An open-source, code-first Go toolkit for building, evaluating, and deploying sophisticated AI agents with flexibility and control.
Google's ADK for Go is the official Go-language implementation of the Agent Development Kit, a modular framework for building, evaluating, and deploying AI agents using idiomatic Go patterns. Developers define agent logic, tools, and orchestration directly in Go code, then compose multiple specialized agents into multi-agent systems that can tackle complex workflows. The toolkit integrates with MCP (Model Context Protocol), supports the Agent-to-Agent (A2A) communication standard, and connects to Gemini models via Vertex AI, though it remains model-agnostic and can work with other LLM backends. Agents can be containerized and deployed to environments like Google Cloud Run. Installed via a single `go get google.golang.org/adk` command, the framework targets Go developers building cloud-native agent applications who want to leverage Go's concurrency model for agent orchestration. Claude can participate in these systems as a subagent or peer through MCP tooling, making this relevant to teams running heterogeneous multi-model architectures alongside Google's own Gemini offerings.

Author or rework a runnable example under `examples/` in the ADK Go repository — the directory, `main.go`, the README with its Mermaid diagram and real transcript, and the index row. Use when adding a sample for a feature (workflow graph, tool, registry client, model backend, server), when asked to "add an example" for something, or when bringing an existing example up to the repo's standard.

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:
```bash
go get google.golang.org/adk/v2
```
## 📖 Docs for AI coding agents
[adk.dev/llms.txt](https://adk.dev/llms.txt) is a machine-readable index of the ADK documentation, and [adk.dev/llms-full.txt](https://adk.dev/llms-full.txt) is the same documentation as a single file. Both are generated from [adk-docs](https://github.com/google/adk-docs/) and include the Go API reference and samples, so you can point a coding agent at either one for context:
```text
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.
