About

ADK for TypeScript defines agents, tools and orchestration in code and runs them in Node.js or in the browser. Tool parameters are typed with Zod schemas, and agents can be combined into sequential, parallel, loop and routed workflows, or call remote agents over A2A. The package ships a CLI and a dev UI for running and testing agents locally. The adk.dev page lists the TypeScript 2.0 release as GA with graph workflows.

Use cases: agent-orchestration, backend-development
