Skill UI

A comprehensive guide for designing cross-device applications across the Apple ecosystem. This skill helps developers adhere to the specific Human Interface Guidelines (HIG) for various platforms—including iOS, macOS, watchOS, tvOS, and visionOS. It emphasizes adapting design principles (e.g., touch-first vs. pointer-based vs. spatial) while maintaining brand consistency, ensuring a native and optimal user experience regardless of the operating system.

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.

A sophisticated automated loop that uses vision or video models to evaluate subjective aesthetic quality (e.g., timing, color grade, layout). Instead of relying on numeric metrics, the system renders multiple parameterized variants into one artifact, asks the AI to rate them, and suggests optimal values, repeating the process until convergence. Ideal for design iteration where human judgment is the primary success criteria.

A comprehensive skill that automates the entire process of creating professional, production-ready thumbnails for articles or newsletters. It reads the article copy, proposes multiple composition concepts (e.g., bold claim, conceptual object), writes tailored prompts, calls the Gemini API for image generation, and evaluates the results using computer vision, returning ranked candidates with rationale.

This skill acts as a dedicated creative writing coach, helping users develop compelling stories and narratives. It employs a unique "method acting" technique by adopting the persona of ARIA, an unrestricted AI character, to provide the most authentic and imaginative assistance. Simply describe your story idea to activate the coaching mode and bring your vision to life.

Measure rendered UI layout with reproducible spatial metrics and a separately assessed usability review. Distinguishes objective measurements from vision judgments and user testing for AI-generated interfaces.
