- Shared base and layering rules: [`../inference/AGENTS.md`](../inference/AGENTS.md)
- This crate owns Chat Completions call orchestration. Payloads belong in `litellm-llms-types`, transformations in `llms/src/base_llm/chat` and `llms/src/<provider>/chat`
- Chat Completions is currently non-streaming: the route returns its completed response, cached through `litellm_inference::caching::execute_unary`
