claude-agent-sdk-for-python

Features and purpose

Expert guidance for building autonomous AI agents using Anthropic's Claude Agent SDK (Python). Covers: agent loop patterns (GTVR: gather context, take action, verify, repeat), ClaudeSDKClient and query() APIs, streaming vs single-mode execution, custom tool design with @tool decorator, MCP server integration, hooks for runtime control, permission models, authentication (API key vs subscription OAuth, token lifecycle, environment handling), context management, subagent orchestration, and production deployment patterns. Use when: building custom agents, implementing tool pipelines, designing multi-agent systems, integrating external services via MCP, configuring authentication for SDK clients, or deploying agents to production. Not for: basic chat completion or non-agentic workflows.
