Can I rename files while renaming classes?

Yes, the rename command includes a --rename-file option to keep your file system in sync with your type names automatically.

Is it safe to use for large-scale refactoring?

Absolutely. It includes a mandatory preview mode and semantic checking to ensure changes are consistent across the entire solution before application.

How does this differ from standard text search?

This skill uses Roslyn APIs to understand C# semantics, ensuring it identifies actual symbol usages rather than just matching text in comments or strings.

Does it work with existing .sln and .csproj files?

Yes, it automatically discovers .sln or .csproj files in your directory to build a semantic model of your solution.

Developer Tools

Provides compiler-accurate semantic analysis for C# projects using Roslyn APIs for precise refactoring and code navigation.

C# Project Expert is a specialized skill that empowers Claude with deep, compiler-level understanding of .NET solutions. By utilizing Roslyn-powered semantic analysis rather than simple text search, it allows for high-confidence refactoring, including safe solution-wide renames, unused code detection, and detailed inheritance mapping. It is the ideal tool for developers managing complex C# codebases who need to accurately trace method call chains, find interface implementations, and resolve compilation diagnostics across multiple projects.
