regression-check

What problem does it solve?

This Skill prevents new code changes from breaking existing functionality, a common source of user frustration and development rework.

Core Features & Use Cases

• Impact Analysis: Systematically identifies all parts of the codebase potentially affected by a change.
• Targeted Testing: Executes relevant tests (unit, integration, e2e) on affected modules.
• Regression Detection: Differentiates between actual regressions and incorrect test expectations.
• Use Case: After a developer modifies a core authentication module, this Skill ensures that login, registration, and password reset functionalities (which rely on the authentication module) remain fully operational.

Quick Start

Run the regression-check skill to verify that recent code modifications have not introduced any unintended side effects.
