Skill UI

This skill details the architecture and implementation of a robust API Gateway, serving as the single entry point for multiple backend microservices. It centrally manages critical cross-cutting concerns, including path-based and header-based routing, JWT/OAuth2 authentication, rate limiting, load balancing, and circuit breaker protection. This pattern is essential for building resilient, scalable, and maintainable microservices architectures, significantly simplifying client integration and request management.

A comprehensive guide to building production-grade Laravel applications. It details architectural patterns for achieving scalability and maintainability, covering service/action separation, advanced Eloquent usage (casts, scopes), dependency injection via service containers, and robust API routing patterns.

This skill guides comprehensive security testing for Host Header Injection vulnerabilities in web applications. It simulates attacks to identify critical risks such as password reset poisoning, web cache poisoning, Server-Side Request Forgery (SSRF), and virtual host routing manipulation. It is essential for penetration testers assessing backend security behind proxies and load balancers.

A comprehensive collection of composable handlers and middlewares for Go's standard slog package. This skill enables developers to build robust, multi-stage logging pipelines by implementing critical steps like log sampling (throughput control), attribute formatting (PII stripping), advanced routing, and sinking logs to various professional backends (e.g., Sentry, Loki, Datadog). Ideal for production-grade services requiring high observability.

This comprehensive guide details the implementation of secure, event-driven webhooks for Adobe I/O Events. It covers the complete lifecycle, including programmatic webhook registration, handling the challenge-response handshake, implementing robust RSA-SHA256 signature verification, and routing incoming events from services like Creative Cloud and Experience Platform. Essential for building mission-critical, integrated backend systems within the Adobe ecosystem.

This guide demonstrates how to implement a robust webhook handler for the Podium platform. Developers can process real-time business events—including incoming customer messages, new reviews, and completed payments—by setting up event routing and ensuring idempotent processing. Essential for integrating critical communication and transaction data into a backend system.

This module provides a comprehensive catalog of abstractions and utilities for handling API webhooks within the Webiny framework. It covers essential components such as payload types (IWebhookPayload), domain models (Webhook), delivery mechanisms, and core services like WebhookDispatcher and WebhookFactory. It supports advanced features including event routing, data validation, and secure payload signing, making it ideal for backend integration development.

This specialized skill is used to trace complex network requests through multi-layered infrastructure, such as reverse proxies, container boundaries, and various header manipulations. It is essential for determining which specific node, proxy rule, or derived header ultimately serves a live request within a sandboxed environment. Use it when analyzing VHost routing, path rewrites, or X-Forwarded headers to pinpoint the decisive backend.

A specialized, downstream skill designed for forensic analysis within a confined sandbox environment, particularly for CTF challenges. It guides the user to inspect the full stack behavior, including API interactions, server routing, browser state (cookies, local storage), and asynchronous worker processes. Use this skill to trace complex, end-to-end request flows, debug authentication/session leaks, or diagnose discrepancies between frontend UI and backend enforcement.
