# Humanizer

> Agent skill removing AI writing clichés and robotic phrasing from text

Humanizer is an open-source agent skill designed to strip out telltale signs of AI-generated prose without altering the core meaning. Based on guidelines from Wikipedia's WikiProject AI Cleanup, it identifies 26 specific patterns such as forced triads, dramatic one-line closers, and generic buzzwords. It works across Claude, Claude Code, Codex, and other agent platforms supporting standard skills.
