It bundles the Microsoft.AITools.BinlogMcp MCP server, which lets the skills query a.binlog through structured tools instead of parsing text logs. See the upstream dotnet-msbuild plugin for the source. The binlog MCP server is a.NET tool run from NuGet. Upstream launches it with dotnet dnx; this power uses ndx (native dotnet execute) instead, a drop-in, Native-AOT-compiled runner with the same PACKAGE[@VERSION] identity and restore flags. Cached startup drops from roughly half a second to tens of milliseconds, which matters for a server the agent spawns repeatedly. From the project README, punctuation lightly normalized. Full text: https://raw.githubusercontent.com/gitfool/kiro-dungeon/HEAD/dotnet-msbuild/README.md ## Skills - binlog-failure-analysis: Analyze MSBuild binary logs to diagnose build failures. USE FOR: build errors that are unclear from console output, diagnosing cascading failures across multi-project builds, tracing MSBuild target execution order, and generally any MSBuild build issues. Requires an existing.binlog file. DO NOT USE… - binlog-generation: Generate MSBuild binary logs (binlogs) for build diagnostics and analysis. USE FOR: adding /bl:{} to any dotnet build, test, pack, publish, or restore command to capture a full build execution trace, prerequisite for binlog-failure-analysis and build-perf-diagnostics skills, enabling post-build inv… - build-parallelism: Diagnose and fix under-parallelized MSBuild builds. USE WHEN a multi-project solution build is slower than expected, doesn't speed up when you add cores, pegs a single core while others idle, or you want to know why `-m` isn't helping. Note: `/maxcpucount` default is 1 (sequential): always pass `-m… - build-perf-baseline: Establish build performance baselines and apply systematic optimization techniques. USE FOR: diagnosing slow builds, establishing before/after measurements (cold, warm, no-op scenarios), applying optimization strategies like static graph builds, artifacts output, and dependency graph trimming. Star… - build-perf-diagnostics: Diagnose MSBuild build performance bottlenecks using binary log analysis. USE FOR: identifying why builds are slow by analyzing binlog performance summaries, detecting ResolveAssemblyReference (RAR) taking >5s, Roslyn analyzers consuming >30% of Csc time, single targets dominating >50% of build tim… - build-perf: Agent for diagnosing and optimizing MSBuild build performance. Runs multi-step analysis: generates binlogs, analyzes timeline and bottlenecks, identifies expensive targets/tasks/analyzers, and suggests concrete optimizations. Invoke when builds are slow or when asked to optimize build times. - check-bin-obj-clash: Detects MSBuild projects with conflicting OutputPath or IntermediateOutputPath. USE FOR: builds failing with 'Cannot create a file when that file already exists', 'The process cannot access the file because it is being used by another process', intermittent build failures that succeed on retry, or… - copy-to-output-directory: Choosing an MSBuild CopyToOutputDirectory / CopyToPublishDirectory mode: Never, PreserveNewest, Always, and IfDifferent (MSBuild 17.13+), plus $(SkipUnchangedFilesOnCopyAlways). USE FOR: removing the per-build Always copy perf hit; resetting output files mutated between builds. DO NOT USE FOR: gene… - directory-build-organization: Guide for organizing MSBuild infrastructure with Directory.Build.props, Directory.Build.targets, Directory.Packages.props, and Directory.Build.rsp. USE FOR: structuring multi-project repos, centralizing build settings, implementing NuGet Central Package Management (CPM) with ManagePackageVersionsCe… - eval-performance: Guide for diagnosing and improving MSBuild project evaluation performance. USE FOR: builds slow before any compilation starts, high evaluation time in binlog analysis, expensive glob patterns walking large directories (node_modules,.git, bin/obj), deep import chains (>20 levels), preprocessed outpu… - extension-points: Guide for MSBuild extensibility: CustomBefore/CustomAfter hooks, wildcard imports with alphabetic ordering, import gating with control properties, NuGet package build extension layout (build/buildTransitive), and the MicrosoftCommonPropsHasBeenImported guard. USE FOR: diagnosing and fixing MSBuild… - including-generated-files: Fix MSBuild targets that generate files during the build but those files are missing from compilation or output. USE FOR: generated source files not compiling (CS0246 for a type that should exist), custom build tasks that create files but they are invisible to subsequent targets, globs not capturin… - incremental-build - item-management - msbuild-antipatterns - msbuild-code-review - msbuild-expert - msbuild-modernization - msbuild-server - property-patterns - resolve-project-references - target-authoring Descriptions come from the frontmatter of each SKILL.md, punctuation lightly normalized. ## MCP servers - binlog: transport: stdio; command: ndx Microsoft.AITools.BinlogMcp --prerelease Read from the plugin's own mcp.json.
