The Pragmatic Programmer principles for code quality enforce clear boundaries, testable contracts, and disciplined evolution to reduce duplicate knowledge and hard-to-maintain code. They provide concrete guidelines for software design, refactoring, and modular development.

To apply the DRY principle and reduce code duplication, ensure a single source of truth for knowledge and behavior across your software systems. This minimizes redundant logic and prevents maintenance issues during code reviews and refactoring tasks.

Orthogonality improves software maintainability by promoting independent components with low cross-cutting dependencies. This design principle ensures that changes in one area of the codebase do not inadvertently affect or break unrelated modules.

Use tracer bullets and pragmatic paranoia when starting with end-to-end slices and designing by contract. These development practices enforce validation and fail-fast checks early in the process to catch integration issues before they escalate.

Yes, you can use these pragmatic coding guidelines during team code reviews to prevent creeping complexity and ensure changes remain safe and reversible. They enforce design by contract and orthogonality as guardrails for development practices.
