## External Service Detection Pattern

```python
def _detect_lm_studio() -> dict:
    """Detect LM Studio on localhost:1234."""
    import requests
    try:
        resp = requests.get("http://localhost:1234/v1/models", timeout=3)
        if resp.status_code == 200:
            return {"available": True, "models": [m["id"] for m in resp.json().get("data", [])]}
    except Exception:
        pass
    return {"available": False, "models": []}
```

This pattern works for any OpenAI-compatible local LLM server.
