Agent Skills: code-simplifier

Use this skill after writing or modifying code to simplify it — reduces complexity, eliminates redundancy, and improves naming while preserving exact behavior. Trigger after implementing a feature, after a refactor, or when asked to "clean up this code", "simplify this", "make this more readable", or "reduce complexity". Also use when code feels too nested, verbose, or hard to follow. For removing dead code and unused dependencies with detection tools (knip, ts-prune, deadcode), use refactor-cleaner instead.
