rollback

User Input

$ARGUMENTS

Goal

Safely rollback a feature that failed or is no longer wanted, including:

1. Reverting all code changes since branch creation
2. Cleaning up feature artifacts (spec.md, plan.md, tasks.md)
3. Optionally deleting the feature branch
4. Switching back to the parent branch

Provides two rollback strategies with comprehensive safety checks.

Execution Steps

Step 1: Safety Checks

echo "🔍 Performing safety checks..."
echo ""

# Check 1: Get current branch
CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD 2>/dev/null)

if [ -z "$CURRENT_BRANCH" ]; then
  echo "❌ Error: Not in a git repository"
  exit 1
fi

# Check 2: Prevent rollback of main/master/develop
PROTECTED_BRANCHES=("main" "master" "develop" "production")

for protected in "${PROTECTED_BRANCHES[@]}"; do
  if [ "$CURRENT_BRANCH" = "$protected" ]; then
    echo "❌ Error: Cannot rollback protected branch '$CURRENT_BRANCH'"
    echo ""
    echo "💡 Rollback is designed for feature branches only."
    echo "   If you need to revert changes on $CURRENT_BRANCH, use:"
    echo "   git revert <commit-hash>"
    exit 1
  fi
done

# Check 3: Check for uncommitted changes
DIRTY=$(git status --porcelain 2>/dev/null)

if [ -n "$DIRTY" ]; then
  echo "❌ Error: Uncommitted changes detected"
  echo ""
  echo "You have uncommitted changes. Please commit or stash them first:"
  git status --short
  echo ""
  echo "To commit:"
  echo "  git add ."
  echo "  git commit -m \"WIP: save before rollback\""
  echo ""
  echo "To stash:"
  echo "  git stash push -m \"Before rollback\""
  exit 1
fi

# Check 4: Detect parent branch
# First try git config
PARENT_BRANCH=$(git config "branch.$CURRENT_BRANCH.parent" 2>/dev/null)

# Fallback to common parent branches
if [ -z "$PARENT_BRANCH" ]; then
  for candidate in "develop" "development" "dev" "main" "master"; do
    if git show-ref --verify --quiet "refs/heads/$candidate"; then
      PARENT_BRANCH="$candidate"
      break
    fi
  done
fi

# Last resort: ask user
if [ -z "$PARENT_BRANCH" ]; then
  echo "⚠️  Could not auto-detect parent branch"
  PARENT_BRANCH="main"  # default
fi

echo "✅ Safety checks passed"
