What is the difference between this skill and dotnet-tooling?

This skill is for troubleshooting broken applications (crashes, hangs, leaks), while dotnet-tooling is focused on performance profiling, optimization, and code decompilation.

Does this skill work for .NET applications running on Linux?

Yes, it fully supports Linux and macOS environments using tools like dotnet-dump, lldb with SOS extensions, and createdump for containerized applications.

Can Claude analyze Windows crash dumps (.dmp) with this skill?

Absolutely. It integrates with WinDbg MCP to analyze crash dumps, perform !analyze -v commands, and inspect the stack for both managed and native code.

Can I use this for debugging deadlocks in production?

Yes, the skill includes specific workflows for hang and deadlock triage, utilizing !syncblk, !dlk, and thread wait chain analysis to identify locking issues.

分析と監視

Diagnoses complex .NET and native application crashes, hangs, memory leaks, and high CPU usage across Windows, Linux, and macOS.

This skill equips Claude with specialized expertise for deep-dive diagnostics of .NET, native, and mixed-mode applications. By leveraging powerful tools such as WinDbg, dotnet-dump, and lldb with SOS, it provides a structured framework for analyzing crash dumps, investigating deadlocks, and triaging memory pressure. It is specifically designed for production-grade troubleshooting, offering guidance on symbol configuration, container-based diagnostics in Docker or Kubernetes, and generating detailed evidence-based reports to pinpoint root causes in C# and CLR environments.
