Nothing surprising and OP seem understandable of what have happened. But I should maybe take the opportunity here and remind you guys to:

- Use version control

- Backup your things somewhere (not same drive or use Cloud / NAS whatever), Windows have a cool feature called File history! But no one trusts Windows anyways so stick to external backup

- Restrict the agent a lot, make it least-privileged user

- Restrict it in a virtualized filesystem so it cannot work outside of its scope

- Devcontainers?

- Do not use auto allow actions, always supervise the actions it wants to perform outside reading/writing code

- Avoid fully automated agents at all outside of sandboxed environments haha
