List Layout guides an agent through designing, optimizing, and auditing vertical and stacked content displays like blog indexes, documentation, and search results. It helps determine whether a list or grid is appropriate, structures individual items with titles, metadata, and excerpts, and outlines variants including simple, rich, table-like, and thumbnail lists. Reach for this skill when the user needs to establish scannable, text-heavy content layouts adhering to F-pattern reading and responsive best practices.
