Guide for running MSBuild unit tests efficiently. Use when running, scoping, filtering, or speeding up unit tests in this repository, or when finalizing a change with a heavier validation pass. Covers xUnit v3 + Microsoft.Testing.Platform (MTP) specifics and which `dotnet test` flags do and don't apply.
Regenerate Static Web Assets test baselines. USE FOR: fixing "generated manifest should match the expected baseline" errors, updating baseline JSON files after legitimate build output changes, understanding the baseline comparison system.
Understand and fix Static Web Assets Pack tests. USE FOR: fixing Pack test assertion failures after nupkg content changes, tracing MSBuild conditions to expected nupkg content, updating test assertions for new or changed package layouts, understanding conditional pack logic in .targets files.
Parse and analyze Visual Studio TRX test result files. Use when asked about slow tests, test durations, test frequency, flaky tests, failure analysis, or test execution patterns from TRX files.
Guide for testing bug reproductions against locally-built MSBuild. Use this when you have a repro project and want to verify a fix works before submitting a PR.
Use this skill when you are implementing a change on src\StaticWebAssetsSdk and want to test the behavior locally to validate it works as expected.
Fix F# debugging issues (breakpoints, .pdb, sequence points). Build, run VS integration tests, inspect IL/PDB.
Build, test, and validate changes in the vstest repository. Use when building vstest projects, running unit tests, smoke tests, or acceptance tests, or when deploying locally built vstest.console for manual testing.
Performs multi-agent, multi-model code review of F# compiler PRs across 19 dimensions including type checking, IL emission, binary compatibility, and IDE performance. Dispatches parallel assessment agents per dimension, consolidates with cross-model agreement scoring, and filters false positives. Invoke when reviewing compiler changes, requesting expert feedback, or performing pre-merge quality checks.
Reviews MSBuild code changes using a 24-dimension methodology. Activates for code review, PR review, pull request analysis, design review, architecture review, code quality assessment, or style check of MSBuild code. Covers backwards compatibility, ChangeWave discipline, performance, allocation awareness, test coverage, error message quality, logging, string comparison, API surface, target authoring, cross-platform correctness, code simplification, concurrency, naming, SDK integration, evaluation model integrity, correctness, dependency management, security, and build infrastructure.
