Included Skills9

coverage-reportskills/coverage-report/SKILL.md

Generate a .NET code coverage report scoped to files changed in the current branch. Runs tests with coverage collection and produces filtered HTML reports.

dotnet-analyzersskills/dotnet-analyzers/SKILL.md

Run dotnet format to fix code style and analyzer diagnostics (IDE0005, CA*, SA*). Use when fixing unnecessary usings, code style violations, analyzer warnings, or verifying format compliance

dotnet-dependencyskills/dotnet-dependency/SKILL.md

This skill should be used when investigating .NET project dependencies, understanding why packages are included, listing references, or auditing for outdated/vulnerable packages.

dotnet-inspectskills/dotnet-inspect/SKILL.md

Query .NET APIs across NuGet packages, platform libraries, and local files. Search for types, list API surfaces, compare and diff versions, find extension methods and implementors. Use whenever you need to answer questions about .NET library contents.

dotnet-run-fileskills/dotnet-run-file/SKILL.md

Run script-like CSharp programs using dotnet run file.cs. Use this skill when users want to execute CSharp code directly, write one-liner scripts via stdin, or learn about run file directives.

Use when updating verified snapshots after intentional code changes, accepting new snapshots, discovering verify tests, or troubleshooting snapshot mismatches. Trigger phrases include "verify tests", "update snapshots", "accept snapshots", "verified files", ".verified.txt".

ilspy-decompileskills/ilspy-decompile/SKILL.md

Understand implementation details of .NET code by decompiling assemblies. Use when you want to see how a .NET API works internally, inspect NuGet package source, view framework implementation, or understand compiled .NET binaries.

roslyn-queryskills/roslyn-query/SKILL.md

Query .NET/C# codebases using Roslyn AST analysis via dotnet run file. Use for tracing data flow, auditing API usage, finding pattern violations, or ad-hoc codebase queries.
