google-agents-cli-adk-code
This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management", or needs ADK (Agent Development Kit) Python API patterns and code examples. Part of the Google ADK skills suite. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, and state management. Do NOT use for creating new projects (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).

What does this agent skill do?
ADK Code Reference
Before using this skill, activate
/google-agents-cli-workflowfirst — it contains the required development phases and scaffolding steps.
Prerequisites
- Run
agents-cli info— if it shows project config, skip to the reference below - If no project exists: run
agents-cli scaffold create <name> - If user has existing code: run
agents-cli scaffold enhance .
Do NOT write agent code until a project is scaffolded.
Python only for now. This reference currently covers the Python ADK SDK. Support for other languages is coming soon.
Quick Reference — Most Common Patterns
from google.adk.agents import Agent
def get_weather(city: str) -> dict:
"""Get current weather for a city."""
return {"city": city, "temp": "22°C", "condition": "sunny"}
root_agent = Agent(
name="my_agent",
model="gemini-flash-latest",
instruction="You are a helpful assistant that ...",
tools=[get_weather],
)

The first two are cheatsheets for common patterns; for broad or deep knowledge, go to the source (docs index or installed package).
| Reference | When to read |
|---|---|
references/adk-python.md | Core ADK API: Agent, tools, callbacks, plugins, state, artifacts, multi-agent systems, SequentialAgent / ParallelAgent / LoopAgent, custom BaseAgent, A2A protocol, A2UI. Default for most agents. |
references/adk-workflows.md | Graph-based Workflow API (ADK 2.0): nodes, edges, fan-out/fan-in, HITL, parallel processing. Use when you need explicit graph topology. |
curl https://adk.dev/llms.txt | Docs index (every page title + URL). Fetch it, then WebFetch the specific page for anything beyond the cheatsheets. |
| Installed ADK package | Exact signatures and symbols — inspect the source (see "Inspecting ADK Source Code" in references/adk-python.md). |
