test-unit — Write tests that would notice a break
Degree of freedom: MIXED — which cases to write [HIGH freedom];
detect-then-match existing harness [LOW freedom — run exactly]. This skill
writes tests. Coverage theater / mutation score → test-mutation.
Write effective, maintainable unit tests from the project's actual framework, production error data, and current best practices.
