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.

ADK Code Reference
Before using this skill, activate /google-agents-cli-workflow first — it contains the required development phases and scaffolding steps.
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, 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).

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.
