An open-source, code-first TypeScript toolkit for building, evaluating, and deploying sophisticated AI agents. It empowers developers seeking fine-grained control and flexibility, particularly for deep integration with Google Cloud services, by enabling robust debugging, versioning, and deployment across environments.

How It Works

ADK-JS leverages a code-first paradigm in TypeScript, allowing developers to define agent logic, orchestration, and tool usage directly within their codebase. This approach enhances testability, version control, and deployment flexibility. The toolkit supports modular multi-agent systems, facilitating the composition of specialized agents into scalable, hierarchical structures. It features a rich tool ecosystem, enabling seamless integration of pre-built tools, custom functions, and OpenAPI specifications, with a focus on tight integration within the Google ecosystem.

Quick Start & Requirements

• Installation: npm install @google/adk or yarn add @google/adk.
• Prerequisites: TypeScript development environment.
• Documentation: Docs, Samples.

Highlighted Details

• Rich Tool Ecosystem: Integrates pre-built tools, custom functions, OpenAPI specs, and existing tools, emphasizing tight integration with Google services.
• Code-First Development: Agent logic, tools, and orchestration defined in TypeScript for enhanced flexibility, testability, and versioning.
• Modular Multi-Agent Systems: Enables the design of scalable applications through the composition of multiple specialized agents into flexible hierarchies.
• Development UI: Includes a built-in UI for testing, evaluating, and debugging agents, mirroring the experience of the Python ADK.

Maintenance & Community

The project actively welcomes community contributions, including bug reports, feature requests, and code submissions, with dedicated contribution guidelines available. Specific community channels like Discord or Slack are not detailed in the provided text.

Licensing & Compatibility
