A blog post investigates the "over-editing" problem where coding models like Claude Code, GitHub Copilot, and Cursor unnecessarily rewrite code beyond what's needed to fix a bug. The author examines whether LLMs systematically exhibit this behavior and explores training approaches for more minimal, faithful edits. Excessive rewrites make code review harder and obscure actual changes.
