Hello 🙂

I managed to set up a functional environment with crewai and ollama (running the template works correctly). My goal is to set up a crew that modifies code directly in a directory. For now, I just want the crew to add all missing docstrings in the code or update the existing ones. But I don’t know how to make the crew update each file. I succeeded in outputting a “smell\_code\_report.md”.

I tried using the tools `DirectoryReadTool`, `FileReadTool`, and `FileWriterTool` without success.

Could someone indicate how to get the crew to modify the files?

Is it necessary to create dynamic tasks? For example, a task that takes a Python file as input and modifies it? Or perhaps, write the path with the same name but in a different directory structure?

Thank you !
