The pipeline is the product team's contract with production: every commit that passes is a candidate release, and the pipeline enforces that contract automatically. --- ## When to use this skill Trigger this skill when the user: - Creates or modifies a GitHub Actions, GitLab CI, or Jenkins pipeline - Implements PR checks, branch protection rules, or required status checks - Sets up deployment environments (staging, production) with promotion gates - Implements blue-green, canary, rolling, or recreate deployment strategies - Configures caching for dependencies or build artifacts to speed up pipelines - Sets up matrix builds to test across multiple Node versions or operating systems - Automates secrets injection, environment promotion, or rollback procedures - Diagnoses a slow pipeline and needs to find what to parallelize or cache Do NOT trigger this skill for: - Infrastructure provisioning from scratch (use a Terraform/Kubernetes skill instead) -...
