### dotnet-msbuild

- [Analyzing MSBuild Failures with Binary Logs](.agents/skills/binlog-failure-analysis/SKILL.md) — _skill_ — This skill diagnoses MSBuild build failures from a `.binlog` file. The preferred path uses the **binlog MCP server** (`Microsoft.AITools.BinlogMcp`, exposed under the `binlog` MCP namespace) which is bundled with this plugin. If the MCP server is not available, fall back to the **binlog replay** workflow at the bottom.
- [Build Performance Baseline & Optimization](.agents/skills/build-perf-baseline/SKILL.md) — _skill_ — Before optimizing a build, you need a **baseline**. Without measurements, optimization is guesswork. This skill covers how to establish baselines and apply systematic optimization techniques.
- [Custom Target Authoring Patterns](.agents/skills/target-authoring/SKILL.md) — _skill_ — Canonical patterns from `Microsoft.Common.CurrentVersion.targets` in the MSBuild repository.
- [Detecting OutputPath and IntermediateOutputPath Clashes](.agents/skills/check-bin-obj-clash/SKILL.md) — _skill_ — This skill helps identify when multiple MSBuild project evaluations share the same `OutputPath` or `IntermediateOutputPath`. This is a common source of build failures including:
- [Generate Binary Logs](.agents/skills/binlog-generation/SKILL.md) — _skill_ — **Pass the `/bl` switch when running any MSBuild-based command.** This is a non-negotiable requirement for all .NET builds.
- [Including Generated Files Into Your Build](.agents/skills/including-generated-files/SKILL.md) — _skill_ — Files generated during the build are generally ignored by the build process. This leads to confusing results such as: - Generated files not being included in the output directory - Generated source files not being compiled - Globs not capturing files created during the build
- [MSBuild Anti-Pattern Catalog](.agents/skills/msbuild-antipatterns/SKILL.md) — _skill_ — A numbered catalog of common MSBuild anti-patterns. Each entry follows the format:
- [MSBuild Extension Points](.agents/skills/extension-points/SKILL.md) — _skill_ — How the MSBuild pipeline provides hooks for SDKs, NuGet packages, repos, and users to inject custom logic.
- [MSBuild Item Management Patterns](.agents/skills/item-management/SKILL.md) — _skill_ — Canonical patterns for working with item groups, from `Microsoft.Common.CurrentVersion.targets`.
- [MSBuild Modernization: Legacy to SDK-style Migration](.agents/skills/msbuild-modernization/SKILL.md) — _skill_ — **Legacy indicators:**
- [MSBuild Property Patterns](.agents/skills/property-patterns/SKILL.md) — _skill_ — Canonical property definition and manipulation patterns from the MSBuild repository.
- [MSBuild Server for CLI Caching](.agents/skills/msbuild-server/SKILL.md) — _skill_ — Use the MSBuild Server to cache evaluation results across CLI builds, matching the performance advantage Visual Studio gets from its long-lived MSBuild process.
- [Misleading ResolveProjectReferences Time](.agents/skills/resolve-project-references/SKILL.md) — _skill_ — Prevent misguided optimization of `ResolveProjectReferences` by explaining that its reported time is wall-clock wait time, not CPU work.
- [Organizing Build Infrastructure with Directory.Build Files](.agents/skills/directory-build-organization/SKILL.md) — _skill_ — Understanding which file to use is critical. They differ in **when** they are imported during evaluation:
- [SKILL](.agents/skills/build-parallelism/SKILL.md) — _skill_ — - `/maxcpucount` (or `-m`): number of worker nodes (processes) - Default: 1 node (sequential!). Always use `-m` for parallel builds - Recommended: `-m` without a number = use all logical processors - Each node builds one project at a time - Projects are scheduled based on dependency graph
- [SKILL](.agents/skills/build-perf-diagnostics/SKILL.md) — _skill_ — 1. **Generate a binlog**: `dotnet build /bl:{} -m` 2. Use the **binlog MCP server** (`Microsoft.AITools.BinlogMcp`, exposed under the `binlog` MCP namespace) which is bundled with this plugin
- [SKILL](.agents/skills/eval-performance/SKILL.md) — _skill_ — For a comprehensive overview of MSBuild's evaluation and execution model, see [Build process overview](https://learn.microsoft.com/en-us/visualstudio/msbuild/build-process-overview).
- [SKILL](.agents/skills/incremental-build/SKILL.md) — _skill_ — MSBuild's incremental build mechanism allows targets to be skipped when their outputs are already up to date, dramatically reducing build times on subsequent runs.

### dotnet-test

- [.NET Test Framework Reference](.agents/skills/dotnet-test-frameworks/SKILL.md) — _skill_ — Language-specific detection patterns for .NET test frameworks (MSTest, xUnit, NUnit, TUnit).
- [Assertion Diversity Analysis](.agents/skills/assertion-quality/SKILL.md) — _skill_ — Analyze test code in any supported language to measure how varied and meaningful the assertions are. Produce a metrics report that reveals whether tests verify different facets of correctness — not just "output equals X" but also structure, exceptions, state transitions, side effects, and invariants.
- [CRAP Score Analysis](.agents/skills/crap-score/SKILL.md) — _skill_ — Calculate CRAP (Change Risk Anti-Patterns) scores for .NET methods to identify code that is both complex and undertested.
- [Code Testing Extensions](.agents/skills/code-testing-extensions/SKILL.md) — _skill_ — This skill provides access to language-specific guidance files used by the code-testing pipeline. Call this skill to get the file paths, then read the relevant file for your target language.

