Walkthrough

Changes

Cohort / File(s)	Summary
Agent Control Flow flo_ai/flo_ai/agent/agent.py	Removed branch in _run_with_tools that extracted text via get_message_content(response) and appended it as an assistant message when no explicit tool-content was present; now proceeds directly to tool execution without fallback text extraction.
Agent Configuration flo_ai/flo_ai/models/agent.py	Added import for MessageType; changed default value of act_as field in AgentConfigModel from None to MessageType.ASSISTANT.

11-11: LGTM! Import is necessary and correct.

The import of MessageType is appropriately added to support the new default value for the act_as field.

---

192-194: Approve the default value change.

Setting MessageType.ASSISTANT as the default for act_as is a safe change. The code already has fallback logic that gracefully handles None values (e.g., self.act_as if self.act_as is not None else MessageType.ASSISTANT), and the field remains Optional[str], so explicit None values are still supported. No agent configuration files in the repository depend on a None default.
