About this skill

What it does. Inspects the project to identify MSTest versions, target frameworks, package configuration and affected APIs, then updates packages and source for v4. It handles custom test attributes, assertions, expected exceptions, lifecycle changes, and runner or discovery settings, and verifies builds and tests.

When to use it. Use for a v3-to-v4 upgrade, post-upgrade compiler or runtime failures, or MSTest.Sdk discovery and CI issues. Do not use for v1/v2 migrations, framework conversion, runner-only migrations, or non-MSTest projects.
