Skill UI

A comprehensive collection of agent skills for rigorously auditing digital interfaces and user flows. It evaluates designs against 168 research-backed UX/UI principles, detects common design antipatterns, and provides specialized review for AI-powered interfaces, ensuring adherence to modern best practices.

Generate professional, master-level designs in the unique Mondo aesthetic. This skill is perfect for creating stunning posters, book covers, album art, and event promotion materials for various platforms (e.g., 9:16, 1:1, 21:9). It removes the need for graphic design expertise by automatically optimizing prompts, simulating limited color palettes (screen print), and applying advanced compositional techniques like negative space storytelling and dramatic scale contrast.

StyleSeed is a comprehensive design judgment engine designed to elevate the aesthetic quality of AI-generated user interfaces. It codifies 69 visual rules covering color discipline, spatial rhythm, information hierarchy, and motion feedback. By integrating these principles, developers can ensure that AI output looks professionally designed and polished, rather than simply generated. Includes React components, Tailwind CSS implementation, and actionable design guidelines.

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.

This utility burns an SRT subtitle track directly into an MP4 video file using ffmpeg's libass filter. It re-encodes the video (H.264) while copying the audio untouched. It supports defining custom font fallback chains (e.g., CJK fonts) and provides detailed control over font size, margins, and video encoding parameters (CRF, preset) for professional subtitling workflows.

An open-source, advanced tool for professional post-production of screen recordings.
