Challenges in deploying AI agents efficiently while maintaining performance and security.

Goals:

To build reliable AI agents using familiar tools and languages.
To enhance existing services with AI capabilities without significant rework.
To leverage Go’s concurrency and strong typing in AI applications.

Interests:

Open-source frameworks and tools.
Best practices in AI development and deployment.
Integration of AI with cloud services and existing infrastructure.

Communication Preferences:

Technical documentation and tutorials.
Community forums and GitHub repositories for collaboration.
Webinars and online workshops for hands-on learning.

Overview of the Agent Development Kit (ADK)

Google’s ADK for Go enables developers to create AI agents within their existing Go services. This toolkit allows developers to express agent logic, orchestration, and tool use directly in Go code, facilitating a smoother transition to production environments using Vertex AI Agent Builder and Agent Engine.

Key Features of the Agent Development Kit

The ADK provides:

A code-first programming model where agent behavior, tools, and orchestration are defined in standard source files.
Workflow agents that support sequential, parallel, and loop-style control flow.
A rich tool ecosystem, including built-in tools, custom function tools, OpenAPI tools, and Google Cloud tools.
Flexible deployment options, covering local runs, containers, Cloud Run, and Vertex AI Agent Engine.
Integrated evaluation and safety patterns with Vertex AI Agent Builder.

What ADK for Go Adds

The Go version of ADK maintains the core feature set of its Python and Java counterparts while providing an idiomatic Go API. Key points include:

Installation via go get google.golang.org/adk.
Open-source project hosted at github.com/google/adk-go.
Support for building, evaluating, and deploying sophisticated AI agents with flexibility and control.
Consistent abstractions for agents, tools, and workflows across all ADK languages.

A2A Protocol Support in Go

ADK for Go includes native support for the Agent2Agent (A2A) protocol, allowing agents to communicate securely. This enables a primary agent to orchestrate tasks among specialized sub-agents, which can operate locally or remotely.

MCP Toolbox for Databases and Tooling

The ADK Go features integration with the MCP Toolbox for Databases, supporting over 30 databases. This toolbox simplifies database operations by exposing them as tools, ensuring safe, predefined actions for agents.

Integration with Vertex AI Agent Builder and Agent Engine

ADK serves as the primary framework in Vertex AI Agent Builder for developing multi-agent systems. The workflow includes:

Local development using ADK, including ADK for Go.
Testing agents with multiple tools through the ADK quickstart and development UI.
Deployment to Vertex AI Agent Engine as a managed runtime.

Conclusion

The launch of ADK for Go positions it as a valuable tool for Go developers looking to build production-ready AI agents. By leveraging the same open-source framework as Python and Java, ADK for Go enhances the integration of AI capabilities into existing services while maintaining a consistent development experience.
