Github Actions Templates

Generates production-ready GitHub Actions workflows with proper security scanning, matrix builds, and deployment pipelines. Covers the patterns most teams actually need: test automation across multiple Node/Python versions, Docker image builds with GHCR, Kubernetes deployments with approval gates, and vulnerability scanning with Trivy. The templates include proper caching, specific action versions, and reusable workflows to avoid copy-paste sprawl. Honestly, this handles about 90% of CI/CD scenarios you'll encounter, from basic PR checks to full production deployments with Slack notifications.
