claude-code-sdk: Reverse-engineered Claude Code
SMRTR summary
Developers reverse-engineered Claude Code's CLI binary and created lightweight, single-file SDKs in four languages (Node.js, Python, Go, Rust) with zero dependencies. These tools authenticate via OAuth using existing Pro/Max subscriptions, implement full agent loops with streaming and tool calling, and expose NDJSON protocols for programmatic integration without the original 190MB binary overhead.
