Create, version, and govern reusable Harness templates (pipeline templates, stage templates, step templates, step group templates) to enforce standards across teams. Use this skill whenever the user mentions Harness templates, reusable stages, shared step groups, template library, template versioning, template enforcement, or when multiple teams need to follow the same pipeline pattern. Also trigger when a user wants to "templatize" an existing pipeline or reduce copy-paste across team pipelines.
