Skill UI

Provides comprehensive guidelines for modern web development, covering critical areas like security best practices (e.g., CSP, HTTPS enforcement, input sanitization), browser compatibility (viewport, encoding), and avoiding deprecated APIs. Use this skill when aiming to audit, modernize, or improve the overall quality and robustness of web code.

This skill guides the development of robust, security-focused full-stack web applications. It ensures layered security coverage across the entire application stack, from database queries (parameterized queries) to API endpoints (authentication/authorization) and frontend components (input validation, output encoding). Use this when building end-to-end features, microservices, or REST APIs that require simultaneous attention to Frontend, Backend, and Security best practices.

Comprehensive checklist for application security hardening, covering input validation, output encoding, SQL/CSRF defenses, security headers, JWT best practices, secrets handling, rate limiting, and dependency audits to keep web services resilient.

A detailed guide for conducting authorized penetration tests to detect and exploit HTTP request smuggling flaws. This technique targets discrepancies in Content-Length and Transfer-Encoding parsing between front-end proxies (like CDNs or load balancers) and back-end servers, allowing attackers to bypass security controls and hijack subsequent requests.

A detailed methodology for identifying Cross-Site Scripting (XSS) vulnerabilities across web applications. It guides systematic testing for Reflected, Stored, and DOM-based XSS, covering payload bypass, output encoding evaluation, and assessing Content Security Policy (CSP) protection. Essential for OWASP WSTG testing and client-side security audits.

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.

Transforms existing code files into highly effective learning resources by adding context-aware educational comments. Acting as an expert educator, this tool tailors explanations—from foundational concepts for beginners to deep architectural insights for advanced practitioners—while strictly maintaining the original file's structure, encoding, and syntax. Ideal for generating self-documenting, pedagogically rich codebases.

This comprehensive checklist guides users through identifying and exploiting open redirect vulnerabilities in web applications. It covers parameter identification, advanced bypass techniques (e.g., URL encoding, CRLF injection), and chaining the vulnerability with other flaws like OAuth or SSRF. Ideal for web application penetration testing and bug bounty hunting.

This comprehensive checklist details advanced methods for bypassing Web Application Firewalls (WAFs) during security assessments. Techniques covered include encoding bypass (URL, Unicode, double encoding), HTTP header manipulation, IP rotation, payload obfuscation, and fingerprinting specific WAF vendors (e.g., Cloudflare, Akamai). It is essential for penetration testers evaluating the robustness of web defenses.

A comprehensive playbook for bypassing 401/403 Forbidden errors. Covers advanced techniques like path normalization tricks (encoding, traversal), HTTP method tampering, IP spoofing headers, and protocol downgrade attacks. Essential knowledge for penetration testing and security auditing.

A deep-dive playbook covering expert techniques for Path Traversal and Local File Inclusion (LFI). It details multiple bypass methods (encoding, null bytes, wrappers), target file enumeration on Linux and Windows, and advanced Remote Code Execution (RCE) escalation paths, such as log poisoning via PHP wrappers.

This utility uses ffmpeg's libass filter to permanently burn an SRT subtitle file into an MP4 video stream. It handles video re-encoding (H.264) while copying the audio track directly, ensuring high quality. Supports customization of font name, size, margin, and video encoding parameters (CRF, preset), making it essential for the final subtitling step in video content pipelines.
