I would like to get detailed info from callback function of a crew

Well, the argument passed to the task_callback function is an object of the TaskOutput class. The attributes of this class are documented here.

As for the argument passed to the step_callback function, it will vary depending on the step that was completed. It can be an object of the ToolResult, AgentAction, or AgentFinish class. That’s why I suggested earlier that a well-defined event listener might be better suited for your use case.

In any case, to learn more about the argument your callback is receiving, here’s a snippet:

from crewai import LLM, Agent, Task, Crew, Process
from typing import Any

# [Define your Agents, Tasks, Tools, etc.]

def log_task_output(task_output: Any):
    print("\n--- Task Callback Received ---")
    if task_output is not None:
        print(f"Object type: {type(task_output).__name__}")
        attributes = getattr(
            task_output, "__dict__", "N/A (object may lack __dict__)"
        )
        print(f"Instance attributes: {attributes}")
    else:
        print("Received None object.")

def log_step_output(step_output: Any):
    print("\n--- Step Callback Received ---")
    if step_output is not None:
        print(f"Object type: {type(step_output).__name__}")
        attributes = getattr(
            step_output, "__dict__", "N/A (object may lack __dict__)"
        )
        print(f"Instance attributes: {attributes}")
    else:
        print("Received None object.")

my_crew = Crew(
    agents=[...],
    tasks=[...],
    process=Process.sequential,
    task_callback=log_task_output,
    step_callback=log_step_output,
    verbose=False
)

my_crew.kickoff()
