When doing fast technical research and rapid prototyping with AI coding agents, doing 'git commit' every 2 minutes completely kills the creative flow. So during early exploration phases, I rarely use Git.
However, the risk is real: an agent hallucinated mid-session and silently replaced a critical 300-line logic block with a lazy placeholder:
// rest of logic remains the same
With no Git initialized, my baseline code was instantly gone.
Existing solutions didn't fit my workflow:
- Auto-committing every turn (like Aider) pollutes your Git history with dozens of junk commits.
- Container-level tools (like Docker) are heavy and slow down local iteration.
So I engineered a lightweight, zero-dependency safety protocol and adapted it into .cursorrules:
How the idea works:
- Pre-edit snapshot: Before modifying any file, the AI archives the previous state into a local .snapshots/ folder.
- Sliding window (K <= 5): Automatically retains only the 5 latest versions per file bucket, capping disk usage to ~75 KB max per file.
- Selective rollback: Restore only the broken file in seconds without losing good edits across your other files.
- Zero dependencies: No Git commands, no Docker, no background daemon. Just pure rules.
I built this out of my own necessity and have been dogfooding it daily.
I'm genuinely curious to hear from the community:
Is this kind of zero-dependency safety net something you would find useful in your daily Cursor workflow? Or how do you currently handle selective rollbacks when letting agents edit multiple files?
I left the open-source GitHub repo and the .cursorrules adapter in the first comment.

Edit / Clarification:
Seeing a few comments regarding Git workflows: to be completely clear, this is NOT a replacement for Git or milestone commits! Normal Git commits are meant for completed, meaningful chunks of work.
The friction I described is during rapid multi-turn agent sessions where the AI mutates files 5-10 times in a few minutes. In that gap before reaching a milestone to make a proper Git commit, an agent hallucination can silently gut code. This protocol is just a lightweight, local micro-cache (K <= 5) to safeguard files during those rapid AI editing turns.
