Skill UI

A comprehensive guide covering 33+ essential JavaScript concepts, from fundamental types and type coercion to advanced topics like closures, event loop mechanics, hoisting, and asynchronous programming (Promises). Ideal for developers who need to deepen their understanding of JavaScript's internal workings, debug complex behavior, or teach robust JS fundamentals.

Comprehensive guide to Go's built-in and standard library data structures, including slices, maps, and arrays. Deep dives into memory allocation, capacity growth mechanics, and best practices for optimization. Learn when to use `strings.Builder`, preallocation techniques, `container/heap`, and managing pointers safely with `unsafe.Pointer` and `weak.Pointer`. Ideal for optimizing performance-critical Go code.

Expert assistance for building, modifying, and debugging Minecraft server plugins for the Paper, Spigot, and Bukkit ecosystems. This includes implementing complex gameplay mechanics such as minigames, advanced combat systems, persistent player progression (perks, economy, quests), custom command handling, and robust state management. We handle configuration, listener registration, and adherence to best practices for Java-based server API usage.

Generate a high-fidelity, multi-screen mobile prototype simulating a gamified experience, perfect for habit trackers, life management apps, or RPG concepts. The output features three distinct phone frames: cover/value proposition, daily quests dashboard, and detailed quest view, all presented on a single dark showcase stage. Ideal for visualizing user journeys and engagement mechanics.

A comprehensive playbook detailing advanced exploitation techniques in decentralized finance (DeFi). Covers flash loan mechanics, price oracle manipulation (spot vs. TWAP), MEV extraction strategies (Sandwich, JIT), governance exploits, and core smart contract vulnerabilities. Essential for security auditors and risk analysts.

A comprehensive guide to exploiting PHP's loose type checking (using '==') and type juggling mechanics. This skill is crucial for bypassing security controls like authentication checks, HMAC/signature validations, and token comparisons that fail to use strictly typed comparisons (===) or timing-safe functions (hash_equals). Includes techniques for magic hash collisions and PHP version delta analysis.

An expert-level playbook covering non-obvious XSS techniques, advanced payload selection across various sinks (DOM, SVG, HTML attributes, JavaScript), and sophisticated defense bypass strategies. Use this guide for real-world penetration testing, including WAF bypass, CSP bypass, HttpOnly bypass, and XS-Leaks side channel exploitation. It assumes deep knowledge of web vulnerability mechanics.
