binlog-generation
by dotnet
"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 investigation of errors or performance. Requires MSBuild 17.8+ / .NET 8 SDK+ for {} placeholder; PowerShell needs -bl:{{}}. DO NOT USE FOR: non-MSBuild build systems (npm, Maven, CMake), analyzing an existing binlog (use binlog-failure-analysis instead)."
msbuild-antipatterns
by dotnet
"Detect and fix MSBuild anti-patterns in project and build files. USE WHEN asked to review, audit, lint, clean up, or code-review a .csproj/.vbproj/.fsproj/.props/.targets/.proj (or Directory.Build.props/.targets) file, when asked 'is this project file correct?' or 'what's wrong with my build file?', or when hunting subtle build bugs caused by how a project is authored. Each anti-pattern has a symptom and a concrete BAD→GOOD fix. DO NOT USE FOR: non-MSBuild build systems (npm, Maven, CMake), or migrating a project to SDK-style (use msbuild-modernization)."
convert-to-cpm
by dotnet
Convert .NET projects and solutions (.sln, .slnx) to NuGet Central Package Management (CPM) using Directory.Packages.props. USE FOR: converting to CPM, centralizing or aligning NuGet package versions across multiple projects, inlining MSBuild version properties from Directory.Build.props into Directory.Packages.props, resolving version conflicts or mismatches across a solution or repository, updating or bumping or syncing package versions across projects. Also activate when packages are out of sync, drifting, or inconsistent -- even without the user mentioning CPM. Provides baseline build capture, version conflict resolution, build validation with binlog comparison, and a structured post-conversion report. DO NOT USE FOR: packages.config projects (must migrate to PackageReference first) or repositories that already have CPM fully enabled.
migrate-mstest-v1v2-to-v3
by dotnet
Migrate MSTest v1/v2 projects to MSTest v3, and fix v1/v2-to-v3 breaking changes that surface after the packages are already at 3.x. USE FOR: removing v1 Microsoft.VisualStudio.QualityTools.UnitTestFramework assembly references; moving MSTest.TestFramework/TestAdapter 1.x-2.x to 3.x, the MSTest metapackage, or MSTest.Sdk; tests that broke after a 2.x-to-3.x bump -- CS0411/CS1503 on Assert.AreEqual/AreNotEqual/AreSame once the object overloads became generic, and DataRow strict type matching (1L vs 1) that builds with MSTEST0014 but fails at run time; .testsettings/LegacySettings to .runsettings (DeploymentEnabled, per-test MSTest TestTimeout); v3 timeout behavior; TFMs v3 dropped (net5.0, .NET Fx below 4.6.2, netstandard1.0). Applies even when the project already references MSTest 3.x, if a v1/v2-era setting or error remains. Keeps the current runner. DO NOT USE FOR: MSTest v4 (use migrate-mstest-v3-to-v4 next), clean v3 projects with no v1/v2 leftovers, other test frameworks, or VSTest-to-MTP.
eval-performance
by dotnet
"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 output >10K lines indicating heavy evaluation, property functions with file I/O ($([System.IO.File]::ReadAllText(...))), multiple evaluations per project. Covers the 5 MSBuild evaluation phases, glob optimization via DefaultItemExcludes, import chain analysis with /pp preprocessing. DO NOT USE FOR: compilation-time slowness (use build-perf-diagnostics), incremental build issues (use incremental-build), non-MSBuild build systems."
property-patterns
by dotnet
"MSBuild property definition patterns: conditional defaults, composition/concatenation, path normalization, trailing-slash handling, TFM detection helpers, and evaluation order. USE FOR: diagnosing and fixing property definition issues and shared-property anti-patterns in .props/.csproj; DefineConstants or NoWarn overwritten instead of appended; unconditional assignments that block project-level overrides; unquoted conditions that fail on empty properties; hardcoded paths that break cross-platform builds; setting overridable defaults; property evaluation order and last-write-wins semantics. DO NOT USE FOR: props vs targets placement (use directory-build-organization), item operations (use item-management), target structure (use target-authoring), general anti-patterns (use msbuild-antipatterns), non-MSBuild build systems."
repomix-unmixer
by daymade
Extracts files from repomix-packed repositories, restoring original directory structures from XML/Markdown/JSON formats. Activates when users need to unmix repomix files, extract packed repositories, restore file structures from repomix output, or reverse the repomix packing process.

context-discipline
by codewithmukesh
Token budget management for Claude Code sessions. Teaches how to minimize context consumption using MCP-first navigation, lazy loading, subagent isolation, and strategic file reading. Keeps Claude effective throughout long sessions by treating the 200k token window as a budget, not a dumping ground. Load this skill when context is running low, sessions feel sluggish, Claude starts forgetting earlier context, or when planning how to explore a large codebase efficiently. Keywords: "context", "tokens", "budget", "running out of context", "too many files", "large codebase", "memory".
session-management
by codewithmukesh
End-to-end session lifecycle management for .NET projects. Handles session start (load handoff, MEMORY.md, instincts, detect .NET solution), session end (capture completed work, persist learnings, write handoff), and context preservation across sessions. Load this skill when starting a new session, ending a session, when the user says "new session", "pick up where we left off", "what were we working on", "session start", "session end", "handoff", "context", "resume", or when Claude needs to bootstrap itself in an unfamiliar project.

migrate-dotnet10-to-dotnet11
by dotnet
Migrate a .NET 10 project or solution to .NET 11 and resolve all breaking changes. This is a MIGRATION skill — use it when upgrading from .NET 10 to .NET 11, NOT for writing new programs. USE FOR: upgrading TargetFramework from net10.0 to net11.0, fixing build errors after updating the .NET 11 SDK, resolving source-breaking and behavioral changes in .NET 11 runtime, C# 15 compiler, and EF Core 11, adapting to updated minimum hardware requirements (x86-64-v2, Arm64 LSE), and updating CI/CD pipelines and Dockerfiles for .NET 11. DO NOT USE FOR: .NET Framework migrations, upgrading from .NET 9 or earlier, greenfield .NET 11 projects, or cosmetic modernization unrelated to the upgrade. NOTE: .NET 11 is in preview. Covers breaking changes through Preview 3.

Use when proposals may be outdated, when checking cross-proposal conflicts, or before starting a batch of implementations. Produces a gap-analysis report, updates a priority queue file, and can auto-fix trivial issues or guide conversations for complex ones.

dox-describe
by BlackBeltTechnology
Fill the empty Purpose cells of a directory AGENTS.md tree with one-line LLM summaries (one subagent per file, plan-then-confirm, cap 50 rows/run). Use for a path-only kb dox init tree, or when asked to "describe the tree", "fill AGENTS.md purposes", or "populate the kb corpus".
reverse-spec-from-code
by BlackBeltTechnology
'Reverse-generate OpenSpec capability specs (openspec/specs/<cap>/spec.md) from code that lacks them, or reconcile an existing stale spec with --refresh, using parallel subagents. Fans out one blind generator per capability, audits each spec against the code for hallucinations, and promotes only on user confirm. Use on "generate specs from code", "backfill openspec specs", "refresh a stale spec".'
music-analysis
by BlackBeltTechnology
"Analyse a local audio file into a versioned music map (<stem>_map.json, schema music-map/1): tempo from the downbeat grid, 1-based bars, key, band levels, classed sections, drop candidates, optional stems and style tags.
