Inspects live or staging websites to spot layout, responsive, and accessibility issues, then traces those problems to source files for targeted fixes, making it ideal for developers and designers reviewing static sites, SPAs, or full-stack apps.

This expert skill audits and designs user interfaces for the Apple ecosystem (iOS, macOS, watchOS, visionOS) against the official Human Interface Guidelines (HIG). It checks crucial elements like contrast ratios (WCAG standards), minimum tap-target sizes, and adherence to modern design languages like Liquid Glass. Use it when reviewing mockups or developing native-feeling Apple apps to ensure accessibility and optimal user experience.

An elite skill dedicated to generating premium, app-native, and highly readable UI/UX concept images. It visualizes entire application flows—from onboarding and authentication to complex dashboards—for iOS, Android, and cross-platform products. The focus is on creating believable, highly intentional designs with strong consistency, controlled color palettes, and clean hierarchies, avoiding generic, default-style mockups.

This powerful script uses Nano Banana models to facilitate advanced image creation and manipulation. Users can generate high-quality images from simple text prompts, perform detailed image edits (inpainting/outpainting), or combine multiple images into a single collage. It supports various resolutions and aspect ratios, making it ideal for artists, designers, and anyone requiring advanced visual content generation.

This advanced skill is designed to generate high-quality, publication-ready academic illustrations and diagrams. It utilizes a sophisticated, multi-stage iterative workflow involving Claude for planning, layout optimization, and strict visual review, combined with a dedicated local Codex app-server bridge for native image rendering. The process ensures that generated figures meet the rigorous aesthetic and structural standards required for top-tier conferences and journals (e.g., CVPR, NeurIPS).
