Here is a tool with reasoning capabilities to allow agents to search and analyze information from a knowledge base.
1. Run: `uv pip install openai agno lancedb sqlalchemy` to install the dependencies
2. Export your OPENAI_API_KEY
3. Run: `cookbook/92_models/dashscope/knowledge_tools.py` to run the agent
