Skill UI

A full-featured tool for comprehensive SEO site auditing. It supports full-site crawling, mapping site structure (URL discovery), and deep scraping of JavaScript-rendered content. Ideal for technical SEO audits, content inventory, and identifying link gaps.

This skill automatically generates comprehensive unit tests based on provided source code. It supports multiple programming languages (Python, JavaScript, Java, Go, Rust) and popular testing frameworks (pytest, Jest, JUnit). Use it to improve code coverage, test boundary conditions, and validate error handling efficiently, saving manual testing time.

This skill provides a comprehensive solution for embedding the powerful, Photoshop-compatible Photopea editor into any web application. Using photopea.js, developers can control the embedded instance via JavaScript, enabling advanced workflows such as opening remote files, loading local assets (fonts, brushes), executing custom scripts to manipulate layers and text, and exporting the final result in various formats (PNG, JPG, PSD, WebP). Ideal for building professional creative tools directly into your product.

A powerful tool for designing and writing deterministic, multi-agent workflow scripts in JavaScript. It allows users to orchestrate complex, repeatable, multi-step tasks using advanced patterns like fan-out, pipelines, loops, and judge-panels. Ideal for automating sophisticated business processes that require multiple specialized sub-agents and robust context management.

An internal utility designed for deep investigation of JavaScript or TypeScript stack traces. It analyzes complex runtime errors, providing specific checks for asynchronous boundaries, module resolution issues, JSON parsing failures, and type contract violations. It aids developers by generating minimal reproduction commands and identifying potential patch targets for robust error handling.

A comprehensive guide detailing modern, idiomatic, and efficient patterns for TypeScript and JavaScript development. It covers essential best practices from array manipulation (map, reduce) and destructuring to advanced asynchronous handling (async/await, Promise.all) and type safety best practices, helping developers write cleaner, more robust, and performant code.
