Branch — Create Feature Branch

Create a feature branch from the default branch with a descriptive, conventional name.

Do NOT ask for permission. Create the branch and push it.

---

Step 1 — Detect default branch

PROJECT_ROOT=$(git rev-parse --show-toplevel)
cd "$PROJECT_ROOT"
DEFAULT_BRANCH=$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@')
DEFAULT_BRANCH="${DEFAULT_BRANCH:-main}"
CURRENT_BRANCH=$(git branch --show-current)
echo "Default branch: $DEFAULT_BRANCH"
echo "Current branch: $CURRENT_BRANCH"

If not on the default branch, warn:

⚠️ Currently on '$CURRENT_BRANCH', not '$DEFAULT_BRANCH'.
Creating branch from current HEAD. Proceed only if intentional.

---

Step 2 — Pull latest

git fetch origin
git checkout "$DEFAULT_BRANCH"
git pull origin "$DEFAULT_BRANCH"

---

Step 3 — Generate branch name

Derive a branch name from the task description using conventional prefixes:

Prefix	Use when
feat/	New feature
fix/	Bug fix
chore/	Maintenance, deps, config
refactor/	Code restructuring
docs/	Documentation only
test/	Test additions or fixes

Naming rules:

• Lowercase, hyphen-separated: feat/add-user-auth
• Max 50 characters for the slug portion
• No special characters beyond hyphens
• Derived from the task description or user input

Examples:

"Add user authentication"         → feat/add-user-auth
"Fix login timeout bug"           → fix/login-timeout
"Update dependencies"             → chore/update-deps
"Refactor payment module"         → refactor/payment-module
"Add API documentation"           → docs/api-docs

---

Step 4 — Create and push branch

BRANCH_NAME="<prefix>/<slug>"
git checkout -b "$BRANCH_NAME"
git push -u origin "$BRANCH_NAME"

If the branch already exists locally or remotely:

git checkout "$BRANCH_NAME"
git pull origin "$BRANCH_NAME" 2>/dev/null || true
