Chapter 5: Knowledge, RAG, and Tools

Welcome to Chapter 5: Knowledge, RAG, and Tools. In this part of Agno Tutorial: Multi-Agent Systems That Learn Over Time, you will build an intuitive mental model first, then move into concrete implementation details and practical production tradeoffs.

Agno agents combine tool execution and knowledge retrieval to produce grounded, high-utility outputs.

Augmentation Surfaces

Surface Value
vector/RAG retrieval domain grounding
toolkits external action and system interaction
guardrails safe execution boundaries

Operational Rules

  • treat tool calls as policy-governed actions
  • track retrieval quality and stale context rates
  • ensure typed contracts for tool inputs/outputs

Source References

Summary

You now understand how to combine knowledge and tool layers in Agno without sacrificing reliability.

Source Code Walkthrough

libs/agno/agno/knowledge/ and libs/agno/agno/tools/

Knowledge and RAG capabilities live in libs/agno/agno/knowledge/, while tool integrations are in libs/agno/agno/tools/. The AgnoKnowledge base class shows how documents are chunked, embedded, and searched. Browsing the tools directory reveals how Agno wraps external APIs and services as callable tools for agents.
