Adding an Undo Button to AI Coding Agents
Lumpy-Guarantee-475 · reddit · 2026-07-14
The author developed a tool called Rewind that automatically creates checkpoints for AI coding agents.
It solves the problem where an agent makes continuous changes across multiple files, making it hard to pinpoint exactly which step caused an error. Instead of a blanket git checkout . to roll back everything, Rewind lets users inspect changes at specific points or jump back to any checkpoint in the session.
The tool also supports:
- Single-file recovery
- Automatic rollback on test failures
- Automatic safe backups before recovery
- Detecting agent modifications to instruction files like CLAUDE.md
It works by monitoring the file system, making it tool-agnostic and compatible with Claude Code, Cursor, Copilot, Aider, OpenHands, Gemini CLI, etc. The project is open-source under the MIT license.
