Agent skill that removes signs of AI-generated writing from text
Humanizer is a portable agent skill implemented as Markdown that removes signs of AI-generated writing from text to make it sound more natural and human. The skill identifies and rewrites 33 patterns of AI-generated language drawn from Wikipedia's guide to signs of AI writing, covering content issues like significance inflation and vague attributions, language patterns such as copula avoidance and synonym cycling, style problems including em-dash overuse and title-case headings, and communication markers like chatbot artifacts. It can run in any agent harness that supports skill-style instructions—including Claude Code, Codex, and other compatible agents—and is designed to be cross-harness portable with no build step required. The project includes optional Claude Code plugin packaging and installation via the cross-agent Skills CLI, and optionally supports voice calibration to match a user's personal writing style.
