/finalize — Prepare Branch for Fast-Forward Merge

Rewrites commits in main..HEAD so branch fast-forwards onto main as clean Conventional Commits sequence. Rebasing phase of two-phase branch workflow — see workflow-git.md for full model.

Sibling /commit skill handles working phase (save progress during dev). /finalize takes messy result, produces what lands in main-branch changelog.

When To Use

Situation	Use
Branch has multiple Checkpoint commits	/finalize
Branch has working-phase bundles ("chore(claude): bundle skill + rules + agents")	/finalize
Rebasing branch onto current main before fast-forward	/finalize
Branch is one changelog entry with noise between	/finalize --squash-all
Already one-concern-per-commit and rebased	don't — fast-forward

Flags

• --squash-all — skip per-commit analysis, collapse main..HEAD into single commit. Skill drafts one message for whole diff, asks approval.
• --dry-run — produce classification + rebase plan, show, no execute. Useful for review.
• --force — skip the active-phase check (still honors other refuse conditions). Use when no plan tracks the branch or Status block is intentionally stale.

Workflow

1. Snapshot state (parallel batch)

• git rev-parse --abbrev-ref HEAD — current branch
• git status --porcelain=v1 — working tree clean?
• git fetch origin main --quiet 2>/dev/null then git rev-parse main and git rev-parse origin/main 2>/dev/null — detect if local main lags origin/main
• git log --oneline main..HEAD — commits to finalize
• git log -1 --pretty=%s main — tip of main (plan reference)
• git rev-list --count main..HEAD — commit count
• git diff --stat main..HEAD — diff shape
• git merge-base --is-ancestor main HEAD; echo $? — local main ancestor of HEAD? (0 = yes, branch based on current local main; 1 = no, needs rebase onto main as part of finalize)

Refuse to proceed if:

• Current branch is main — tell user switch to feature/worktree branch first.
• main..HEAD empty — nothing to finalize.
• Working tree dirty — tell user commit or stash with /commit first. No auto-stash; user must consciously save state.
• Plan still in flight — read .claude/state/current_plan.md; if pointer present, parse the referenced plan's ## Status block. Refuse if Step is not finalized/awaiting /finalize or Active phase is not the last plan phase. --force overrides. Schema → plan-status.md.

Rebase target — always current local main. /finalize produces branch fast-forwarding onto local main HEAD. Two cases:

1. Branch already based on current main (merge-base --is-ancestor main HEAD returns 0). Rebase only rewrites commits in main..HEAD for hygiene — no parent change, no upstream-drift conflict risk.
2. Branch behind main (returns 1). Rebase does double duty: rewrites commits in main..HEAD for hygiene and moves branch onto current main HEAD. Conflicts here real, human resolves (see Step 4).

Both cases use git rebase -i main, replays merge-base..HEAD onto current main.

origin/main handling. If local main behind origin/main, surface before drafting plan, ask user how to proceed:

Option	Effect
Fast-forward local main first, then finalize (default)	git fetch origin main && git checkout main && git merge --ff-only origin/main && git checkout <branch> then continue. Branch lands on top of latest published main.
Finalize against current local main	Skip fetch. Branch fast-forwards onto local main but may lag origin once published.
Abort	Stop without changes.

Never touch origin/main directly (no force-push, no remote updates beyond fetch).

2. Classify each commit in main..HEAD

For every commit in main..HEAD, assign one category:

Category	Signal	Action
Keep	Clean Conventional Commits subject, single concern, useful changelog entry	Leave alone
Reword	Single concern but subject non-conventional, typo'd, or mis-typed (e.g. fix: for real feat:)	Rewrite subject only, keep diff
Squash	Two+ adjacent commits cover same concern (fix + follow-up fixup, feat + missed test, rolling checkpoint amendments)	Collapse into one with drafted message
Split	One commit mixes unrelated concerns	Offer git reset HEAD^ workflow; defer to human if non-trivial
Drop	Empty commit, reverted earlier in branch, pure noise	Remove
Checkpoint	Subject exactly Checkpoint	Reword (single concern inside) or squash into neighbour

Classification heuristics:

• Subject line first. Non-conventional → Reword candidate.
• git show --stat <sha> for diff shape. Small diff, one module → likely Keep/Reword. Large diff, many modules → inspect body for multi-concern signals (- bullet lists, and, also, plus, bundle language).
• chore(claude): commits touching only .claude/ or CLAUDE.md belong in working-phase, but on finalized branch should still be individually legitimate chore(claude): entries, not bundles.
• git log --format=%B <sha> -1 for full message when subject ambiguous.

