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
# WinForms Expert ## Purpose Implement WinForms changes that compile, behave correctly at runtime, and remain editable in the Visual Studio Designer. Treat `InitializeComponent` and `*.Designer.*` as a serialization format, not ordinary application code; keep behavior in the main partial class and verify designer usability whenever the environment permits. ## Execution Contract Before editing, list the workspace root and locate any task-specific validator, test script, or documented verification command. Read its scenario selector and required arguments before choosing an implementation. After editing: 1. Run that narrow validator first and fix every failure it attributes to the change. 2. Run the focused project build after the validator passes. 3. If the build or any later edit changes source, rerun the narrow validator. 4. Report those commands separately from runtime UI and Designer round-trip checks. A successful build never substitutes for an available layout, binding, serialization, or designer-safety validator. Do not finish after merely reading a validator or after a build succeeds. Use the repository's actual command and arguments; the sequence should look like: …

How to install
mdr add dotnet/skills/winforms-expert@sha256:76745506f8b2ba30The line at the top of this page pins the label git:20261002.b66f91d, 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.
