Apply Martin Fowler-inspired enterprise architecture rules when choosing layers, service layers, transaction scripts, domain models, repositories, mappers, or DTOs. Helps structure enterprise applications with proven patterns.

Apply Martin Fowler-inspired refactoring rules to improve existing code structure while preserving observable behavior. Covers code smells, small safe refactoring steps, test-backed cleanup, and separating refactoring from feature changes.

This skill applies Refactoring.Guru-inspired rules for diagnosing code smells and selecting appropriate refactoring techniques. It helps preserve behavior while avoiding uncontrolled redesign. Before making design or code decisions, read the mini rules first. Use the full guide only as a deeper reference when needed. It ensures targeted cleanup without over-engineering.

Apply Michael T. Nygard-inspired production reliability rules when designing failure handling, timeouts, retries, circuit breakers, observability, or deployment behavior.

Apply pragmatic programming rules inspired by Hunt and Thomas to improve engineering judgment, feedback loops, DRY knowledge, orthogonality, automation, and adaptability. Use this skill for design and code decisions requiring pragmatic engineering tradeoffs.

Apply Michael Feathers-inspired rules to safely modify hard-to-test legacy code using characterization tests, seams, sprout methods, or wrap methods. Ideal for risky changes, missing tests, dependency breaking, and incremental risk reduction in software maintenance.
