Rebase assistant

Goal

Rebase the current branch onto a target branch safely, with built-in conflict resolution guidance.

Inputs to confirm (ask if missing)

• Target branch (explicit branch name or "default branch").
• Preferred conflict bias when ambiguous: keep ours, keep theirs, or manual merge.
• Protected paths or file types to avoid touching.

Workflow

1. Identify the target branch
   • If user says "default branch": discover via git remote show origin (read "HEAD branch").
   • If ambiguous or no remote: ask the user which branch to use.
2. Preflight checks
   • git status -sb (must be clean before rebase).
   • git fetch --prune to sync remotes.
   • Optional safety branch (ask before creating): git branch backup/<current-branch>.
3. Start the rebase
   • git rebase <target-branch>
4. If conflicts occur, resolve (repeat per file)
   • Inspect conflict list:
     • git status -sb
     • git diff --name-only --diff-filter=U
   • Classify and inspect:
     • Content conflicts: open file, resolve markers.
     • Delete/modify or rename conflicts: decide keep vs delete explicitly.
     • Binary conflicts: choose ours/theirs only.
   • Show base/ours/theirs when useful:
     • git show :1:<path>
     • git show :2:<path>
     • git show :3:<path>
   • File-level choice when safe:
     • git checkout --ours <path>
     • git checkout --theirs <path>
   • Stage resolved files: git add <path>
   • Continue: git rebase --continue
5. Finish and verify
   • Ensure no conflicts: git status -sb
   • Suggest a fast test/build if available.

Safety rules

• Never run git reset --hard, git clean -fd, or git rebase --abort unless the user explicitly requests it.
• Always show candidate commands before applying destructive changes.

Deliverables

• The exact rebase command used and target branch.
• Conflict list grouped by type with per-file resolution guidance.
• Completion command and a short verification suggestion.
