What problem does it solve?

This Skill ensures your test suite is robust enough to catch actual bugs by intentionally introducing small defects into your code and verifying that tests fail as expected.

Core Features & Use Cases

• Automated Mutation: Intelligently introduces mutations (e.g., logic flips, guard removals) into your source code.
• Test Verification: Runs targeted tests to see if they catch the introduced mutations.
• Coverage Gaps: Identifies and reports surviving mutations, highlighting weaknesses in your test coverage.
• Use Case: After implementing a new feature, run this skill to confirm that your existing tests would have caught common developer errors like incorrect boundary conditions or faulty logic.

Quick Start

Run mutation testing on the src/services/payment.py file.
