Tổng quan

Google's Agent Development Kit (ADK) is a Python-based framework designed for creating agentic applications. Version 2.0 introduces a graph-based Workflow Runtime for deterministic execution flows and a Task API for structured agent-to-agent delegation. It allows developers to define individual AI agents and orchestrate them using workflows, supporting complex routing, loops, and human-in-the-loop interactions.

Tính năng chính

  • Code-first Python toolkit
  • Graph-based Workflow Runtime
  • Task API for structured agent-to-agent delegation
  • Support for routing, fan-out/fan-in, loops, and nested workflows
  • Human-in-the-loop capabilities
  • Interactive CLI and Web UI for local running
  • Bi-weekly release cadence

Yêu cầu, cài đặt và bắt đầu nhanh

Install the core package using pip: `pip install google-adk`. For transitive dependency protection, it is recommended to download and use the constraints file matching your Python version (e.g., `curl -o constraints-3.10.txt https://raw.githubusercontent.com/google/adk-python/main/constraints-3.10.txt` and `pip install google-adk -c constraints-3.10.txt`). Optional integrations can be installed via `pip install "google-adk[extensions]"`.

Cách sử dụng

Define an agent by instantiating the `Agent` class with a name, model, and instruction. Define a `Workflow` by specifying edges that connect agents in a graph. Run applications locally using the command line interface (`adk run path/to/my_agent`) or launch a web interface (`adk web path/to/agents_dir`).
