An expert playbook for systematically testing Insecure Direct Object References (IDOR) and Broken Object/Function Level Authorization (BOLA/BFLA). This guide covers finding object identifiers across all request vectors (URL, body, headers, cookies), implementing A-B testing methodologies, identifying various ID patterns, and executing horizontal or vertical privilege escalation attacks. Essential for deep API security auditing.

A comprehensive playbook covering advanced smart contract audit techniques for Solidity/EVM. Focuses on critical patterns like reentrancy (cross-contract), integer overflows, access control misuse, delegatecall exploits, flash loans, and advanced MEV/front-running attacks. Essential for securing DeFi protocols.

This playbook provides advanced techniques for symbolic execution using angr, Z3, and Unicorn Engine. It covers automating CTF challenges, handling constraint solving patterns, function hooking, memory manipulation, and emulating custom virtual machines for binary analysis and key recovery.

This catalog provides 11 core abstractions for implementing robust mailing functionalities within the Webiny API architecture. It includes Use Cases, Repositories, and various Event Handlers (e.g., before/after send, save). Developers should use these structured patterns to ensure their mailer logic is modular, highly testable, and follows industry best practices.

A comprehensive guide and pattern library for reviewing, troubleshooting, and safely modifying Cisco IOS and IOS-XE configurations. This skill outlines best practices for using read-only 'show' commands, validating ACL wildcard masks, managing configuration hierarchy, and following stringent change control procedures to prevent network disruptions.

This guide outlines architectural patterns and best practices for building scalable, production-ready APIs with FastAPI. It covers proper project structure, separating concerns using routers, services, and CRUD layers, implementing dependency injection for database sessions and authentication, defining Pydantic schemas for request/response, handling asynchronous operations, and managing custom error responses.

The CommunityToolkit.Mvvm Messenger provides a robust Publish/Subscribe messaging system for ViewModels and other objects. It allows multiple components to communicate asynchronously without holding direct references, effectively eliminating tight coupling. Supports various messaging patterns, including simple value broadcasts, request/reply (sync/async), and collection requests, making it ideal for complex applications using WPF, WinUI 3, .NET MAUI, or Avalonia.

A comprehensive guide to Redis best practices for backend development. Learn how to implement critical features such as Cache-Aside, Write-Through caching, rate limiting, distributed locks, and reliable messaging using Pub/Sub and Redis Streams. Essential for building scalable, high-performance production systems.

This guide details the architectural and implementation patterns for building modular applications or microservices using the tinystruct Java framework. It covers core concepts like using the @Action annotation for dual routing (CLI/HTTP), managing request state with Context, and using native Builder for JSON serialization, ensuring a lightweight and structured development environment.

A comprehensive guide covering best practices for the Vite build tool. Learn how to configure advanced features such as environment variables, plugins, HMR, dependency pre-bundling, and optimizing the final production build for modern web applications.

This comprehensive skill facilitates deep integration with X (Twitter) data, supporting advanced scraping, user lookup, and data extraction. It provides multiple integration patterns for developers: dedicated SDKs (Python, TypeScript, Go, etc.), REST endpoints, hosted Apify Actors, and agent automation via MCP. Ideal for building robust data pipelines, monitoring systems, and AI-powered applications requiring real-time X data.

The Ejentum Reasoning Harness is a comprehensive library of cognitive operations designed to guide complex AI agents through critical thinking tasks. It exposes four specialized harnesses (reasoning, code, anti-deception, memory) that mitigate common failure modes like hallucination and reasoning decay. Instead of a fixed answer, the agent ingests a detailed, executable scaffold—including failure patterns, procedures, and falsification tests—to ensure robust, self-verified output.
