Plan and execute design validation through prototyping strategies, usability testing, heuristic evaluation, and A/B experiments.
Design & UX skills: UX Research Plan, Design Critique, Accessibility Audit. Create research plans with discussion guides, critique designs using JTBD and Gestalt principles, and audit for WCAG 2.2 compliance.
User-centered design and product excellence. Master user research, UX design, accessibility, product strategy, user journey mapping, and inclusive design practices.
Use this agent when conducting user research, analyzing user behavior, creating journey maps, or validating design decisions through testing. This agent specializes in understanding user needs, pain points, and behaviors to inform product decisions within rapid development cycles. Examples:\n\n<example>\nContext: Understanding user needs for a new feature
User research skills for designers: personas, empathy maps, journey maps, interview scripts, usability testing, and card sorting.
Design workflow for coding agents: discovery, research, strategy, inclusive design, critique, and handoff — enforced automatically
Establish architecture governance, design fitness functions, manage tech debt, and ensure compliance. Build sustainable architecture practices.
QA skills for accessibility-testing domain.
QA skills for api-testing domain.
Master architecture communication: C4 models, RFCs, presentations, and documentation. Align stakeholders and explain architectural decisions.
Product vision, strategy, positioning, and go-to-market planning.
