Humanizer

Agent skill removing AI writing clichés and robotic phrasing from text

Visit github.com ↗

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.

How it works

How to install and use:

  1. Download the repository zip file from GitHub (https://github.com/blader/humanizer).
  2. Navigate to Claude -> Customize (claude.ai/customize) -> Skills.
  3. Click 'Create new skills' and select 'Upload a skill'.
  4. Upload the downloaded files/folder.
  5. Once enabled, Claude will trigger the 'Check humanizer skill' on writing requests to output human-like text.
