.NET Crash Dump Collection

This skill configures and collects crash dumps for modern .NET applications (CoreCLR and NativeAOT) on Linux, macOS, and Windows — including containers.

Stop Signals

🚨 Read before starting any workflow.

• Stop after dumps are enabled or collected. Do not open, analyze, or triage dump files.
• If the user already has a dump file, this skill does not cover analysis. Let them know analysis is out of scope.
• Do not install analysis tools (dotnet-dump analyze, windbg). Only install collection tools (dotnet-dump collect). Using lldb for on-demand dump capture on macOS is allowed — it ships with Xcode command-line tools and is not being used for analysis.
• Do not trace root cause of crashes. Report the dump file location and move on.
• Do not modify application code. Configuration is environment-only (env vars, OS settings, container specs).
