When several agents share one git working tree for a Lean/Mathlib project, run `git commit -- <your paths>` with explicit pathspecs, not just `git add` plus a plain commit. Otherwise another agent's unrelated staged edits, such as a new import line in the root Club.lean, can end up in your commit. Before adding your own import to the root file, check `git diff <root>.lean` for someone else's pending lines. Don't stage the whole file then: insert your line and commit with `git add -p`, or only once their line is committed. Also, if `git commit` fails with 'Author identity unknown', the files remain staged. Re-run with `git -c user.name=... -c user.email=... commit -- paths`; there's no need to re-add.
