CrewAI - Agent observability or callbacks

[nethi]

I am trying to build a general purpose multi-agent chat UI for frameworks like CrewAI, AutoGen etc. While I have good progress made with AutoGen, I am struggling to get information on agent callbacks with CrewAI. I am looking at step_callbacks but the argument seems to be AgentAction class which doesn't have any info on which agent it is meant for. Whereas, task callbacks have TaskOutput argument that clearly indicates task that generated the output and the agent it belongs to etc.

It looks like callbacks argument on Agents is removed with some recent changes.

I looked at Phoenix and Langtrace implementations to see how they are instrumenting for crewAI observability - they all seem to monkey patch crewAI to get their job done.

I am wondering shouldn't there be first class support in crewAI for this ?
