Included Skills2

supercovskills/supercov/SKILL.md

Measures test coverage and code quality in a repository with the supercov CLI, and turns what it finds into small, focused tests or fixes. Use when the user asks to add or improve tests, find untested code or raise coverage, or find what to refactor. Works with JavaScript, TypeScript, Python, Ruby, Rust, Go, Java and Kotlin projects.

supercov-securityskills/supercov-security/SKILL.md

Scans a repository's source for security vulnerabilities with the supercov CLI, pointing to the line of each finding and mapping it to CWE classes. Use when the user asks for a security scan or audit, whether code is secure, or to find vulnerabilities, injection, hardcoded secrets or other insecure code.
