ABC Git Flow is a comprehensive Git workflow extension designed to manage complex branch structures across multiple environments, including production, gray (canary), pre-release (rc), and development. It automates feature and hotfix branch lifecycle management, handles standardized tagging for CI/CD pipelines, and facilitates Merge Request creation with integrated review notifications. This skill is essential for developers working within the ABC ecosystem to ensure consistent branch naming, rebase hygiene, and smooth multi-stage deployments from feature inception to final production release.
