Claude Code Agent SDK

A high-performance CLI and SDK for building autonomous coding agents that execute complex refactors and terminal commands directly.

Claude Code transforms the model into a hands-on engineer capable of managing the full development lifecycle. It integrates directly with local environments to edit files, run test suites (like Vitest or Pytest), and debug build errors in real time. By utilizing the Anthropic SDK, developers can automate repetitive migrations and codebase-wide updates with 100% precision. It is the definitive tool for teams moving from simple chat interfaces to fully autonomous software engineering workflows.
