Identify the minimum set of tests giving maximum coverage after a system change. Use this skill whenever the user mentions test selection, regression suite, coverage, test minimization, impacted tests, set cover, suite runtime, or is working with pytest-cov, Bazel, JaCoCo, even if they never say "regression suite optimization" explicitly. Routes live lookups through the Test-Coverage-Optimizer endpoint. Do not use it for unrelated application feature work or general coding questions.
