Expert in test-first development of production-quality OpenRewrite recipes for automated code refactoring. Automatically activates when working with OpenRewrite recipe files, Java/YAML files in `src/main/java/**/rewrite/**` directories, writing tests implementing `RewriteTest`, or when users ask about recipe development, writing recipes, creating migrations, LST manipulation, JavaTemplate usage, visitor patterns, preconditions, scanning recipes, YAML recipes, GitHub Actions transformations, Kubernetes manifest updates, or code migration strategies. Guides recipe type selection (declarative/Refaster/imperative), visitor implementation, and test-driven development workflows.

Use when debugging regressions or identifying which commit introduced a bug - provides systematic workflow for git bisect with automated test scripts, manual verification, or hybrid approaches. Can be invoked from systematic-debugging as a debugging technique, or used standalone when you know the issue is historical.

Enforce mandatory npm test and npm run lint execution after every code change with no exceptions for code quality and test coverage compliance
