 The `Assistant` class handles the [assistant messaging experience](/ai/developing-agents) (`assistant_view`), in which agent conversations happen in separate Chat and History tabs. Apps going forward use the agent messaging experience (`agent_view`) by default, where conversations happen in the Messages tab and you handle events such as [`app_home_opened`](/reference/events/app_home_opened) and [`message.im`](/reference/events/message.im) directly. Refer to [Adding agent features](/tools/bolt-python/concepts/adding-agent-features) and the [agent messaging experience changelog entry](/changelog/2026/06/30/agent-messages-tab) for the default experience and migration guidance.
