This reviewer analyzes interfaces across CLI, web, and mobile apps, then documents findings in a structured markdown file following Nielsen's heuristics and WCAG guidelines. It covers the full spectrum from visual hierarchy to accessibility compliance, with platform-specific considerations like terminal color schemes for CLIs or touch target sizing for mobile. The output format is methodical, breaking issues into critical/high/medium/low priority with specific before/after recommendations and implementation notes. What I appreciate here is the emphasis on actionable specifics over vague design feedback. It's positioned as a senior UX expert voice, which means you get opinionated analysis rather than just a checklist, though it still maintains enough structure to be useful for tracking and prioritization.
