Show HN: Graft – Claude Code hooks that cut grep tokens by 42%

Graft significantly enhances Claude Code, Cursor, Codex, and Gemini by improving correctness and efficiency. It achieved a 12-point increase in correctness, resolving 33 out of 50 instances compared to Cold Claude Code's 27. This improvement came with 23% fewer tokens, 25% fewer tool calls, and 32% less wall-clock time, leading to 19% cost savings. Graft also offers compiler-grade edges via graft build --lsp for languages like Rust, C/C++, Go, Python, and TS/JS, using language servers such as rust-analyzer and clangd.
