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 design, URL structure, and internal linking. ## Core Features & Use Cases - Page Hierarchy Design: Generates ASCII tree structures and Mermaid visual sitemaps applying the 3-click rule and flat-vs-deep principles, with templates for SaaS, blog, e-commerce, docs, hybrid, and small business sites. - Navigation & URL Specification: Defines header, footer, sidebar, and breadcrumb navigation patterns plus consistent, SEO-friendly URL patterns for every page type. - Internal Linking Strategy: Builds hub-and-spoke linking models, orphan page audits, and cross-section link plans. - Use Case: A SaaS team adding 200 integration pages and 50 comparison pages asks how they fit into the site; the Skill recommends hub pages, URL patterns, and a hub-and-spoke linking plan without cluttering the main nav. ## Quick Start Ask the assistant to plan the site architecture for your website, describing your site type, main pages, and goals.
