About this skill

What it does. Maps public inputs to returned values, exceptions, state changes and side effects, then compares them with existing assertions. It can classify gaps as killed, survived, unverified or uncovered, verify selected mutations, and add focused tests when requested.

When to use it. For behavioural blind spots and missing edge cases in existing suites. It does not cover suite organisation, coverage metrics, assertion audits, mutation tools or creating new test suites.
