A comprehensive guide for developers migrating between different versions of the Flexport API, specifically detailing changes from v1 to v2. It covers breaking changes in request headers, response parsing (e.g., _object to data), pagination formats, and error structures, ensuring smooth integration updates.

Provides a comprehensive production checklist specifically for WebContainer applications built using the StackBlitz SDK. This guide helps developers ensure that their web applications are robust and ready for deployment by checking essential aspects like security headers, cross-browser compatibility, and necessary fallback mechanisms.

A comprehensive guide and workflow for deploying static websites (e.g., Vue, React, Angular, Hugo, Jekyll) from a local environment to a production server using VSCode SFTP. This skill covers setting up secure SFTP connections, generating production-ready Nginx configurations (including security headers, caching, and HTTPS redirects), and providing a complete deployment checklist for smooth CI/CD-like workflows.

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 detailed playbook covering CRLF (Carriage Return Line Feed) injection techniques. This exploit targets insecure handling of user input within HTTP response headers (e.g., Location, Set-Cookie) or log files. It demonstrates advanced attacks like response splitting, XSS escalation via double CRLF, cache poisoning, and session fixation, essential for deep security testing.

This skill validates the correctness and completeness of any API request. It rigorously checks the HTTP method, URL structure, required headers, body format, authentication details, and query parameters. Use it to debug cURL commands, verify endpoint calls, or ensure API structures adhere to best practices, providing immediate, actionable feedback on required fixes.
