
```bash
# ~/.bashrc or ~/.zshrc
export CLAWHUB_SITE=https://skill.xfyun.cn
export CLAWHUB_REGISTRY=https://skill.xfyun.cn
```

**Windows (PowerShell):**
```powershell
# Permanent setting (current user)
[Environment]::SetEnvironmentVariable('CLAWHUB_SITE', 'https://skill.xfyun.cn', 'User')
[Environment]::SetEnvironmentVariable('CLAWHUB_REGISTRY', 'https://skill.xfyun.cn', 'User')

# Or temporary setting (current session)
$env:CLAWHUB_SITE = 'https://skill.xfyun.cn'
$env:CLAWHUB_REGISTRY = 'https://skill.xfyun.cn'
```

### Using CLI Flags (Single Command)

```bash
clawhub --site https://skill.xfyun.cn --registry https://skill.xfyun.cn install <skill>
```
