Rebase the current branch.

Arguments: $ARGUMENTS

Behavior

• No arguments: fetch origin, update local default branch, rebase onto it
• "origin": fetch origin, update local default branch, rebase onto it
• "origin/branch": fetch origin, update local branch, rebase onto it
• "branch": fetch origin, update local branch, rebase onto it

Steps

1. Determine the default branch by running: git remote show origin | awk '/HEAD branch/ {print $NF}'
2. Parse arguments:
   • No args → target branch is
   • Contains "/" (e.g., "origin/develop") → extract branch name after "/"
   • Just "origin" → target branch is
   • Anything else → target branch is the argument
3. Run: git fetch origin
4. Run: git rebase <branch> (using local branch, not origin/branch)
5. If conflicts occur, handle them carefully (see below)
6. Continue until rebase is complete

Handling conflicts

• BEFORE resolving any conflict, understand what changes were made to each conflicting file in the target branch
• For each conflicting file, run git log -p -n 3 <target> -- <file> to see recent changes to that file in the target branch
• The goal is to preserve BOTH the changes from the target branch AND our branch's changes
• After resolving each conflict, stage the file and continue with git rebase --continue
• If a conflict is too complex or unclear, ask for guidance before proceeding

Output

IMPORTANT: Be silent during execution. Do not narrate your actions or explain what you're doing.

When complete, output ONLY a compact summary in this exact format:

Rebased N commits onto <target>
[If conflicts:]
  - <file>: <one line describing resolution>
  - <file>: <one line describing resolution>

Nothing else. No explanations, no status updates, no tool output.
