Skill UI

A comprehensive guide for developing custom editor components, theming, and CMS integration for the Website Builder using Next.js. Developers learn to register components, define configurable inputs (text, color, image, lexical), handle complex props, and understand the unique Admin iframe architecture.

This skill enforces output quality and evidence verification across security audits like SAST, SCA, and code reviews. It prevents suppression of valid findings and ensures reports meet quality thresholds before delivery. Includes components for self-critique, anti-rationalization, and continuous learning to maintain intellectual honesty and accuracy in security analysis workflows.

Validates feature-level integration after all tasks are implemented. Checks cross-task consistency, full test suite execution, requirements coverage, design alignment, and boundary violations. Ensures data flows between components, interfaces match, and no orphaned code or conflicting implementations exist. Provides GO/NO-GO assessment for feature completion.

Generates a high-conversion, single-column HTML email optimized for product launches, newsletters, and brand announcements. This skill structures the email with key components including a masthead, hero image block, dynamic headline lockup, specifications grid, and a single primary CTA, ensuring a professional and cohesive marketing message.

This skill pulls the latest GEO-SEO components, including skills, agents, scripts, and schema templates, from the official upstream repository. It performs a detailed comparison (diff) to show all changes—new, modified, or removed—before applying the update. It ensures local customizations are preserved while keeping the toolkit current. Use this whenever you suspect your local setup might be outdated.

This skill generates a complete, standalone, and highly structured pricing page in standalone HTML. It automatically respects the active design system (colors, typography, components) and supports defining 2-4 plan tiers, including feature cards, comprehensive comparison tables, and an FAQ section. Ideal for product marketing and sales-focused websites.

HTTP Parameter Pollution (HPP) occurs when a single request contains multiple instances of the same parameter key. Different components in the request path (e.g., WAFs, proxies, application frameworks) may parse these duplicate keys using different rules (first value, last value, array join). This skill teaches how to exploit these discrepancies to bypass security checks, execute SSRF, or manipulate business logic.

This catalog provides essential database abstractions and specialized clients for robust data persistence. It includes core components like DbRegistry, DynamoDBClient, and various filtering utilities. By utilizing these standardized imports, developers can standardize data access logic, ensuring clean code separation, type safety, and scalable architecture in their applications.

The CommunityToolkit.Mvvm Messenger provides a robust Publish/Subscribe messaging system for ViewModels and other objects. It allows multiple components to communicate asynchronously without holding direct references, effectively eliminating tight coupling. Supports various messaging patterns, including simple value broadcasts, request/reply (sync/async), and collection requests, making it ideal for complex applications using WPF, WinUI 3, .NET MAUI, or Avalonia.

This tool automatically converts design screenshots or visual exports into structured, functional Vue 3 Composition API components. It supports popular UI libraries like Vant, Element Plus, and Ant Design Vue. By batch converting screenshots, it streamlines the development process from raw design assets to reusable, production-ready code, significantly boosting frontend development efficiency.

This guide helps users navigate and understand the complex components of the ECC (Everything Claude Code) ecosystem, including skills, commands, agents, hooks, and rules. It provides structured paths for new user onboarding, feature discovery, installation planning, and troubleshooting, ensuring answers are derived from the current repository state.

This guide provides expert CRO strategies for optimizing in-app monetization moments, such as paywalls, upgrade modals, and upsell prompts. It covers the entire user journey from freemium conversion and usage limit management to trial expiration. Learn core principles like 'Value Before Ask' and how to design friction-free, high-converting components to maximize paid adoption.
