Install
/plugin marketplace add blader/humanizer
/plugin install humanizer@humanizerOur take
Packaged as a skill that works in Claude Code (2.1.142 or newer for the plugin, otherwise `npx skills add blader/humanizer --global --agent claude-code`), Codex, Claude.ai, and other agents via the Skills CLI. The README states it edits for human readers, not to evade AI detectors, and that detectors still flag most of its output. It is designed not to invent facts and asks for missing details instead; MIT licensed and actively maintained.
