[feature request] CrewAI - add instrumentation for AgentAction to capture tool usage as separate attribute

[annguyenarize]

Tool usage is formatted within LLM span output as Action: {tool name} and requires additional parsing in order to evaluate. Adding instrumentation for AgentAction and capturing tool usage as separate attributes would make it easier to trace agent decisions.

hi @annguyenarize, thanks for filing the ticket.

Do you mind adding the current(existing) the desired version of the attributes in json format in addition to the screenshot? That'd be very helpful.

Thanks!

@caroger sure, see below. The agent_tools attribute on agent attributes was manually added to track which tools the agent called. Open to other formatting ideas - I just needed a way to grab the tools called without parsing the outputs in the LLM span attributes.

llm_attributes.json
