Skill UI

This comprehensive skill provides a full workflow for creating high-quality, annotated animated GIFs and screen recordings. It supports capturing multi-step UI interactions using Playwright, assembling dynamic GIFs with imageio, applying variable frame timing, and adding sophisticated annotations (including fade-in effects) for clear documentation, pull request descriptions, or release note demos.

This skill implements the Karpathy LLM-wiki principle by automatically enriching research paper wiki pages. When papers are ingested as bare scaffolds with many '_TODO._' placeholders, this tool fetches content from multiple external sources (e.g., ArXiv, AlphaXiv) and rewrites these placeholders into detailed, coherent prose summaries. It is essential for transforming raw scaffolds into maintainable, knowledge-rich wiki entries, allowing the LLM to maintain the knowledge base.
