Building with Google's Agent Development Kit (ADK)

The agent loop you keep rewriting is already built, and ADK is Google's version of it. Building with Google's Agent Development Kit (ADK) takes the lid off that loop and builds production agents on top of it.

Across eleven parts it covers the loop itself, why tool descriptions make or break an agent, multi-agent teams, session state and memory, streaming so your user does not think it crashed, keeping sensitive instructions away from the model, growing an agent's powers in the order you will want them, long-running execution, stateful deployment, and catching silent regressions.
