What problem does it solve? Planning or restructuring a website's information architecture is difficult: pages get buried, navigation becomes cluttered, URLs grow inconsistent, and internal linking is neglected. This Skill produces a complete site architecture plan covering page hierarchy, navigation, URL structure, and internal linking. ## Core Features & Use Cases - Page Hierarchy Design: Applies the 3-click rule and flat-vs-deep tradeoffs to produce ASCII tree hierarchies and Mermaid visual sitemaps with navigation zones. - URL Structure & Navigation Specs: Defines readable URL patterns per page type, header/footer/sidebar navigation rules, and breadcrumb alignment with schema markup guidance. - Internal Linking Strategy: Builds hub-and-spoke content models, orphan page audits, and cross-section linking plans. - Use Case: A SaaS company adding 200 integration pages and 50 comparison pages asks how they fit into the site. The Skill recommends hub pages at /integrations and /compare, keeps them out of the main nav, and maps the hub-and-spoke linking model. ## Quick Start Ask the assistant to plan the site architecture for your website, describing your site type, existing pages, and goals.
