What is product-challenger?
A skeptical product advisor that challenges requirements and designs UI/UX solutions using first-principles thinking. Use when user wants to (1) review requirements, analyze features, validate product decisions, evaluate PRDs, or question if a feature is worth building, OR (2) design UI/UX for a feature with Notion-style minimalist approach. Helps identify fake requirements through evidence-based challenges, and provides interaction flows, layouts, and wireframes. Source: guangtouwangba/weaver.
