Skill UI

This skill enables user interaction within Three.js scenes, covering raycasting, camera controls, and input handling. It is essential for implementing click detection, touch support, and object selection in 3D web applications. Use it to transform passive renders into interactive experiences.

This skill automates the creation of comprehensive unit tests across multiple programming languages like Python, JavaScript, and Java. It analyzes source code to identify functions and classes, then generates maintainable test suites with strong coverage, edge case handling, and proper mocking. Ideal for developers seeking consistent test structures and improved code quality without manual writing.

uv is an extremely fast Python package installer and resolver written in Rust. This guide provides a comprehensive workflow for modern Python project management and dependency handling. Use this skill to set up new projects quickly, manage dependencies much faster than traditional tools like pip, resolve complex conflicts, and optimize CI/CD pipelines, especially when dealing with monorepos or needing reproducible builds.

This skill generates appropriate user feedback states for components and pages, including loading skeletons, empty states, error messages, and success toasts. It ensures consistent UI presentation by implementing specific design patterns for data-dependent areas, handling partial or full failures, and providing retry mechanisms. It follows design language references for animations and accessibility, suitable for React-based frontend development workflows.

Guides GitHub Copilot through V language development: installing the toolchain, structuring v.mod projects, building, formatting, vetting, testing, and writing idiomatic V with Option/Result error handling and immutability rules.

Build real-time conversational AI voice engines using async worker pipelines, streaming transcription, LLM agents, and TTS synthesis with interrupt handling and multi-provider support. Ideal for creating voice assistants, customer service agents, and voice-enabled applications that process streaming audio and integrate multiple AI providers effectively.

Master advanced vulnerability analysis principles aligned with OWASP 2025 standards. Learn to think like an attacker and defend like an expert. Covers supply chain security, attack surface mapping, risk prioritization using CVSS and EPSS, and exceptional condition handling. Includes methodologies for scanning, code pattern analysis, and cloud security considerations to identify and mitigate critical security risks effectively.

Manage ownership, retention, and cleanup of downloaded weather data across one-shot jobs, interactive viewers, caches, failures, and cancellation. This skill ensures temporary files are removed after use, interactive data persists until closed, and shared caches are protected. It covers Python implementation for safe file handling, atomic moves, and idempotent cleanup logic to prevent data leaks or corruption during processing.

This skill covers web browser game development, including framework selection (Phaser, Three.js, Babylon.js), hybrid DOM+canvas architectures, WebGPU adoption, performance optimization, PWA implementation, and audio handling. Use it for building HTML5/WebGL games or selecting browser runtimes.

This skill performs intelligent multi-strategy web scraping to extract structured data from web pages, including tables, lists, and prices. It supports pagination handling, monitoring, and exporting data to CSV or JSON formats. Designed for safe data extraction without executing untrusted content.

A comprehensive guide detailing best practices for executing commands on Windows using PowerShell and CMD. It addresses critical pitfalls such as handling spaces in file paths, ensuring correct character encoding (UTF-8), using native cmdlets, and managing long path limits. Essential for developers building robust, cross-platform Windows automation scripts.

A critical skill for reviewing WooCommerce extensions, payment integrations, and checkout logic before deployment. Ensures code follows security standards, HPOS compatibility, proper data handling, and runtime discipline to prevent systematic AI failures.
