Guides the agent in designing .NET applications and libraries that manage DDD entities and aggregates using Deveel.Repository and its Entity Manager. Use this skill when aggregate boundaries, validation, creation, mutation, and deletion workflows must be orchestrated consistently around rich domain models.

Scans .NET code for ~50 performance anti-patterns across async, memory, strings, collections, LINQ, regex, serialization, and I/O with tiered severity classification. Use when analyzing .NET code for optimization opportunities, reviewing hot paths, or auditing allocation-heavy patterns.

Automated, project-wide code coverage and CRAP (Change Risk Anti-Patterns) score analysis for .NET projects with existing unit tests. Auto-detects solution structure, runs coverage collection via `dotnet test` (supports both Microsoft.Testing.Extensions.CodeCoverage and Coverlet), generates reports via ReportGenerator, calculates CRAP scores per method, and surfaces risk hotspots — complex code with low test coverage that is dangerous to modify. Use when the user wants project-wide coverage analysis with risk prioritization, coverage gap identification, CRAP score computation across an entire solution, or to diagnose why coverage is stuck or plateaued and identify what methods are blocking improvement. DO NOT USE FOR: targeted single-method CRAP analysis (use crap-score skill), writing tests, running tests without coverage collection, applying test filters, producing TRX reports, or troubleshooting test execution (use run-tests for all of these).

Guides the agent in structuring a custom .NET framework composed of reusable libraries for community consumption. Use this skill when asked to design or reorganize solution layout, package boundaries, versioning, and distribution for multi-library frameworks.

Optimize Entity Framework Core queries by fixing N+1 problems, choosing correct tracking modes, using compiled queries, and avoiding common performance traps. Use when EF Core queries are slow, generating excessive SQL, or causing high database load.

Guides the agent in structuring xUnit test projects and solutions for .NET class libraries. Use this skill when setting up a new test project, organizing the test folder layout, configuring shared build properties via Directory.Build.props, selecting xUnit and coverage packages per target framework, or establishing MSBuild conventions for test solutions.

Guides the agent in writing, naming, and organizing xUnit tests for .NET class libraries. Use this skill when asked to add or refactor tests, write unit or integration tests, set up fixtures or traits, organize test data with Bogus, or apply AAA structure and naming conventions to test methods.
