Can I use this skill with GitHub Actions?

Yes, the skill provides specific YAML configurations for GitHub Actions and Azure Pipelines, allowing you to automatically post coverage summaries and CRAP analysis directly to your Pull Requests.

What is considered a 'bad' CRAP score?

Generally, a CRAP score below 5 is excellent, 5-30 is acceptable but should be monitored, and any score over 30 is considered high-risk and should be prioritized for refactoring or additional testing.

Why does this skill require the OpenCover format?

OpenCover is used because it captures cyclomatic complexity metrics alongside line coverage. Many other formats only track coverage, which is insufficient for calculating the CRAP score.

What is a CRAP score in .NET development?

The CRAP (Change Risk Anti-Patterns) score is a metric that combines a method's cyclomatic complexity with its test coverage. A high score indicates code that is both difficult to understand and untested, making it risky to modify.

Security & Testing

Analyzes .NET code risk by calculating CRAP scores and visualizing test coverage hotspots to identify maintainability issues.

This skill automates the identification of high-risk code in .NET projects by calculating CRAP (Change Risk Anti-Patterns) scores, which combine cyclomatic complexity with test coverage data. By focusing on methods that are both complex and poorly tested, it helps developers prioritize refactoring and testing efforts where they are most needed. It provides comprehensive configuration templates for OpenCover and ReportGenerator, enabling the generation of interactive HTML reports and Risk Hotspot summaries that can be integrated directly into GitHub Actions or Azure DevOps pipelines.

Key Features

01Calculates CRAP scores to identify high-risk code patterns
