Skill UI

RDKit delivers a Python-based cheminformatics toolkit for parsing SMILES/SDF, computing descriptors, generating 2D/3D coordinates, fingerprinting, searching substructures, managing reactions, and visualizing molecules, ideal for drug discovery and computational chemistry workflows.

Query the Reactome Content and Analysis Services (or the reactome2py client) to fetch pathway hierarchies, map genes, run overrepresentation/expression analyses, and explore disease interactions for systems biology research.

Guides building and scaling Convex backends with TypeScript schemas, queries, mutations, real-time subscriptions, auth, file storage, scheduling, and deployment across React, Next.js, Angular, Vue, Svelte, and RN.

This skill provides a comprehensive framework for performing end-to-end UI testing and verification on Android emulators. It guides users through systematic processes including device calibration, UI element discovery using uiautomator, performing complex interactions (tap, swipe, input), and robust reporting via visual screenshots and logcat analysis. Ideal for ensuring the stability and functional correctness of React Native or native Android applications.

A comprehensive development tool for building and managing enterprise-grade transactional email systems. It supports modern React Email and MJML templates, generating production-ready code for major providers like Resend, Postmark, and SendGrid. Key features include multi-provider integration, internationalization (i18n), dark mode, spam score optimization, and advanced analytics tracking. Ideal for setting up new products or migrating legacy email infrastructure.

Generates high-converting landing pages as ready-to-use Next.js/React TSX components with Tailwind CSS, proven copy frameworks, SEO meta, structured data, and Core Web Vitals targets for marketing campaigns, A/B tests, or conversion-focused sites.

Provides guidance for AWS Serverless EDA, outlining how to build event-driven workflows using AWS services like Lambda, EventBridge, and DynamoDB so teams can react to changes without managing servers.

This skill enforces a strict, opinionated baseline for UI development in Tailwind CSS projects. It ensures adherence to best practices concerning accessibility (ARIA), motion, typography, and layout structure. Use it when building complex UI components, reviewing CSS utilities, or preventing sloppy, generic interface design, especially when mitigating potential issues from AI-generated code.

This comprehensive guide details the process of setting up Tailwind CSS v4 within an Expo React Native project. It ensures universal styling compatibility across iOS, Android, and Web by utilizing react-native-css and NativeWind v5. The setup covers required configurations for Metro, PostCSS, global CSS, and even provides reusable styled components for optimal development experience.

This skill guides developers on using the `@expo/ui/swift-ui` package to integrate native SwiftUI views and modifiers into Expo applications. It is essential for building authentic, platform-specific iOS user interfaces within a cross-platform React Native context, especially when targeting Expo SDK 55. Learn how to wrap SwiftUI trees and embed React Native components.

Master robust and type-safe patterns for React development using fp-ts. This guide covers managing state with Option, sophisticated form validation using Either (collecting all errors), and handling asynchronous data fetching with TaskEither. It promotes a highly functional, predictable coding style for React 18/19 and Next.js.

A comprehensive guide for implementing reliable and resilient network communication in modern applications. Covers best practices for API requests, utilizing libraries like React Query/SWR for advanced data fetching, implementing robust error handling with retries and exponential backoff, managing authentication tokens, and ensuring offline-first support across various environments (including Expo Router loaders).
