Claude Code Undo feature

[BradKML]

This is probably going to be important so I will be noting this as an issue, Claude Code should have an undo/rewind/checkpoint feature, and a lot of them vary based on how automated they are

Thanks for providing so many excellent solutions. I’ve only tried ccundo before, but it didn’t quite meet my expectations; after reviewing them all, Rewind-MCP seems the most user-friendly—I plan to give it a try. Additionally, CCheckpoints’ UI approach also looks great.

Ideally, undos are Git-independent (don't need grounding in GitHub/Gitlab/etc), and don't set too many/few checkpoints. Summaries similar git commit messages are a good-to-have, but changelogs are ultimately reliant on other PM systems.

P.S. this might be related to session management #37

Would love to know how ZCU differs from the big players https://github.com/UfoMiao/zcu

Currently, it is still in the architecture construction phase, here is claude code polished response🤣：
ZCU vs Big Players - Key Differentiators:

⚡ Technical Architecture

• ZCU: LevelDB + Shadow Repository + AI session isolation
• Git: Heavy-weight, development history focused, complex manual operations
• IDE Undo: Single-file limitations, can't handle AI batch operations

🚀 Unique Advantages

• Smart Session Isolation: Multiple Claude instances work simultaneously without
  conflicts
• Dual UI Architecture: Terminal (Ink) + Web dashboard sharing same component
  library
• Natural Language Commands: Control via cc command with plain English /zcu undo recent
  changes then add checkpoint
• Lightweight & Fast: ~200KB storage engine vs Git's complexity overhead

💡 Use Case Focus

• ZCU: Real-time protection and instant rollback for AI programming sessions
• Git: Version history management and team collaboration
• Traditional Undo: Simple text editing reversals

Bottom line: ZCU is the "time machine" for AI-era programming tools -
professional, lightweight, and intelligent. ✨

Compare ZCU with the big players in "Undo MCP", cus that is probably the easiest comparison.
P.S. what is your opinion of jj being seen as an alternative of git or "gitalias"? https://github.com/jj-vcs/jj https://github.com/GitAlias/gitalias
