taw-git — Branch, PR, Merge, Recover
For single-commit staging → use taw-commit instead.
For history lookup → use taw-trace.
When to invoke
Trigger phrases (VN + EN):
- "tao branch moi" / "new branch" / "tạo nhánh mới"
- "mo PR" / "create pull request" / "push len github" / "open pr"
- "merge branch vao main" / "merge feature"
- "huy commit" / "revert" / "undo last commit" / "quay lai"
Sub-commands
1. branch <name> — Create & switch
Branch naming with type prefix matching taw-commit conventions:
| Prefix | For |
|---|
feature/ | new user-visible feature |
fix/ | bug fix |
refactor/ | restructure, no behaviour change |
chore/ | deps, config, env |
hotfix/ | urgent production fix |
experiment/ | throwaway spike |
Workflow:
git fetch origin
git switch main
git pull --ff-only origin main
git switch -c <prefix>/<name>
If main is dirty (uncommitted work) → abort + VN: "taw: main đang có thay đổi chưa commit. Lưu trước rồi mới tạo branch."
2. pr [base] — Open pull request with smart body
Default base: main. Uses gh CLI against remote refs (unpushed commits visible on GitHub).
Preflight:
command -v gh >/dev/null || { echo "taw: gh CLI not installed. brew install gh"; exit 1; }
gh auth status >/dev/null 2>&1 || { echo "taw: gh not logged in. Run: gh auth login"; exit 1; }
git remote get-url origin >/dev/null 2>&1 || { echo "taw: no origin remote"; exit 1; }
Push current branch if not on remote:
HEAD_BRANCH="$(git rev-parse --abbrev-ref HEAD)"
[ "$HEAD_BRANCH" = "main" ] && { echo "taw: không mở PR từ main"; exit 1; }
git push -u origin "$HEAD_BRANCH"
Gather PR content (smart generation — not just commit dump):
BASE="${1:-main}"
git fetch origin "$BASE"
git log "origin/$BASE..origin/$HEAD_BRANCH" --pretty="- %s" > /tmp/taw-pr-commits.txt
git diff "origin/$BASE...origin/$HEAD_BRANCH" --stat > /tmp/taw-pr-stat.txt
Check for existing PR template:
cat .github/PULL_REQUEST_TEMPLATE.md 2>/dev/null || \
cat .github/pull_request_template.md 2>/dev/null
If project template exists → fill its sections. Else use taw's default template below.
Extract issue references:
git log origin/$BASE..origin/$HEAD_BRANCH --pretty=%B | \
command grep -oE '#[0-9]+|[Cc]loses #[0-9]+|[Ff]ixes #[0-9]+' | sort -u
echo "$HEAD_BRANCH" | command grep -oE '[0-9]+' | head -1
PR title — reuse the most significant commit subject (feat > fix > refactor > chore). Strip trailing [P<n>] tags. Max 72 chars.
PR body (default template when no project template):
## Summary
<1-3 bullets — WHAT and WHY, not commit dump>
- {outcome 1}
- {outcome 2}
## Changes
<Grouped by area, not files>
- **{area}** — {what changed there in plain terms}
## Test Plan
- [ ] {step 1 — usually run dev server, navigate to /route}
- [ ] {step 2 — golden-path action}
- [ ] {step 3 — edge case or failure mode}
- [ ] Run `npm test` — all pass
- [ ] Run `npm run build` — succeeds

🤖 PR body generated by taw-git
Open the PR:
gh pr create \
--base "$BASE" \
--head "$HEAD_BRANCH" \
--title "$TITLE" \
--body-file /tmp/taw-pr-body.md \
--web
For immediate submit: drop --web.
Without gh fallback: emit URL user pastes:
taw: tạo PR tại đây, paste body từ /tmp/taw-pr-body.md:
https://github.com/<owner>/<repo>/compare/<base>...<head>?expand=1
Post-create:
taw: PR opened — https://github.com/<owner>/<repo>/pull/<N>
Assign reviewer: gh pr edit <N> --add-reviewer <user>
Add labels: gh pr edit <N> --add-label <label>
3. merge [from] — Fast-forward merge into main
Only fast-forward. Non-ff requires manual review.
FROM="${1:-$(git rev-parse --abbrev-ref HEAD)}"
git switch main
git pull --ff-only origin main
git merge --ff-only "$FROM" || {
echo "taw: merge không phải fast-forward. Rebase '$FROM' lên main trước, hoặc merge thủ công."
exit 1
}
git push origin main
Offer to delete merged branch:
taw: merged $FROM → main. Xoá branch '$FROM'? (y/N)
On y:
git branch -d "$FROM"
git push origin --delete "$FROM"
4. undo — Recover from last commit
Interactive. Ask scenario:
| Scenario | Command | Effect |
|---|
| Đổi ý, sửa message | git commit --amend | Rewrites last commit msg |
| Bỏ commit, giữ file edit | git reset --soft HEAD~1 | Changes → staging |
| Bỏ commit + unstage | git reset HEAD~1 | Changes → working tree |
| Xoá hẳn (NGUY HIỂM) | git reset --hard HEAD~1 | All work gone — confirm twice |
Refuse --hard if commit touched >10 files or >200 lines UNLESS user types exact SHA.
Refuse any amend/reset if commit is pushed to protected branch (main | master | production). Instead suggest git revert <sha> (safe inverse commit).
Safety rules
- NEVER
git push --force to main | master | production. Force-push only to user-owned feature branches, with explicit confirmation.
- NEVER
git clean -fd (can delete untracked work).
- NEVER
gh pr merge --admin (bypasses branch protection).
- Before destructive op:
taw: sẽ chạy <cmd>. SHA hiện tại: <sha>. Xác nhận? (y/N)
- If
git status shows unmerged paths → refuse, tell user to resolve first.
- Diff sensitive-info scan (reuse
taw-commit patterns) before opening PR — block if token/secret appears in branch diff.
References (public specs — not copied, cited)
Output style
- Short prose in user's input language (VN default)
- Every user-visible line prefixed "taw:"
- Raw git/gh commands verbatim (English) — power users learn
- No emoji
