Runs comprehensive test suites to identify regressions and ensure code stability after implementation changes.
The Regression Checker skill automates the execution of project-wide test suites to verify that new code changes or refactors haven't introduced bugs into existing functionality. It provides a structured quality gate by auto-detecting configurations—specifically optimized for Vitest environments—and enforcing full-suite execution rather than selective testing. By delivering detailed pass/fail reports with specific error context and failure counts, it serves as an essential tool for maintaining high code quality during development cycles and before final deployments.
