Google Gemini Agents Docs: Build Your First Agent

What this doc covers

Google's Gemini Agents documentation is the official entry point for agent development, covering the full path from 'what is an agent' to function calling and multi-step orchestration.

Learning path

1. Agent basics: Agent = model + tools + loop (perceive → decide → act). Understanding this loop matters more than any framework.
2. Function calling: expose business capabilities as structured functions; the model calls them on demand.
3. Multi-tool orchestration: tool selection, retries, and result integration.
4. Context management: strategies for growing context in the agent loop (summarize, trim, retrieve).

Practice tips

• Write a minimal single-tool agent by hand before adopting a framework.
• Write tool descriptions that state clearly when to use them — this drives call accuracy.
• Add logging and human checkpoints before automating.
