Building Agents on Gemini
Google publishes practical advice for building agents with Gemini, from its developer blog to the open-source Agent Development Kit. The lessons echo the rest of this course: keep the design simple, give the agent good tools, and close the verification loop.
Start simple, add only when needed
It is tempting to reach for a heavy multi-agent framework on day one. Usually you do not need it. Start with a single agent and a few good tools. Add structure only when a real limitation forces you to, not because it feels sophisticated.
Tools are the leverage
An agent is only as capable as the tools it can call. Well-described tools with clear inputs and outputs let the model do real work. Vague or overlapping tools confuse it. Spend your effort there before you add more agents.
Frameworks are optional
Google's ADK and similar kits help when you need them, but the patterns matter more than any one framework. Learn the patterns and you can build on any stack.
