What problem does it solve? Before any wireframe or design system is produced, teams need to know what visual and interaction conventions the industry has already documented and what accessibility criteria actually bind. This Skill mines that documented prior art from governed sources and produces schema-validated artifacts a downstream design skill can consume, instead of relying on an agent's recall or screenshot galleries. ## Core Features & Use Cases - Vocabulary map derivation: Builds a UI-pattern vocabulary map across five axes (component, pattern, screen-archetype, platform-context, design-system) with typed expansions and honest provenance. - Angle-based search execution: Runs one named search angle across design-system documentation, the ARIA Authoring Practices Guide, WCAG success criteria, platform HIGs, and the deceptive-pattern corpus, recording every query verbatim with a coverage grid. - Deep-read extraction and synthesis: Deep-reads one convention source into a structured record carrying DTCG design tokens verbatim, then synthesizes a convention register and seven-section report. - Use Case: Before designing a consumer marketplace app, run the survey to extract the WCAG 2.2 AA criteria, ARIA interaction contracts, and relevant design-system conventions that bind the project, then hand the register to the downstream design-system authoring skill. ## Quick Start Use visual-prior-art-survey to build the UI-pattern vocabulary map for my product scope before any wireframing begins.
