A new Hacker News Show post introduces Unlose, an open-source utility designed to automatically create Windows Volume Shadow Copy Service (VSS) snapshots before AI agents execute file operations that could result in data loss.
The Problem It Addresses
As AI coding assistants become more integrated into developer workflows, cases of agents deleting critical filesβwhether through misinterpreted instructions, corrupted prompts, or aggressive refactoring commandsβhave become increasingly common. Unlose attempts to solve this by proactively capturing system state snapshots when it detects an AI agent is about to modify files.
How It Works
The tool integrates with the Windows VSS infrastructure, which has been a built-in part of the operating system since Windows XP but remains underutilized by most users. When enabled, Unlose monitors file operations and creates restore points automatically, allowing developers to roll back changes if an AI agent makes destructive mistakes.
Availability And Limitations
Unlose is available on GitHub at github.com/unlose-app/unlose as an open-source project. At the time of posting, it had received limited visibility on Hacker News with only a handful of points and no comments, suggesting it's still early in its development lifecycle or hasn't yet gained significant community traction.
Key Takeaways
- Unlose targets a real pain point: AI agents accidentally deleting important files during coding tasks
- Uses Windows-native VSS infrastructure rather than requiring third-party backup solutions
- Still very early stage based on Hacker News engagement metrics
- Open-source approach allows power users to audit and extend the functionality as needed
The Bottom Line
This is exactly the kind of tooling the AI agent ecosystem needs more ofβdefensive safeguards built around the assumption that these systems will make mistakes. Whether Unlose specifically becomes the standard remains to be seen, but expect similar protective utilities to proliferate as AI coding assistants become mainstream.
