I push my branches daily, so I wouldn't lose that much work. If it breaks then I ask it to fix it.

But I do quickly check the output what it does, and especially the commands it runs. Sometimes it throws all code in a single file, so I ask for 'good architecture with abstractions'.

I see this regularly: "I use GitHub to backup my local repos."

If `gh repo ...` commands get run you can lose everything instantly. You can force push and be left with a single blank commit on both sides. The agent has full control of everything, not just your local data.

Just set up Rclone/restic and get your stuff into a system with some immutability.
