fix: supporting the langchain output format!

[amindadgar]

it's now string and not crewai output!

Summary by CodeRabbit

• Bug Fixes
  • Improved handling of output types to ensure final answers are correctly extracted when the output is a string.

Walkthrough

The logic in tasks/agent.py was updated to check if crew_output is a string instead of an instance of CrewOutput. The assignment of final_answer was also updated to directly use crew_output as a string, with fallback logic left unchanged.

Changes

File(s)	Change Summary
tasks/agent.py	Changed type check from CrewOutput to str for crew_output and updated assignment logic.

Poem

A string or not, the agent thought,
CrewOutput’s cloak is now forgot.
With simpler checks, the code runs light,
The answer’s clear, the logic tight.
Hop along, dear code, don’t lag behind—
The rabbit’s path is well-defined! 🐇

8-8: Remove unused import.

The CrewOutput import is no longer used after the logic change to handle string outputs directly.

20-23: Update documentation to reflect the new output format.

The function docstring still references "Crew.ai Flow" terminology, but the implementation now expects string outputs to support langchain format. Consider updating the documentation to reflect this change.

119-120: Confirm kickoff_async() return type & clean up unused import

• I did not find a local async def kickoff_async in tasks/hivemind/agent.py (line 26) or elsewhere in the repo, so it’s likely inherited from the Flow base class in the CrewAI SDK. Please verify that your current CrewAI version returns a Python str (not a CrewOutput) from kickoff_async().
• Remove the now-unused CrewOutput import in tasks/agent.py (line 8).
• Update any docstrings or logging around crew_output (e.g., line 114) to reflect that it’s a str rather than a CrewOutput object.
