Use CrewAI BaseTool class #11

The errors you are getting with your crew are related to how you've defined BaseTool - it's actually something provided by the framework and formatted a little different from what you created here.

To create new tools for agents you can either subclass BaseTool (similar to what you've done now), or use the @tool decorator, both from CrewAI's pacakages.

1. Install crewai_tools with your package manager
2. Use from crewai_tools import BaseTool (and/or the tool decorator)

The documentation gives some examples on creating custom tools and the ai-agent-crew repo uses the @tool decorator, either way is acceptable.
