+### Fixed
+- Fixed Assist pipeline crash during intent recognition on some Home Assistant versions:
+  - Replaced `conversation.IntentResponse` / `conversation.IntentResponseErrorCode` usage with `homeassistant.helpers.intent` equivalents in the OpenClaw conversation agent.
+  - Resolves `AttributeError: module 'homeassistant.components.conversation' has no attribute 'IntentResponse'`.
