simplecov

The skill is benign with respect to security risk and aligns well with its stated purpose of enabling and guiding Ruby/Rails test coverage analysis using SimpleCov and RubyCritic. It relies on standard, well-known tooling (Bundler, gem registries) and does not require credentials, remote code execution, or data exfiltration. The data flows are limited to local test execution and report generation, with optional CI integration for enforcing thresholds. Overall, a coherent and proportionate tool for its intended domain.
