GitLab CI/CD knowledge base (GitLab 18+). Use whenever the user asks about, needs an explanation of, writes, reviews, optimizes, or debugs GitLab pipelines or .gitlab-ci.yml files: stages, jobs, rules and workflows, includes and templates, caching and artifacts, child and downstream pipelines, environments and deployments, or bash scripts running inside CI jobs, even if they only mention "pipeline" or "CI" in a GitLab context. Covers pipeline structure and refactoring, large or unreadable pipeline graphs, CI/CD best practices, debugging failed pipelines, CI security, and DevOps automation on GitLab.
