Testing

Analyze a codebase to understand what tests it needs, audit what it already has, and execute a plan to close the gap. Philosophy: understand the code's testing requirements independently before looking at existing tests — prevents anchoring bias.

When to Use

Invoke this skill when:

• Adding test coverage to an under-tested codebase
• Reviewing and improving existing test quality
• Starting work on a new module and wanting thorough test design upfront
• Auditing test coverage to find gaps, especially edge cases and boundary conditions
