What problem does it solve? Planning or restructuring a website's information architecture is hard to do systematically: pages get buried, navigation becomes cluttered, URLs grow inconsistent, and internal links are left to chance. This Skill provides a structured method for designing page hierarchies, navigation systems, URL patterns, and internal linking strategies that work for both users and search engines. ## Core Features & Use Cases - Page Hierarchy Design: Apply the 3-click rule and flat-vs-deep tradeoffs to produce ASCII tree structures and Mermaid visual sitemaps for any site type (SaaS, blog, e-commerce, docs, hybrid, small business). - Navigation & URL Specification: Define header nav (4-7 items), footer columns, breadcrumbs, and consistent URL patterns per page type, with redirect guidance for restructures. - Internal Linking Strategy: Build hub-and-spoke content models, audit orphan pages, and plan cross-section links. - Use Case: A SaaS team adding 200 programmatic integration pages asks how they fit into the site; the Skill recommends hub pages at /integrations, keeps them out of the main nav, and defines the linking model. ## Quick Start Ask the agent to plan the site architecture for your website, describing your site type, main sections, and whether it is a new build or a restructure.
