Google Agents Cli Adk Code

This is your reference when you're actually writing ADK agent code in Python, not scaffolding or deploying. It covers the practical stuff: defining agents with models and instructions, creating FunctionTools, wiring up callbacks for state management, and importing ADK's built-in tools correctly. One smart choice here is the explicit warning about ADK 2.0's Workflow API, which gates experimental graph-based orchestration behind user opt-in since it's pre-GA and needs Python 3.11+. The skill also includes a clever gatekeeper that checks for an existing project before letting you write code, and a helpful debug command for dealing with Gemini 404 errors caused by region misconfigurations. Works best alongside the workflow and scaffold skills from the same suite.
