Background

Claude SDK and many tools are built around Claude CLI. However, the underlying protocol was largely undocumented, preventing SDK implementation in other languages. This project provides:

1. Protocol Documentation - Generated from the Python SDK, capturing the exact wire protocol
2. Language SDKs - Native implementations for multiple languages
