Rearrange Commits

Reorganize all commits on the current branch into clean, logical, atomic commits.

Instructions

Step 1: Analyze Current State

Resolve the base branch at runtime rather than assuming main. Every shell block runs in a fresh shell, so each block below that uses BASE re-assigns it first. Fall back to the repo default only when gh pr view confirms there is no PR for this branch yet; abort on any other failure (auth, network, API) instead of guessing:

BASE=$(gh pr view --json baseRefName --jq .baseRefName 2>&1) || { case "$BASE" in *"no pull requests found"*) BASE=$(gh repo view --json defaultBranchRef --jq .defaultBranchRef.name) ;; *) echo "Unable to resolve the base branch: $BASE" >&2; exit 1 ;; esac; }
[ -n "$BASE" ] || { echo "Unable to resolve the base branch" >&2; exit 1; }
echo "Base branch: $BASE"
git fetch origin || { echo "Fetch failed: STOP, origin/$BASE may be stale" >&2; exit 1; }
git branch --show-current
git log "origin/$BASE"..HEAD --oneline
git diff "origin/$BASE"...HEAD --stat
git status

Step 2: Preserve All Changes

Never use git stash here: the stash stack is shared by every worktree and session of this repository, so a pop can restore someone else's changes. Commit uncommitted work instead, and keep a backup branch until the rearranged history is verified.

1. Commit any uncommitted changes as a WIP commit (review git status first, so nothing that must not be committed, such as secrets or scratch files, is included):

   if [ -n "$(git status --porcelain)" ]; then
     git add -A && git commit -m "chore: WIP snapshot before rearrange" \
       || { echo "WIP commit failed (hook, signing or staging error): STOP, nothing was reset" >&2; exit 1; }
   fi
   

2. Create a uniquely named backup branch and note the printed name, since later blocks re-assign BACKUP to it. The tree must be fully committed first, or the Step 4 recovery would drop the uncommitted work:

   [ -z "$(git status --porcelain)" ] || { echo "Uncommitted changes remain: STOP before creating the backup" >&2; exit 1; }
   BACKUP="backup/rearrange-$(date +%s)-$$-$RANDOM"
   git branch "$BACKUP" || { echo "Failed to create backup branch $BACKUP: STOP before resetting" >&2; exit 1; }
   echo "Backup branch: $BACKUP"
   

3. Soft reset to the point where this branch forked from the base, and note the printed SHA. Use the fork point (git merge-base), not origin/$BASE itself: if the base branch moved since this branch was last rebased, committing the branch's tree on top of the newer base would silently revert everything the base gained in between.

   BASE=$(gh pr view --json baseRefName --jq .baseRefName 2>&1) || { case "$BASE" in *"no pull requests found"*) BASE=$(gh repo view --json defaultBranchRef --jq .defaultBranchRef.name) ;; *) echo "Unable to resolve the base branch: $BASE" >&2; exit 1 ;; esac; }
   [ -n "$BASE" ] || { echo "Unable to resolve the base branch" >&2; exit 1; }
   FORK_POINT=$(git merge-base HEAD "origin/$BASE")
   echo "Fork point: $FORK_POINT"
   git reset --soft "$FORK_POINT"
   git reset HEAD .
   

   All changes, including the WIP snapshot, are now unstaged in the working tree.
