What problem does it solve? Before any visual design begins, teams need a clear structural blueprint of the product: what pages exist, how users navigate between them, and which content matters most. This Skill produces that blueprint as a structured information architecture document, preventing navigation chaos and scope confusion later in design and development. ## Core Features & Use Cases - Sitemap and Navigation Design: Generates a page tree, global navigation (primary, secondary, utility), and content hierarchy with P1/P2/P3 priorities. - Key User Flows: Maps critical flows from entry to result, including unauthenticated access and empty/loading/error states. - Optional Journey Maps: On request, adds a Mermaid-based journey map section for a single persona and flow, scoring each step 1-5 to surface friction points and prioritized recommendations. - Use Case: Given a product brief for a booking service, produce an IA document covering the sitemap, the "first booking" flow, and navigation priorities before any wireframing starts. ## Quick Start Ask the assistant to design the information architecture for your product based on the existing brief, including a sitemap, global navigation, and the key user flows.
