Building open source local agents for increased functionality with ollama

I am making agents such as search(optimised with rag), medicine search, math solver, weather etc with completely open source APIs that don't collect your data and they can be paired with ollama port so that your local llm will be able to use them from your terminal only and absolutely none of your data is transferred. Would you even use such a python package with variety of tools paired with ollama? What tools you would want to see in such a thing? I tested it with qwen3:4b and it works fine but you have to explicitly mention the tools to use sometimes.
