Agent Development Kit (ADK) for Go

License Go Doc Nightly Check r/agentdevelopmentkit View Code Wiki

An open-source, code-first Go toolkit for building, evaluating, and deploying sophisticated AI agents with flexibility and control.

Important Links: Docs & Samples & Python ADK & Java ADK & Kotlin ADK & TypeScript ADK & ADK Web.

Agent Development Kit (ADK) is a flexible and modular framework that applies software development principles to AI agent creation. It is designed to simplify building, deploying, and orchestrating agent workflows, from simple tasks to complex systems. While optimized for Gemini, ADK is model-agnostic, deployment-agnostic, and compatible with other frameworks.

This Go version of ADK is ideal for developers building cloud-native agent applications, leveraging Go's strengths in concurrency and performance.

✨ Key Features

  • Idiomatic Go: Designed to feel natural and leverage the power of Go.
  • Rich Tool Ecosystem: Utilize pre-built tools, custom functions, or integrate existing tools to give agents diverse capabilities.
  • Code-First Development: Define agent logic, tools, and orchestration directly in Go for ultimate flexibility, testability, and versioning.
  • Modular Multi-Agent Systems: Design scalable applications by composing multiple specialized agents.
  • Deploy Anywhere: Easily containerize and deploy agents, with strong support for cloud-native environments like Google Cloud Run.

🚀 Installation

To add ADK Go to your project, run:

go get google.golang.org/adk/v2

📖 Docs for AI coding agents

adk.dev/llms.txt is a machine-readable index of the ADK documentation, and adk.dev/llms-full.txt is the same documentation as a single file. Both are generated from adk-docs and include the Go API reference and samples, so you can point a coding agent at either one for context:

Plan and implement an agent that reviews customer issues and generates a report. Use the ADK Go framework, referring to https://adk.dev/llms-full.txt for sample code.
