What is JIT inlining analysis?

It allows you to see which methods the Just-In-Time compiler has merged into callers, helping you verify that your 'hot paths' are properly optimized.

Does this skill require a graphical user interface?

No, the Profile skill is designed specifically for CLI environments and outputs structured text that is easily interpreted by both developers and AI.

Can I use this to analyze logs from a production environment?

Yes, you can use the --input flag to analyze existing .nettrace or .gcdump files captured from any environment.

Which versions of .NET are supported?

This tool requires the .NET 10 SDK or newer to take advantage of dnx support and modern profiling capabilities.

分析と監視

Profiles .NET applications for CPU, memory, contention, and JIT performance directly from the command line.

The Profile skill integrates the Asynkron Profiler into Claude, providing a powerful suite of diagnostics for .NET 10+ applications. It enables developers to identify performance bottlenecks, memory leaks, and thread contention by generating structured, AI-readable text reports including call trees and hot function tables. By wrapping standard tools like dotnet-trace and dotnet-gcdump, it facilitates an iterative optimization workflow without the need for a complex GUI.