3. Draft the rebase plan

Present as numbered list user can scan. Example:

Rebase plan for evelynn (5 commits in main..HEAD):

  1. KEEP    a2a7072 feat(mirror): per-platform asset_type override
  2. SQUASH  b1c2d3e Checkpoint              → fold into (3)
  3. REWORD  e4f5g6h chore(claude): wip             → feat(cli): add --remote flag to catalog
  4. DROP    9a8b7c6 Revert previous wip fix  (undone later in the branch)
  5. KEEP    1234567 docs(guide): document --remote flag

Target base: main (039c066)
Final commit count: 3

Use AskUserQuestion with three options:

Option	Effect
Execute plan (default)	Run scripted rebase
Edit plan	Let user adjust before exec (describe change in prose, redraw)
Abort	Stop without changes

If user picked --dry-run, print plan and stop regardless of choice.

4. Execute the rebase (non-interactive)

Use scripted non-interactive git rebase -i pattern — never launch $EDITOR. Base always current local main, so same command both rewrites internal history (per plan) and replays branch onto latest local main HEAD.

# Capture starting state for emergency rollback
START_SHA=$(git rev-parse HEAD)

# Build a rebase-todo file from the plan, then run rebase with
# GIT_SEQUENCE_EDITOR pointing at `cat` on that file, and
# GIT_EDITOR pointing at a script that replaces any commit message
# during reword/squash with the pre-drafted one.
GIT_SEQUENCE_EDITOR="cp $TODO_FILE" \
GIT_EDITOR="$MSG_SCRIPT" \
git rebase -i main

Implementation notes:

• Generate rebase-todo file in temp dir. Each line is pick|reword|squash|fixup|drop <sha> <subject>.
• For reword/squash, pre-write target message to files named by SHA; GIT_EDITOR script reads matching file, overwrites message.
• On rebase conflict: stop, print conflicted file list, tell user what to do (git status, edit, git rebase --continue), exit. Do not auto-resolve.
• On success: show rewritten git log --oneline main..HEAD and final commit count.
• Backout: git rebase --abort (if still rebasing) or git reset --hard $START_SHA (if rebase done but user unhappy). Offer both explicitly.

5. --squash-all mode

When --squash-all passed, skip steps 2–4, instead:

1. Draft single Conventional Commits message covering full main..HEAD diff. Read git log main..HEAD for scope/concern inspiration but result is one commit — subject describes real user-visible change, not enumerate fixups.
2. Show drafted message. Ask approval.
3. Execute:

   git reset --soft main
   git commit -m "$(cat <<'EOF'
   <drafted message>
   EOF
   )"
   

4. Report new HEAD sha + subject.

Squash-all right when branch really one changelog entry — e.g. feature across 8 checkpoints + 3 fixups. Wrong when branch has independent concerns (refactor + unrelated bug fix) — decline, use per-commit plan instead.

6. Quality gate after rebase

After rebase, task verify must still pass on new HEAD. Run it. On fail:

1. Show failure.
2. User fixes (rebases can expose test interactions invisible in messy history).
3. On fix, rerun /commit (working phase for fix) then /finalize again if more shaping needed.

No push. Never push.

7. Mark plan finalized + clear current_plan.md

After successful rebase, if a Status block exists in the plan referenced by .claude/state/current_plan.md: set Step: to finalized, bump Last update: (with new HEAD sha), delete .claude/state/current_plan.md. Skip silently when no plan / no Status block / --force was used.

8. Report

Starting → final commit count, whether task verify passed, whether Status was marked finalized and current_plan.md cleared, next step for user (git checkout main && git merge --ff-only <branch> if asked; else stop).

Safety Rules

• Always capture START_SHA before first destructive op. Offer git reset --hard $START_SHA as recovery command if user unhappy.
• Never force-push. Skill only rewrites local history. Human decides push.
• Never touch commits already on origin/<branch> without explicit confirmation. Rewriting published history fine on feature branch human controls, but skill must flag (git rev-list origin/<branch>..HEAD for local-only vs published).
• Never auto-resolve conflicts. On conflict, stop, hand back to user.
• Never launch $EDITOR. Always scripted GIT_SEQUENCE_EDITOR + GIT_EDITOR pattern with pre-written files.
