--- name: no-git-stash-shared-checkout description: Another Claude session may be editing/staging in the same agenthub checkout at the same time — never git stash to compare against HEAD metadata: type: feedback --- On 2026-10-06 a parallel session committed v2.5.6 and staged new tmux/package changes in this checkout while I was working; my `git stash`/`stash pop` (to rerun a test on clean code) briefly hid whatever was in the tree. **Why:** stash/pop is checkout-wide; it can swallow or unstage another session's in-flight work. **How to apply:** to test against clean code use `git worktree add /tmp/ HEAD` instead. Before reporting, check `git status` for staged changes that are not yours and leave them alone. See [[agenthub-multi-user-goal]].
