Is there any reason for choosing agent_uuid instead of agent_id?

Is there any reason for choosing agent_uuid instead of agent_id?

In the agent domain, we already have agent_id for the identifier returned by the Agent Controller, for example GAT-29::2d61a736. That is why using agent_id here may be confusing.

However, for consistency, I can change it to agent_id if you prefer.
