Claude Agent SDK

The Agent SDK provides Claude with autonomous tool execution. Unlike the Messages API where you implement the tool loop, agents execute tools automatically.

Quick Start

Python:

import asyncio
from claude_agent_sdk import query, ClaudeAgentOptions

async def main():
    async for message in query(
        prompt="Find and fix the bug in auth.py",
        options=ClaudeAgentOptions(allowed_tools=["Read", "Edit", "Bash"])
    ):
        print(message)
