Skill UI

This skill generates highly disciplined, forceful, and timeless English prose, specifically designed to bypass modern AI writing clichés and filler language. It is ideal for essays, literary rewrites, or demanding analytical writing that requires sharp, concrete, and confident phrasing. It enforces strict rules against common AI cadences, therapeutic fluff, and vague transitions, ensuring the output is muscular and substantive.

Transforms natural-language prompts into Excalidraw JSON diagrams, supporting flowcharts, relationships, mind maps, architecture, DFD, swimlane, class, sequence, and ER views; ideal when users ask to visualize processes or system structures and need editable Excalidraw files.

This comprehensive guide outlines world-class product design principles, mimicking Apple's standard. It covers building robust design systems, defining essential design tokens (color, typography, spacing, motion), structuring UI components (atoms to organisms), optimizing UX flows, and designing engaging onboarding experiences. Ideal for product designers and PMs needing to establish a cohesive, scalable visual language and improve overall user experience.

This skill transforms written content, such as articles and reports, into engaging, two-host conversational podcast audio. It first structures the content into a detailed JSON script (dialogue format) and then uses advanced Text-to-Speech synthesis to generate the final MP3 file. Supports both English and Chinese languages, making content accessible for audio-only listening.

Generates Excalidraw diagrams from natural language prompts, covering flowcharts, relationship maps, mind maps, architecture, data flow, swimlane, class, sequence, and ER diagrams for communicating processes and systems.

Generate publication-quality scientific diagrams from natural-language descriptions using Nano Banana 2 AI, with Gemini quality review and smart iteration until your document-type threshold is met. Ideal for neural network architectures, flowcharts, pathways, and posters.

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.

This skill acts as an expert Design Systems Lead, analyzing complex technical assets (HTML, CSS, screenshots) from existing projects. It synthesizes a comprehensive 'Semantic Design System' into a structured DESIGN.md file. This output serves as the authoritative 'source of truth' for AI prompting, ensuring that any new UI generated by tools like Stitch adheres perfectly to the established visual language, color palette, and component standards.

An expert guideline for authoring comprehensive, implementation-ready design systems. This skill defines a vibrant, playful, and structured UI language, covering foundational tokens (color, typography, spacing), component anatomy, and WCAG 2.2 AA accessibility standards. It ensures consistency and clarity for engineers and designers.

This skill acts as an expert guide for authoring comprehensive, implementation-ready design system documentation. It structures guidelines covering foundational design tokens (color, spacing, typography), detailed component anatomy, interaction states, and WCAG accessibility standards. Ideal for product designers and engineers needing to define a cohesive and scalable UI language.

Generate unique, 16:9 hand-drawn illustrations for articles, blog posts, and technical documentation. This skill translates abstract cognitive anchor points into clean, absurd, and memorable whiteboard sketches. It features a consistent, recurring character, 'Grav,' who actively drives the narrative, ensuring a unique and professional visual language across all your content.

Manages the entire lifecycle of design systems within the Stitch platform. This powerful skill allows users to retrieve project assets, synthesize design tokens (DESIGN.md) from existing screens or descriptions, create/update the system in Stitch, and finally apply these tokens consistently across multiple screens to ensure a unified and scalable brand language.
