## Plugin

The plugin allows users to rewrite Claude Code prompt and custom router. The plugin path is in `$HOME/.claude-code-router/plugins`. Currently, there are two demos available: 
1. [custom router](https://github.com/musistudio/claude-code-router/blob/dev/custom-prompt/plugins/deepseek.js)
2. [rewrite prompt](https://github.com/musistudio/claude-code-router/blob/dev/custom-prompt/plugins/gemini.js)

You need to move them to the `$HOME/.claude-code-router/plugins` directory and configure 'usePlugin' in `$HOME/.claude-code-router/config.json`，like this:

```json
{
    "usePlugin": "gemini",
    "LOG": true,
    "OPENAI_API_KEY": "",
    "OPENAI_BASE_URL": "",
    "OPENAI_MODEL": ""
}
```
