git

Advanced Git CLI mastery, recovery, and troubleshooting (git 2.54+). Use whenever a git task goes beyond the basics — recovering lost commits/branches/stashes (reflog, fsck), undoing a bad reset/merge/rebase/amend, rewriting history (interactive rebase, --autosquash, --update-refs, filter-repo), resolving merge conflicts or using rerere, working with worktrees, bisect, cherry-pick, revert, or stash, understanding refspecs/remotes/push behavior and --force-with-lease, configuring .gitattributes/.gitignore/hooks, exploring git internals (object model, plumbing like cat-file/rev-parse), or diagnosing confusing errors (detached HEAD, dubious ownership, non-fast-forward, CRLF). Trigger even when the user doesn't name the exact command but is clearly stuck or doing something non-trivial in git. For commit-message wording use conventional-commits; for stacked/dependent branches use git-chain; for auto-folding fixups use git-absorb; for Jujutsu use jj.
