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...

ADK Code Reference

Before using this skill, activate /google-agents-cli-workflow first — 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],
)

References

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`. 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`).
