The Agent Development Kit (ADK) by Google is a Go-based framework designed for creating and managing AI agents. It emphasizes a code-first approach, allowing developers to define agent logic and workflows directly in Go. This toolkit is flexible and modular, accommodating a wide range of applications from simple tasks to complex systems. While it's optimized for Gemini, ADK remains model-agnostic and can work alongside other frameworks, making it versatile for various use cases. Developers benefit from Go's strengths in concurrency and performance, which are essential for building cloud-native agent applications. The ADK supports a rich ecosystem of tools, enabling users to integrate pre-built functions or create custom ones, enhancing the agents' capabilities. Its modular structure allows for the composition of multiple specialized agents, fostering scalability in application development. Deployment is straightforward with ADK, as it facilitates easy containerization and supports cloud-native environments like Google Cloud Run. To add this toolkit to a project, developers simply run the command `go get google.golang.org/adk`.
