(\"Uncle Bob\") Martin's original **crap4clj**, and is a C# port of its Java sibling **crap4java**. --- `crap4csharp` is a standalone CRAP metric tool for C# projects, modeled after `crap4java`. It combines method cyclomatic complexity with Coverlet (Cobertura) method coverage and reports CRAP scores. On each run it deletes stale coverage artifacts, runs coverage, then analyzes the selected files. Formula `CRAP = CC^2 * (1 - coverage)^3 + CC` - `CC` is cyclomatic complexity. - `coverage` is method coverage fraction from Cobertura line counters (the .NET analog of JaCoCo `INSTRUCTION` counters). Coverage Pipeline For each invocation, per module (nearest `.sln`, else `.csproj`, else the project root): 1. Delete stale coverage artifacts: - `coverage/` 2.
