ce-simplify-code runs three parallel focused reviews (Reuse, Quality, Efficiency) on a specified code diff, applies their findings, and verifies behavior preservation via typecheck, lint, and scoped tests.

It targets refinement debt including duplicated utilities, dead code, hacky patterns, unnecessary wrappers, and missed concurrency or computation opportunities. The skill resolves scope from user-named files, branch diffs, or recent edits and runs before review, commit, or handoff, with particular application to AI-generated code that contains duplication and over-engineering.
