codebase-refactoring

A guided pass over a codebase's three biggest maintenance costs — duplicated code, dead code, and complexity — using jscpd to find each and a strategy to fix it. Use this skill when asked to "clean up", "improve", "refactor" or "pay down tech debt in" a codebase, rather than to fix one specific bug.

Start here: measure, then prioritize

npx jscpd --health --reporters ai <path>

health 74 B (duplication 75, dead-code 72, complexity 76; 93 code lines)
