What problem does it solve? Growing websites often end up with disorganized page structures, confusing navigation, and inconsistent URLs that hurt both user experience and SEO. This Skill provides a structured methodology for planning or restructuring a site's information architecture. ## Core Features & Use Cases - Page Hierarchy Design: Builds ASCII tree structures and Mermaid visual sitemaps applying the 3-click rule and flat-vs-deep principles, with templates for SaaS, e-commerce, blog, docs, and small business sites. - Navigation & URL Planning: Defines header/footer/sidebar navigation specs, breadcrumb patterns, and consistent URL conventions for every page type. - Internal Linking Strategy: Implements hub-and-spoke content models, orphan page audits, and cross-section linking plans. - Use Case: A SaaS company adding 200 programmatic integration pages asks how they fit into the site; the Skill recommends hub pages, URL patterns, and linking rules without cluttering the main nav. ## Quick Start Ask the assistant to plan the site architecture for your website, describing your site type, main sections, and whether it is a new build or a restructure.
