 ## Best practices
 
+Starting with Copilot SDK v0.1.28, permission handling is opt-in. If a session may need tool, file, or system access, set `OnPermissionRequest` explicitly when creating it.
+
 1. **Always clean up**: Use try-finally or `await using` to ensure `StopAsync()` is called
 2. **Handle connection errors**: The CLI might not be installed or running
 3. **Set appropriate timeouts**: Use `CancellationToken` for long-running requests
