Use when organizing content for digital products, designing navigation systems, restructuring information hierarchies, improving findability, creating taxonomies or metadata schemas, or when users mention information architecture, IA, sitemap, navigation design, content structure, card sorting, tree testing, taxonomy, findability, or need help making information discoverable and usable.
Conduct expert heuristic evaluations using Nielsen's heuristics and domain-specific criteria.
Fundamental design principles based on Don Norman's "The Design of Everyday Things". Use when you need to: (1) design affordances and signifiers into interfaces, (2) analyze why products are confusing, (3) apply constraints to prevent errors, (4) design clear feedback mechanisms, (5) bridge gulfs of execution and evaluation, (6) create intuitive conceptual models, (7) apply human-centered design, (8) understand why users make errors and design fault-tolerant systems.
Evaluates interfaces, components, screens, and flows against universal UX/UI principles (heuristics, UX laws, Gestalt, cognitive psychology, accessibility) and delivers concrete, prioritized improvements. Use whenever the user shares UI code, screenshots, components, or mockups and wants feedback — even if they don't use the words "critique" or "review". Also trigger when the user asks "what's wrong with this UI", "how can I improve this", "review my component", "does this look right", "give me feedback on this design", or shares any interface and asks for thoughts. Trigger for partial slices too (a single button, form, or card) — not only full screens.
Evaluate interface descriptions against 168 research-backed UX/UI principles. Returns structured findings with severity, remediation, and business impact. API key optional — enriched output requires uxuiprinciples.com API Access.
Evaluate UX/UI using Don Norman's 7 fundamental design principles from The Design of Everyday Things. Audit discoverability, affordances, signifiers, feedback, mapping, constraints and conceptual models.
Evaluate and improve user experience of interfaces (CLI, web, mobile)
You are **UX Researcher**, an expert user experience researcher who specializes in understanding user behavior, validating design decisions, and providing actionable insights. You bridge the gap be...
Design experiences that optimize mental resources using Cognitive Load Theory. Use when designing interfaces, creating onboarding flows, planning information architecture, or improving task completion rates.
Plan, conduct, and synthesize user research. Trigger with "user research plan", "interview guide", "usability test", "survey design", "research questions", or when the user needs help with any aspect of understanding their users through research.
UX laws and cognitive psychology principles for designing better interfaces
Design click/first-click tests to evaluate navigation and information findability.
