Skill UI

A comprehensive guide for building production-quality, highly accessible, and responsive user interfaces. Covers advanced topics including component architecture (composition over configuration), robust state management patterns (Context, Redux, Server State), adherence to design systems, and meeting WCAG accessibility standards. Use this skill when developing or refining complex user-facing components that require professional polish and maintainability.

A general-purpose skill for writing and executing end-to-end (E2E) browser automation tests using Playwright. It handles complex scenarios such as login flows, form submission, responsive viewport testing, and checking for broken links. The skill automatically detects local development servers and executes custom scripts in a safe, temporary directory, providing real-time debugging and results visualization.

This tool performs a comprehensive audit of website images to ensure optimal SEO and web performance. It checks for proper alt text descriptions, recommends modern formats (WebP, AVIF), validates file sizes, and verifies responsive image implementation using `srcset` and `sizes`. Furthermore, it guides best practices for lazy loading, prioritizing LCP images, and preventing Cumulative Layout Shift (CLS) by checking for dimensions.

This skill provides a comprehensive review of UI components and codebases to ensure strict adherence to established design systems, accessibility guidelines (WCAG), and modern front-end best practices. It checks for design token compliance (e.g., semantic colors, scaled spacing), component conventions, WCAG accessibility standards (a11y), mobile responsiveness, and visual coherence across the entire application.

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.

A comprehensive guide to optimizing CAST AI's core performance metrics, including node provisioning speed, autoscaler responsiveness, and API call efficiency. This skill covers techniques like configuring headroom, selecting optimal instance families, tuning evictors, and implementing caching for multi-cluster dashboards to ensure high availability and cost efficiency in cloud environments.

This guide addresses the performance degradation when automating Apple Notes, especially with large note collections (10,000+). It details architectural patterns, caching strategies, and scripting best practices (like batch processing and incremental sync) to prevent bottlenecks caused by excessive IPC calls, ensuring automation remains responsive at scale.

A comprehensive guide to optimizing the Finta fundraise workflow. This document addresses critical performance bottlenecks, including pagination issues with large investor datasets, latency in multi-stage round data aggregation, and slow CRM synchronization. Optimization strategies cover cursor-based fetching, strategic caching (TTL management), connection pooling, and robust rate limit handling, aiming to reduce pipeline load times by 50-70% and maintain dashboard responsiveness.

Collects comprehensive diagnostics from an unresponsive Oracle Cloud Infrastructure (OCI) compute instance. This tool gathers critical data—including serial console logs, cloud-init logs, VCN flow logs, and CPU metrics—into a single, self-contained tar archive. Use this when an instance is failing, stuck in provisioning, or showing underlying infrastructure errors, providing support teams with all necessary information for root-cause analysis.

This skill guides developers through advanced techniques to optimize Shopify store performance and improve Core Web Vitals (LCP, CLS, INP). It covers fixing lazy-loaded hero images, migrating to the modern `image_url` filter for responsive images, profiling slow Liquid renders, and optimizing font delivery, ensuring a fast and professional e-commerce experience.

This comprehensive skill serves as an entry point for all web UI design needs, covering components, pages, dashboards, and advanced layouts using React, Vue, or pure HTML/CSS. It addresses not only aesthetics and polish (color, typography, spacing) but also deep structural concerns like responsive design, UX auditing, and visual system implementation. Use it whenever a user asks to improve the look, feel, or function of a digital interface.

This skill generates a comprehensive spacing and layout token system for Figma. It establishes foundational design rules, including a scalable spacing scale (e.g., 4px/8px base), responsive grid definitions for various breakpoints, and component-specific spacing conventions. It ensures design consistency and provides clear guidelines for developer handoff.
