1. Software Development

Provides a comprehensive guide for implementing the Test Data Builder Pattern in .NET to create maintainable and readable test data using fluent interfaces and semantic methods.

Provides comprehensive guidance for creating test doubles (mocks, stubs, spies) using NSubstitute in .NET unit testing to isolate dependencies and verify method interactions.

Guides advanced AutoFixture customization for .NET unit testing, including DataAnnotations integration and ISpecimenBuilder implementation.

Enables containerized database testing for .NET applications using Testcontainers with SQL Server, PostgreSQL, and MySQL, supporting EF Core and Dapper.

Provides advanced .NET testing guidance for integration, API, containerized, and microservices testing scenarios with framework migration support.

Advanced TUnit guide for .NET testing: data-driven tests, dependency injection, integration with WebApplicationFactory and Testcontainers.

Provides a comprehensive guide to TUnit, a next-generation .NET testing framework, covering test discovery, AOT compilation, and asynchronous assertions with xUnit syntax comparison.

Comprehensive guide for advanced ASP.NET Core Web API integration testing using WebApplicationFactory, ProblemDetails validation, and Testcontainers orchestration.

Facilitates creation, editing, and verification of Claude skills before deployment.

Guides .NET testing of private/internal members with InternalsVisibleTo, reflection, and refactoring patterns including Strategy and AbstractLogger.

Exits read-only mode to activate Builder Mode, enabling direct development and editing capabilities.

Activates project-wide read-only mode to prevent accidental modifications, ensuring safety during critical development phases.

Enables safe code refactoring through incremental changes, automated testing, and diagnostic checks to maintain code integrity.

Generates and validates unit, integration, and end-to-end tests for Node.js and TypeScript applications.

Provides a checklist for reviewing pull requests to ensure adherence to clean code practices, SOLID principles, and code safety.

Command handler for executing Claude Code commands within the telegram_agent project to fix bugs and add features.

Provides efficient access to function source code, callers, and callees, eliminating manual codebase inspection.

Enables developers to discover files and code locations related to specific concepts or features in an unfamiliar codebase.

Enforces Architecture Decision Records (ADR) compliance to guide design choices, manage technical debt, and prevent resume-driven development in software projects.

Automates code quality assessments including refactoring, performance optimization, and security audits to reduce technical debt.

Enables parallel development by creating isolated working trees for multiple Git branches without context switching.

Verifies software implementation against specifications, acceptance criteria, and design documents to ensure alignment with requirements.

Systematically identifies underlying causes of software bugs, errors, and unexpected behavior through debugging and stack trace analysis.

Automates evaluation of code quality, AI output testing, and implementation correctness through defined acceptance criteria.
