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 linking is left to chance. This Skill provides a structured workflow for designing page hierarchies, navigation systems, URL patterns, and internal linking plans that work for both users and search engines. ## Core Features & Use Cases - Page Hierarchy Design: Produces ASCII tree structures and Mermaid visual sitemaps applying the 3-click rule and flat-vs-deep tradeoffs, with templates for SaaS, blog, e-commerce, docs, hybrid, and small business sites. - Navigation & URL Specification: Defines header, footer, sidebar, and breadcrumb navigation with concrete rules (4-7 header items, CTA placement), plus consistent URL patterns per page type and redirect guidance for restructures. - Internal Linking Strategy: Builds hub-and-spoke content models, orphan page audits, and cross-section linking plans, with page-purpose recipes for blogs, portfolios, services, docs, and resource hubs. - Use Case: A SaaS team adding 200 integration pages and 50 comparison pages asks how they fit the site. The Skill recommends hub pages at /integrations and /compare, keeps them out of the main nav, applies hub-and-spoke linking, and delivers a full URL map and navigation spec. ## Quick Start Ask the agent to plan the site architecture for your website, describing your site type, existing or planned pages, and whether it is a new build or a restructure.
