+description: >-
+  Mutation testing for Go. Applies code mutations (arithmetic, branch, expression,
+  loop, statement, concurrency, and more) and checks whether tests catch them.
+  Reports a mutation score index (MSI) with CI quality gates, per-test filtering,
+  parallel execution, and JSON output designed for LLM consumption.
