The tutorial covers the concept of tool/function calling in LLMs, setting up Ollama with gemma4:e2b, and implementing four real-world tools in Python (weather, news, time, currency conversion) using only standard library dependencies. The agent is tested with multi-tool queries, demonstrating reliable structured JSON output and function dispatch entirely offline on consumer hardware. ## Full article daily.dev links to this article rather than hosting it.
