A comprehensive deep dive into reverse engineering ransomware encryption mechanisms. It details the analysis of hybrid encryption models (AES/RSA), identifying specific cryptographic APIs (CryptoAPI, CNG), and locating implementation flaws such as weak key generation or IV reuse. This guides authorized security professionals in finding potential decryption opportunities without paying a ransom.

A comprehensive guide to writing robust and maintainable tests in Rust. It covers various advanced testing patterns, including Unit, Integration, Async, and Property-Based testing. Learn how to apply the TDD (Test-Driven Development) cycle (RED-GREEN-REFACTOR) to enhance code reliability and ensure high code coverage.

This skill reviews code differences (diffs) to identify opportunities for improvement in clarity, reusability, efficiency, and overall quality. It employs multiple specialized sub-agents (e.g., Code Reuse, Efficiency, Quality) to audit changes. It can provide high-confidence, behavior-preserving fixes when requested, ensuring the code adheres to best practices without introducing regressions. Best used when refactoring, cleaning up, or auditing a specific code scope.

This guide provides comprehensive testing patterns for C# and .NET applications. It covers best practices using xUnit, FluentAssertions, and advanced techniques like mocking (NSubstitute/Moq), parameterized testing, and full integration testing using Testcontainers and WebApplicationFactory. Ideal for improving test quality, coverage, and developing robust, maintainable codebases.

A comprehensive guide for setting up production-grade CI/CD pipelines for Go projects using GitHub Actions. This skill covers essential quality gates including unit testing, linting (golangci-lint), static analysis security testing (SAST), vulnerability scanning, dependency management, Docker builds, and automated releases using GoReleaser.

A comprehensive guide to the Go programming language ecosystem. This resource curates official documentation, essential newsletters, key developer profiles, and community hubs. Use this guide when you need to stay current with Go language features, discover new libraries, or keep up with industry best practices and community discussions.

A comprehensive guide to using testify/stretchr in Go for writing robust, reliable, and self-explanatory unit tests. It deeply covers core concepts like assertions (Equal, Contains, etc.), setup/teardown using test suites, mocking dependencies, and the critical difference between `assert` (non-stopping) and `require` (stopping on failure). Ideal for any Go developer seeking to improve test coverage and quality.

This skill provides a comprehensive guide to using the Mockito package for advanced unit testing in Dart and Flutter. Learn how to correctly distinguish between real objects, fakes, and mocks. Master techniques for stubbing methods, verifying interactions, capturing arguments, and ensuring test isolation, leading to more reliable and maintainable tests.

Master the art of unit testing in Dart and Flutter using the Mocktail package. This guide details best practices for mocking dependencies, differentiating between mocks, fakes, and real objects, stubbing methods, verifying interactions, and handling complex argument matchers. Learn how to write robust, reliable, and maintainable tests that isolate the component under test.

Comprehensive Go testing guidance that spans table-driven subtests, testify suites, mocking, unit/integration tests, benchmarks, coverage, fuzzing, goleak leak detection, snapshot checks, and GitHub Actions CI to keep production suites reliable.

This guide provides a comprehensive, step-by-step process to scaffold a modern Spring Boot application using Kotlin. It covers downloading the template, configuring dependencies (including SpringDoc and ArchUnit), and setting up complex polyglot environments using Docker Compose. Supports PostgreSQL, MongoDB, Redis, and WebFlux reactive programming.

This guide provides comprehensive best practices for writing robust and effective unit tests using JUnit 5 in Java. It covers standard test structures (Arrange-Act-Assert), advanced data-driven testing using parameterized methods, best assertion practices (including AssertJ), and dependency isolation using mocking frameworks like Mockito. Ideal for developers aiming to improve code coverage and test reliability.
