Claude Agent SDK
Anthropic's official SDK for building autonomous Claude agents.
The Claude Agent SDK gives you a structured, tested toolkit for building Claude-powered agents — tool use, memory, harness, and the same primitives Claude Code is built on.
Pros
- ✅ Official, well-tested abstractions
- ✅ Same primitives as Claude Code
- ✅ Strong tool-use ergonomics
Cons
- ⚠️ Claude-only
- ⚠️ Newer than LangGraph/CrewAI
