Expose blind spots in your existing tests.
What it does
Identifies caller-visible behavior changes that existing tests could miss and supplies concrete tests to expose those gaps.
When to use it
Use to assess whether tests would catch a bug, find behavioral blind spots, or investigate surviving mutations.
How to use it
Give it an existing codebase and tests; it returns a test-strength verdict and concrete behavioral gaps, verifying mutations or adding tests only when requested.
