Greptile Summary

Documents the OpenRouter API base environment variable needed to route Strix requests through OpenRouter.

• Adds LLM_API_BASE=https://openrouter.ai/api/v1 to the OpenRouter setup example.

Confidence Score: 5/5

The documentation-only change appears safe to merge.

The added environment variable is consistent with the documented provider-routing configuration, and no incorrect or unsafe behavior was identified.
