Google Agents CLI ADK Code
You get a quick reference for Google's Agent Development Kit with code examples in Python and Go. Claude uses it to write agents, tools, callbacks and workflows that follow ADK patterns.
What is Google Agents CLI ADK Code?
Google Agents CLI ADK Code is a skill for Claude Code that brings a reference for Google's Agent Development Kit (ADK). It contains cheatsheets with code examples for agent types, tool definitions, callbacks, plugins, state management, multi-agent systems and the graph-based Workflow API, split into Python and Go. The skill comes from Google, is licensed under Apache-2.0 and is at version 1.12.0.
Before Claude writes agent code, the skill checks with 'agents-cli info' whether a project has already been set up. You bring existing code in with 'agents-cli scaffold enhance .'. When you ask how to build a specific capability, the skill leads through a topic index to reference recipes in a Google repository, for example for RAG, sandboxed execution, memory across sessions or approvals before risky actions. For Go, the official example programs serve as templates.
The skill suits developers who build agents with ADK and want Claude to stick to the documented API patterns. It requires the agents-cli command line tool, which according to the skill you install with 'uv tool install google-agents-cli'. Project setup, evaluation and deployment have their own skills in the same repository, while this skill covers writing code.
Who it is for
Developers who build agents in Python or Go with Google's Agent Development Kit and use agents-cli for their projects.
Use cases
- You want to add a new tool or a callback to an existing ADK agent in Python and need the right pattern.
- You are planning an agent that asks a human for approval before risky steps and are looking for the matching reference recipe.
- Your team is building a voice assistant with ADK and needs to switch a scaffolded Python project to live operation.
What Google Agents CLI ADK Code does
Topic index of reference recipes
The file recipes.md maps capabilities such as RAG, sandboxed execution, memory across sessions or approvals before risky actions to a recipe that Claude studies before writing code.
Python reference for the ADK API
Cheatsheets on Agent, tools, callbacks, plugins, state, artifacts, SequentialAgent, ParallelAgent, LoopAgent, custom BaseAgent classes and the A2A protocol.
Go reference
A separate reference for ADK in Go covering llmagent, tools, callbacks, the runner, serving over HTTP, A2A and triggers, plus pointers to the official Go examples.
Graph-based Workflow API
Nodes, edges, fan-out and fan-in, human input and parallel processing for flows that a simple chain of agents cannot express, in Python and Go.
Live and voice agents
Guidance on Runner.run_live and LiveRequestQueue for real-time agents with voice or video, plus the changes needed in a scaffolded Python project.
Project check before coding
With 'agents-cli info' Claude first checks whether a project exists. Until a project has been set up, the skill tells Claude not to write agent code.

npx skills add google/agents-cli --skill google-agents-cli-adk-code
The command installs the original version from the author's repository (Vercel skills CLI, needs Node.js), add -g for all projects. We do not host a copy: updates come straight from the author. Need help with setup? How to install skills →

Good to know
- The skill requires the agents-cli command line tool and has Claude write code only once an ADK project has been set up.
- For recipes and documentation, Claude loads content from the web, including cloning a GitHub repository. This needs network access.
- The Workflow API requires google-adk version 2.0 or later in Python and the ADK library version 2.0 or later in Go.
- According to the skill, live agents cannot be served over A2A and cannot be published to Gemini.
- The check is an automated pattern search, not a security guarantee, and reads the skill folder only. The command always installs the author's current version; later versions have not been reviewed by us.
