Basic Agent
from google.adk.agents import Agent
from google.adk.tools import FunctionTool
def get_weather(location: str) -> str:
return f"The weather in {location} is 22C and sunny."
agent = Agent(
name="weather_agent",
model="gemini-2.0-flash",
instruction="You are a helpful weather assistant.",
tools=[FunctionTool(get_weather)],
)
response = agent.run("What's the weather in Paris?")
print(response.content)
Multi-Agent Handoff
research = Agent(name="researcher", model="gemini-2.0-flash", ...)
writer = Agent(name="writer", model="gemini-2.0-flash", ...)
reviewer = Agent(name="reviewer", model="gemini-2.0-flash", ...)
from google.adk.runners import Runner
runner = Runner(agents=[research, writer, reviewer])
result = runner.run("Research and write about quantum computing.")
