 - The `anthropic` provider will only allow requests with a User-Agent that match Lacuna's built-in `claude-code` pattern.
 - The `anthropic` provider may only be used with models that match the `claude-*` glob pattern.
 
+`capability.models` maps each model glob pattern to a settings object with an optional `rewrite`:
+- `{}` ⇒ the model is allowed and forwarded as-is.
+- `{ "rewrite": "<target>" }` ⇒ the model is allowed and the upstream is called with `<target>` instead. In the example, requests for `us.anthropic.claude-opus-4-5*` are sent to Bedrock as the configured application-inference-profile ARN.
+
 Notes:
+- An empty or omitted `models` allows all models (no rewrite).
 - Built-in User-Agent patterns can be found in [src/user_agent.rs](src/user_agent.rs).
