Simplify

Use this skill to improve changed code without changing intended behavior. It is an independently authored, repository-native semantic adaptation of the four-angle /simplify workflow:

/simplify -> 4 cleanup agents in parallel -> apply the fixes

This adaptation does not claim exact parity with a particular Claude Code package version and does not reproduce Anthropic prompt text. The official npm package is used only for version and package metadata; its compiled contents are proprietary and are not treated or redistributed as readable prompt source. Provenance was reviewed on 2026-09-16 using that metadata and the readable secondary Piebald reference at commit c10ea52363b3fce1ebfc355565412711e9e82bc1. That reference identifies the four-angle shape as introduced in Claude Code 2.1.154; its workflow remained behaviorally unchanged through the v2.1.273 snapshot.
