How does it improve application security?

It identifies and remediates instances where raw exception details or stack traces might be exposed to users, ensuring your API follows OWASP security standards.

Which versions of .NET does this skill support?

The skill is optimized for .NET 6 and newer for features like IExceptionHandler, while the Result pattern and general fixes support C# 7.0 and above.

Can it detect issues in asynchronous code?

Yes, it specifically scans for common async pitfalls, including unawaited tasks and 'fire-and-forget' methods that lose exception context.

Will this skill automatically change my code?

By default, the skill runs in investigation-only mode. It will only apply fixes if you explicitly use the --fix-all flag.

Security & Testing

Analyzes and remediates common .NET exception handling anti-patterns to improve application reliability and security.

The .NET Exception Handling Optimizer is a specialized skill designed to systematically audit and refactor C# codebases. It automatically detects .NET projects and deploys specialized agents to identify the top 10 most common error-handling mistakes, such as broad catches, swallowed exceptions, and 'throw ex' anti-patterns. Beyond simple detection, it orchestrates complex refactoring workflows, implementing production-ready patterns like GlobalExceptionHandler and Result<T> to ensure your application is secure, performant, and compliant with Microsoft's best practices.
