Git Workflow

Switch over checkout

Use git switch for branch operations. Never git checkout. checkout -- silently destroys uncommitted work, and checkout <branch> is ambiguous when a file shares the name. switch only switches branches. Use git restore for file-level operations.

Trunk-based, small PRs

Target ≤ 200 lines of changed code per PR (excluding generated files). Larger changes get split into stacked diffs. Stack with worktrees, not branch-switching:

git fetch origin && git switch dev && git pull --ff-only
mkdir -p ../wt
git worktree add -b feat/a ../wt/a dev
git worktree add -b feat/b ../wt/b feat/a    # stacked on feat/a

After feat/a merges, rebase downstream branches:

git -C ../wt/b fetch origin && git -C ../wt/b rebase origin/dev

Conventional Commits

type(scope): description. Type is feat, fix, refactor, docs, test, chore. Imperative mood, lowercase, no period, ≤72 chars.

feat(auth): add org-level permissions
fix(billing): handle zero-balance edge case
refactor(api): extract validation to middleware

Never use "and" in a commit message. If you need "and", you're describing two changes that should be two commits. Split them.

Force pushes

After a rebase, use --force-with-lease, never --force. Never force-push to main/master.

Heredoc for multi-line commit messages

git commit -m "$(cat <<'EOF'
type(scope): one-liner subject

Optional body explaining why, not what.

Refs #123
EOF
)"

Pre-commit checklist

1. git status -sb -- review staged + unstaged changes.
2. git diff -- eyeball every hunk.
3. git add -p -- stage precisely; split unrelated hunks across commits.
4. pnpm typecheck && pnpm lint && pnpm test (or the project's equivalent).
5. git commit -m "..." -- Conventional, ≤72 chars.

Never

• --no-verify, --no-gpg-sign (unless explicitly requested).
• git rebase -i from a tool call (interactive, will hang).
• --amend once pushed (unless explicitly requested + force-with-lease).
• git config updates from a tool call.
