Claude Agent SDK

Build AI agents that autonomously read files, run commands, search the web, edit code, and more. The Agent SDK gives you the same tools and agent loop that power Claude Code, programmable in Python and TypeScript.

Renamed: The Claude Code SDK is now the Claude Agent SDK. Package names changed to claude-agent-sdk (Python) and @anthropic-ai/claude-agent-sdk (TypeScript).
