Description
code-simplification is an agent skill from Addy Osmani's agent-skills collection for simplifying code for clarity while keeping its behavior exactly the same. The skill is inspired by the Claude Code Simplifier plugin and adapted as a model-agnostic, process-driven skill for any AI coding agent. Its goal is not fewer lines but code that is easier to read, understand, modify and debug. Every simplification must pass one test: would a new team member understand this faster than the original? The skill applies once a feature works and its tests pass, but the implementation feels heavier than it needs to be. It also applies during a code review that flags readability or complexity, when code has deeply nested logic, long functions or unclear names, when refactoring code written under time pressure, when consolidating related logic spread across files, and after merged changes have introduced duplication or inconsistency. The skill lists cases where it should not be used. It is listed on skills.sh, with its security audit results shown there. It suits developers who want a careful refactor that keeps working code working.…
