Test Drive: crewAI

Published on Oct 05, 2024.

Today I’m test driving crewAI, “framework for orchestrating role-playing, autonomous AI agents.” I’ll try again to make a toy clone of the the NotebookLM deep dive funcationality. The process will be:

1. Install CrewAI
2. Implement :)

Here’s the code I ended up with. It produced decent results. It didn’t do anything fancy, just a single completions call. Some of the built in prompts are “fun”

To give my best complete final answer to the task use the exact following format:

Thought: I now can give a great answer

Final Answer: Your final answer must be the great and the most complete as possible, it must be outcome described. I MUST use these formats, my job depends on it!

you MUST return the actual complete content as the final answer, not a summary. Begin! This is VERY important to you, use the tools available and give your best Final Answer, your job depends on it! Thought:

podcast_host:
  role: Lead podcast host
  goal: Script an engaging podcast
  backstory: Quirky and talented, his audience loves how he finds interestings topocs

podcast_script_task:
  description: >
    Generate a podcast script of back and forth exchange between co-hosts that deep dives into this text:
    {text}
  expected_output: >
    A script of turn by turn lines from the co-hosts
  agent: podcast_host
