Searchable MCP and AITool gateway for .NET, built on Microsoft.Extensions.AI with embedding-based tool discovery, lexical fallback, and unified execution
Skill Claude CodeCodex
Use the open-source free Meziantou.Analyzer package for design, usage, security, performance, and style rules in .NET. Use when a repo wants broader analyzer coverage with a single NuGet package.
Skill Claude CodeCodex
Write, run, or repair .NET tests that use MSTest. Use when a repo uses MSTest.Sdk, MSTest, [TestClass], [TestMethod], DataRow, or Microsoft.Testing.Platform-based MSTest execution.
Skill Claude CodeCodex
Use the open-source free NetArchTest.Rules library for architecture rules in .NET unit tests. Use when a repo wants lightweight, fluent architecture assertions for namespaces, dependencies, or layering.
Skill Claude CodeCodex
Use the free official .NET diagnostics CLI tools for profiling and runtime investigation in .NET repositories. Use when a repo needs CPU tracing, live counters, GC and allocation investigation, exception or contention tracing, heap snapshots, or startup diagnostics without GUI-only tooling.
Skill Claude CodeCodex
Set up or refine open-source .NET code-quality gates for CI: formatting, .editorconfig, SDK analyzers, third-party analyzers, coverage, mutation testing, architecture tests, and security scanning. Use when a .NET repo needs an explicit quality stack in AGENTS.md, docs, or pipeline YAML.
Skill Claude CodeCodex
Use the open-source free QuickDup clone detector for .NET repositories. Use when a repo needs duplicate C# code discovery, structural clone detection, DRY refactoring candidates, or repeatable duplication scans in local workflows and CI.
Skill Claude CodeCodex
Use the open-source free ReportGenerator tool for turning .NET coverage outputs into HTML, Markdown, Cobertura, badges, and merged reports. Use when raw coverage files are not readable enough for CI or human review.
Skill Claude CodeCodex
Use the free official JetBrains ReSharper Command Line Tools for .NET repositories. Use when a repo wants powerful jb inspectcode inspections, jb cleanupcode cleanup profiles, solution-level .DotSettings enforcement, or a stronger CLI quality gate for C# than the default SDK analyzers alone.
Skill Claude CodeCodex
Use the open-source free Roslynator analyzer packages and optional CLI for .NET. Use when a repo wants broad C# static analysis, auto-fix flows, dead-code detection, optional CLI checks, or extra rules beyond the SDK analyzers.
Skill Claude CodeCodex
Use the open-source free Stryker.NET mutation testing tool for .NET. Use when a repo needs to measure whether tests actually catch faults, especially in critical libraries or domains.
Skill Claude CodeCodex
Use the open-source free StyleCop.Analyzers package for naming, layout, documentation, and style rules in .NET projects. Use when a repo wants stricter style conventions than the SDK analyzers alone provide.
Skill Claude CodeCodex
Write, run, or repair .NET tests that use TUnit. Use when a repo uses TUnit, [Test], [Arguments], source-generated test projects, or Microsoft.Testing.Platform-based execution.
Skill Claude CodeCodex
Write, run, or repair .NET tests that use xUnit. Use when a repo uses xunit, xunit.v3, [Fact], [Theory], or xunit.runner.visualstudio, and you need the right CLI, package, and runner guidance for xUnit on VSTest or Microsoft.Testing.Platform.
Skill Claude CodeCodex
Primary entry skill for C# and .NET tasks. Detect the repo's language version, test runner, quality stack, and architecture rules; route to the right .NET subskills; and run the repo-defined post-change quality pass after any code change. Use when the user asks to implement, debug, review, or refactor .NET code, or…
Skill Claude CodeCodex
Create or update a feature spec under docs/Features/ with business rules, user flows, system behaviour, verification, and Definition of Done. Use when the user asks for a feature spec, executable requirements, acceptance criteria, behaviour documentation, or a pre-implementation plan for non-trivial behaviour changes.
Skill Claude CodeCodex
Plan a human review for a large AI-generated code drop by reading the target area, tracing the natural user and system flows, identifying the riskiest boundaries, and prioritizing the files a human should inspect first. Use when the codebase is too large to review line-by-line and you need a practical review sequence…
Skill Claude CodeCodex
Apply ML/AI project delivery guidance for data exploration, feasibility, experimentation, testing, responsible AI, and operating ML systems. Use when the repo includes model training, inference, data science workflows, or ML-specific delivery planning.
Skill Claude CodeCodex
Capture or refine non-functional requirements such as accessibility, reliability, scalability, maintainability, performance, and compliance. Use when a feature or architecture change needs explicit quality attributes and trade-offs.
Skill Claude CodeCodex
Design or improve observability for application and delivery flows: logs, metrics, traces, correlation, alerts, and operational diagnostics. Use when a change affects runtime visibility, failure diagnosis, SLOs, or alerting.
Skill Claude CodeCodex
Apply baseline engineering security guidance: secrets handling, secure defaults, threat modelling references, and review checkpoints for auth, data flow, pipelines, and external integrations. Use when a change has security impact but does not require a full standalone AppSec engagement.
Skill Claude CodeCodex
Apply SOLID, SRP, cohesion, composition-over-inheritance, and small-file discipline to code changes. Use when refactoring large files or classes, setting maintainability limits in AGENTS.md, documenting justified exceptions, or reviewing design quality.
Skill Claude CodeCodex
Set up or refine solution-level governance for MCAF repositories: root and project-local AGENTS.md, rule precedence, solution topology, skill routing, and maintainability-limit policy placement. Use when bootstrapping a repo, restructuring a multi-project solution, or tightening agent rules.
Skill Claude CodeCodex
Set or refine source-control policy for repository structure, branch naming, merge strategy, commit hygiene, and secrets-in-git discipline. Use when bootstrapping a repo, tightening PR flow, or documenting branch and release policy.
Skill Claude CodeCodex
Add or update automated tests for a change using the repository’s verification rules in AGENTS.md. Use when implementing a feature, bugfix, refactor, or regression test; prefer stable integration/API/UI coverage and pull deeper test strategy from the bundled references.
