description	Build AI agents with Google Agent Development Kit (ADK) for Python. Use when creating multi-agent systems, tool-using agents, or orchestrating LLM workflows with Google Cloud.

Google ADK Python

Activate this skill when building AI agents with Google's Agent Development Kit.

When to Use

• Creating multi-agent orchestration systems
• Building tool-using AI agents
• Integrating with Google Cloud AI services
• Designing agent communication protocols
• Implementing RAG pipelines with ADK

Core Concepts

• Agent: Autonomous unit with instructions, tools, and model
• Tool: Function callable by the agent (Python functions, APIs)
• Session: Conversation state management
• Runner: Execution engine for agent invocations
• Orchestrator: Multi-agent coordination patterns

Setup

from google.adk import Agent, Tool, Runner

agent = Agent(
    name="data-analyst",
    model="gemini-2.0-flash",
    instructions="You analyze datasets and produce insights.",
    tools=[query_database, generate_chart],
)

runner = Runner(agent=agent)
response = runner.run("Analyze Q4 sales trends")

Patterns

• Sequential agent chains for multi-step analysis
• Parallel agents for independent data processing
• Supervisor pattern for quality control
• Tool composition for complex workflows

Rules

• Define clear agent boundaries and responsibilities
• Use typed tool parameters with Pydantic models
• Handle tool failures gracefully with retries
• Keep agent instructions concise and focused
• Test agents with deterministic inputs first
