Conduct heuristic evaluation of user interfaces using Nielsen's 10 usability principles. Use this skill when the user needs to audit a website, app, or interface for usability issues, prioritize UX improvements, or conduct a quick expert review without user testing — even if they say 'review this UI', 'find usability problems', or 'why do users struggle with our app'.
Deep-dive usability evaluation of specific user tasks. Simulates novice user cognition step-by-step to identify learnability issues, unclear actions, and points of confusion.
Research methodologies, user interviews, surveys, usability testing, persona creation, and insight extraction
Expert UX research covering user research methods, usability testing, data synthesis, and research operations.
Evaluate designs for usability, visual hierarchy, consistency, and adherence to design principles. Trigger with "what do you think of this design", "give me feedback on", "critique this", "review this mockup", or when the user shares a design and asks for opinions.
Use when reviewing an agent skill, SKILL.md package, or skill-like instruction document for design quality, missing patterns, portability, or agent usability before adoption or revision
Design user interactions, flows, and interface behaviors. Use for wireframes, prototypes, micro-interactions, user flows, state machines, affordance design, and usability reviews. Covers IxD principles, Nielsen heuristics, Fitts's Law, Hick's Law, and emerging paradigms (spatial, conversational, gesture-based interfaces). Keywords: IxD, wireframe, prototype, user flow, micro-interaction, UI state diagram, screen flow, clickable prototype, interaction pattern.
User personas, customer journey maps, interview guides, usability testing, and card sorting. Use when building user understanding, mapping customer experiences, planning user research sessions, or defining Jobs-to-Be-Done.
Adapt interfaces for different devices, breakpoints, platforms, and usage contexts without sacrificing core usability.
Evaluate UI/flows from cognitive load, error prevention, and accessibility perspectives. Apply when reviewing UX, discussing user confusion, high drop-off, or form usability issues.
Apply cognitive science and HCI research to design decisions. Use when you need the scientific 'why' behind usability, explaining user behavior, understanding perception/memory/attention limits, evaluating cognitive load, assessing mental model alignment, predicting performance with Fitts's/Hick's Law, or grounding interface decisions in research rather than opinion.
Systematic usability evaluation using established heuristics (Nielsen's 10, Shneiderman's 8, or custom rubrics). Use when reviewing UI designs, screenshots, prototypes, or live products for usability issues. Triggers on "review this design", "what's wrong with this UI", "usability check", "evaluate this interface", or when user shares screenshots/mockups asking for feedback.
