Performs safe, behavior-preserving refactoring of C#/.NET code, verified with build, tests, and analyzers.

What this skill does for you

Performs safe, behavior-preserving refactoring of C#/.NET code, verified with build, tests, and analyzers. USE FOR: rename or move a symbol/type/file; extract a method/type/interface; inline a wrapper/method/local; merge or consolidate near-identical classes or duplicate helpers; split or modernize C# code; generated/partial declarations; public, serialized, friend-assembly, or multi-targeted contracts; and mixed requests where a feature, bug fix, package/framework upgrade, public nullability change, or other behavior/contract change is presented as a refactor and must be separated or declined. DO NOT USE FOR: ordinary feature or bug-fix requests not framed as refactoring; upgrades after reclassification (use dotnet-upgrade); new tests; or formatting-only passes (use dotnet format).
