+- Anthropic Claude 4.6 models default to `adaptive` thinking in OpenClaw when no explicit thinking level is set.
+- You can override per-message (`/think:<level>`) or in model params:
+  `agents.defaults.models["anthropic/<model>"].params.thinking`.

 ## Prompt caching (Anthropic API)
 
 OpenClaw supports Anthropic's prompt caching feature. This is **API-only**; subscription auth does not honor cache settings.
