Claude Code removed the multi-edit tool (twitter.com)

Anthropic has removed the “multi-edit” tool from Claude Code — the feature that let users apply a single instruction to edit multiple code locations or files at once. The takedown wasn’t accompanied by a detailed public explanation, but users immediately noted the loss of a fast path for global refactors, synchronous multi-hunk repairs, and batch transformations that previously reduced tedious copy‑paste and manual multi-file edits. The change matters because multi-edit capabilities are a practical multiplier for developer productivity and for toolchains that rely on LLMs to propose coordinated changes (variable renames, cross-file API migrations, or consistent security fixes). Without it, workflows that depended on atomic, consistent edits across files risk becoming more error-prone or slower; teams will lean more on language-server refactoring, static analysis, CI enforcement, or other LLMs/plugins that still support batch edits. Technically, the removal may reflect tradeoffs Anthropic faces around correctness, patch consistency, edit conflict resolution, or safety/abuse surface area when an AI rewrites many locations at once — all areas that can introduce subtle bugs. Developers should plan immediate workarounds (local refactor tools, patch-based LLM prompts, or alternative assistants) while watching for a clarified rationale or an updated, safer multi-edit implementation.
