Verify — Test Validation

Overview

Test validation skill covering DIM-4 (Test Fidelity) and DIM-3 (Contracts) from the backend quality dimension taxonomy. Verify finds the gap between what your tests claim to prove and what they actually exercise — the space where bugs hide behind passing suites.

This skill focuses on two complementary concerns:

• Test Fidelity (DIM-4): Do tests exercise actual production behavior, or do they test a parallel universe of mocks and test-only wiring?
• Contracts (DIM-3): Do schemas, types, and API boundaries stay in sync between declaration and usage?

Triggers

Activate this skill when:

• Evaluating test suite health after a milestone
• A bug was found that existing tests should have caught
• Reviewing test quality during code review
• Investigating why tests pass but production breaks
• Checking schema/contract integrity after API changes
