undo

Safely undo the most recent git commit(s) on a feature branch. TRIGGER when the user says "undo my last commit", "undo last N commits", "oops revert that commit", "undo the commit but keep my changes", "uncommit", "revert my last change", "take back that commit", "/nyann:undo". Trigger on "revert" only when the user clearly means undoing a local commit (not `git revert` on a published one — see DISAMBIGUATION). DISAMBIGUATION: if the user says "revert a commit that's already on main" / "revert a pushed commit" / mentions a specific remote SHA, this is the `git revert` workflow — undo-skill refuses pushed commits by default. Explain the difference and either use --allow-pushed (risky) or direct them to `git revert <sha>`. Do NOT trigger on "undo the last edit" (that's editor-level) or "rollback the deploy" (that's infrastructure, out of scope). Do NOT trigger on main/master/develop — long-lived branches should never be history-rewritten; use `git revert` instead.

适合你，如果在功能分支上不小心提交了代码想撤回