- [Coverage Analysis](.agents/skills/coverage-analysis/SKILL.md) — _skill_ — Raw coverage percentages answer "what code was executed?" — they don't answer what you actually need to know:
- [Detect Static Dependencies](.agents/skills/detect-static-dependencies/SKILL.md) — _skill_ — Scan a C# codebase for calls to hard-to-test static APIs and produce a ranked report showing which statics appear most frequently, which files are most affected, and which abstractions already exist in the .NET ecosystem to replace them.
- [Generate Testability Wrappers](.agents/skills/generate-testability-wrappers/SKILL.md) — _skill_ — Generate wrapper interfaces, default implementations, and DI service registration code for untestable static dependencies. For statics that already have .NET built-in abstractions (`TimeProvider`, `IHttpClientFactory`), guide adoption of the built-in. For statics without built-in alternatives, generate custom minimal wrappers.
- [Grade Tests](.agents/skills/grade-tests/SKILL.md) — _skill_ — Grade a curated list of test methods and produce a compact, PR-comment-friendly report: one row per test method with a letter grade, a score band, and a one-line note explaining the grade. The skill **does not discover tests on its own** — the caller (typically a PR automation workflow or a human reviewer holding a specific list) provides the test methods to grade.
- [MSTest v1/v2 -> v3 Migration](.agents/skills/migrate-mstest-v1v2-to-v3/SKILL.md) — _skill_ — Migrate a test project from MSTest v1 (assembly references) or MSTest v2 (NuGet 1.x-2.x) to MSTest v3. MSTest v3 is **not binary compatible** with v1/v2 -- libraries compiled against v1/v2 must be recompiled.
- [MSTest v3 -> v4 Migration](.agents/skills/migrate-mstest-v3-to-v4/SKILL.md) — _skill_ — Migrate a test project from MSTest v3 to MSTest v4. The outcome is a project using MSTest v4 that builds cleanly, passes tests, and accounts for every source-incompatible and behavioral change. MSTest v4 is **not binary compatible** with MSTest v3 -- any library compiled against v3 must be recompiled against v4.
- [MTP Hot Reload for Iterative Test Fixing](.agents/skills/mtp-hot-reload/SKILL.md) — _skill_ — Set up and use Microsoft Testing Platform hot reload to rapidly iterate fixes on failing tests without rebuilding between each change.
- [Migrate Static to Wrapper](.agents/skills/migrate-static-to-wrapper/SKILL.md) — _skill_ — Perform mechanical, codemod-style replacement of static dependency call sites with calls to injected wrapper interfaces or built-in abstractions. Operates on a bounded scope (single file, project, or namespace) so migrations can be done incrementally.
- [Run .NET Tests](.agents/skills/run-tests/SKILL.md) — _skill_ — Detect the test platform and framework, run tests, and apply filters using `dotnet test`.
- [Test Analysis Extensions](.agents/skills/test-analysis-extensions/SKILL.md) — _skill_ — This skill provides access to per-language reference files used by the polyglot test analysis skills. Call this skill to get the list of available extension files, then read the one matching the target codebase's language and test framework.
- [Test Anti-Pattern Detection](.agents/skills/test-anti-patterns/SKILL.md) — _skill_ — Quick, pragmatic analysis of test code in any supported language for anti-patterns and quality issues that undermine test reliability, maintainability, and diagnostic value.

- [Test Gap Analysis via Pseudo-Mutation](.agents/skills/test-gap-analysis/SKILL.md) — _skill_ — Analyze production code in any supported language by reasoning about hypothetical mutations and checking whether existing tests would catch them. This reveals blind spots where tests pass but would continue to pass even if the code were broken.
- [Test Platform and Framework Detection](.agents/skills/platform-detection/SKILL.md) — _skill_ — Determine **which test platform** (VSTest or Microsoft.Testing.Platform) and **which test framework** (MSTest, xUnit, NUnit, TUnit) a project uses.
- [Test Smell Detection](.agents/skills/test-smell-detection/SKILL.md) — _skill_ — Deep formal audit of test code in any supported language using an academic test smell taxonomy. Detects symptoms of bad design or implementation decisions that make tests harder to understand, more fragile, less effective at catching bugs, or more expensive to maintain. Produces a severity-ranked report with specific locations and actionable fixes.
- [Test Trait Tagging](.agents/skills/test-tagging/SKILL.md) — _skill_ — Analyze an existing test suite in any supported language and apply a standardized set of trait tags to each test method, giving teams visibility into their test distribution (positive vs. negative, critical-path coverage, smoke tests, etc.).
- [VSTest -> Microsoft.Testing.Platform Migration](.agents/skills/migrate-vstest-to-mtp/SKILL.md) — _skill_ — Migrate a .NET test solution from VSTest to Microsoft.Testing.Platform (MTP). The outcome is a solution where all test projects run on MTP, `dotnet test` works correctly, and CI/CD pipelines are updated.
- [Writing MSTest Tests](.agents/skills/writing-mstest-tests/SKILL.md) — _skill_ — Help users write effective, modern unit tests with MSTest 3.x/4.x using current APIs and best practices.
- [xUnit -> MSTest Migration](.agents/skills/migrate-xunit-to-mstest/SKILL.md) — _skill_ — Migrate a .NET test project from xUnit.net (v2 or v3) to MSTest v4. The outcome is a project that:
- [xunit.v3 Migration](.agents/skills/migrate-xunit-to-xunit-v3/SKILL.md) — _skill_ — Migrate .NET test projects from xUnit.net v2 to xUnit.net v3. The outcome is a solution where all test projects reference `xunit.v3.*` packages, compiles cleanly, and all tests pass with the same results as before migration.
