Safely refactors C#/.NET code without changing behavior. USE FOR any request to refactor, rename, move, extract, inline, merge, consolidate, deduplicate, split, or modernize C# code, including partial/generated declarations, wrappers, public APIs, serialization/reflection/configuration names, friend assemblies, conditional compilation, and multi-targeted projects. Also use when a request calls a feature, bug fix, package/framework upgrade, or public nullability change a refactor and the…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# C# Refactoring (behavior-preserving) A refactor changes **structure**, never observable **behavior**. Do the edit with binding-aware tools, then confirm behavior held with a build + the relevant tests. Keep the effort proportional to the change: a one-line local rename does not need the ceremony a public multi-targeted change does. ## Mandatory gate: classify before validation or editing Read only enough repository context to classify **each requested operation**. Do this before restoring, building, or making an edit. Classification precedence is: - If the request explicitly asks for at least one separable behavior-preserving operation, complete that structural work and defer only the behavior-changing or contract-changing operations. Do not invent or infer structural work to avoid the stop response. - If the structural and behavior-changing parts cannot be separated, use the whole-request stop response and state why they are inseparable. - Otherwise, use the whole-request stop response only when **every** requested operation is outside behavior-preserving refactoring. For a whole request that is outside behavior-preserving refactoring: …

How to install
mdr add dotnet/skills/csharp-refactoring@sha256:a5516d690bc07136The line at the top of this page pins the label git:20260917.909a8cb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
