claude-pilot: Skill for Claude Code

SKILL: Git Operations

Purpose: Safe push/pull/merge operations with retry logic and error handling Target: All git operations

---

Quick Start

When to Use This Skill

• Pushing changes to remote
• Pulling latest changes
• Merging branches
• Resolving merge conflicts

Quick Reference

# Push with retry (3 attempts, 2s delay)
git_push_with_retry() {
  local branch="${1:-$(git rev-parse --abbrev-ref HEAD)}"
  for attempt in {1..3}; do
    git push origin "$branch" 2>&1 && return 0
    echo "Retry $attempt/3..." && sleep 2
  done
  return 1
}

# Pull with fast-forward only
git pull --ff-only || echo "Manual merge required"

Core Operations

Push with Retry

Purpose: Handle transient network failures with exponential backoff (3 attempts, 2s/4s/8s delay)

git_push_with_retry() {
  local remote="${1:-origin}"
  local branch="${2:-$(git rev-parse --abbrev-ref HEAD)}"
  local max_attempts=3
  local wait_times=(2 4 8)  # Exponential backoff

  echo "🔄 Pushing to $remote/$branch..."

  for attempt in $(seq 1 $max_attempts); do
    # Attempt push
    if git push "$remote" "$branch" 2>&1; then
      echo "✓ Push successful"
      return 0
    fi

    local exit_code=$?
    local error_output="$(git push "$remote" "$branch" 2>&1 || true)"

    # Classify error
    if echo "$error_output" | grep -qiE "non-fast-forward|rejected|protected"; then
      echo "❌ Push rejected (non-fast-forward or protected branch)"
      echo "   Run: git pull --rebase && git push"
      return 1
    elif echo "$error_output" | grep -qiE "authentication|permission|credentials"; then
      echo "❌ Authentication error"
      echo "   Check git credentials: git config --list | grep credential"
      return 1
    fi

    # Retry for network/transient errors
    if [ $attempt -lt $max_attempts ]; then
      local wait_time=${wait_times[$((attempt-1))]}
      echo "⚠️  Push failed (attempt $attempt/$max_attempts), retrying in ${wait_time}s..."
      sleep "$wait_time"
    else
      echo "❌ Push failed after $max_attempts attempts"
      return 1
    fi
  done

  return 1
