I know you can just ask an agent to find them, and a lot of people do exactly that. but I wanted a deterministic solution that wouldn't depend on an agent getting things right or waste extra tokens.
so.. I built Lopper!
it's a tool that searches for git repositories and worktrees across different directories on your machine and shows them all in one place in a TUI, where you can inspect them and remove the ones you no longer need. it also has a CLI for scripts and agents, so they can manage worktrees more reliably.
would you use something like this? what am I missing compared to just asking an agent to handle it?
