Quality

Code Refactoring helps you safely improve code structure using a phased, test-driven approach based on Martin Fowler's methodology. Use it to reduce technical debt, eliminate code smells, and improve maintainability without changing external behavior.

Before You Build reviews product and feature ideas before implementation to identify the highest-risk assumption and the smallest validation step for MVPs, landing pages, SaaS products, internal tools, agent workflows, or major features.

Multi-Reviewer Patterns coordinates parallel code reviews across multiple quality dimensions, deduplicating findings, calibrating severity, and producing consolidated reports. Use it when organizing multi-reviewer code reviews or consolidating review results.

Parallel Debugging debugs complex issues using the Analysis of Competing Hypotheses methodology with parallel agent investigation, evidence collection, and root cause arbitration. Use it when bugs have multiple potential causes or need systematic root cause analysis.
