+### Provider Architecture
+
+PicoClaw routes providers by protocol family:
+
+- OpenAI-compatible protocol: OpenRouter, OpenAI-compatible gateways, Groq, Zhipu, and vLLM-style endpoints.
+- Anthropic protocol: Claude-native API behavior.
+- Codex/OAuth path: OpenAI OAuth/token authentication route.
+
+This keeps the runtime lightweight while making new OpenAI-compatible backends mostly a config operation (`api_base` + `api_key`).
