Score: 6.3/10 (Innovation: 5, Technical: 7, Documentation: 7, Utility: 6)

Patchwork is a lightweight CLI tool that uses tree-sitter ASTs to perform structural code search and replacement, similar to sed but with syntax-aware matching. It offers a small binary, zero configuration, and a unique placeholder syntax, making it interesting for developers who need quick, accurate refactors without heavy dependencies or LLMs.

Target audience: backend devs
