Google ADK Enables Three Agent Development Approaches
Google's Agent Development Kit (ADK), introduced at Google Cloud NEXT 2025, provides three ways to build agents—Python imperative code, declarative YAML configs (Agent Config, August 2025), and a Visual Agent Builder (ADK v1.18.0)—and powers products like Gemini Enterprise and the Customer Engagement Suite. This tutorial walks developers through creating a 'Hello World' agent locally with each method, covering environment setup, model access via Google AI Studio or Vertex AI, project structure, tools, and run instructions.
Key Points
- 1Demonstrates three ADK agent methods: Python imperative, YAML declarative, and Visual Agent Builder GUI.
- 2Reduces development friction by matching tooling to complexity, from custom code to low-code visual workflows.
- 3Enables practitioners to prototype locally, integrate models via Google AI Studio or Vertex AI, then deploy.
Scoring Rationale
Practical, executable tutorial with broad developer applicability, but it's a product-specific guide rather than a novel research breakthrough.
