Function/Tool Calling for Agents

Summary

Giving an agent a defined set of callable tools (search, calculator, database query, API calls) it can invoke to accomplish tasks beyond pure text generation.

• 1Give an agent 2-3 real tools and observe how it decides which to call and when.
• 2Learn to write clear tool descriptions — the agent's tool selection is only as good as the description.
• 3Practice handling tool failures gracefully so the agent doesn't get stuck in a loop.
