Humanizer: 40,000 Stars for Deleting the AI Smell
Humanizer is an agent skill that does exactly one thing: rewrite AI-generated text so it doesn't read like AI-generated text. It's at 40,000+ stars and added 366 today — for what is, structurally, a Markdown file. Built by blader (Siqi Chen), MIT licensed, installable via Skills CLI, the Claude Code plugin marketplace, or Claude Desktop.
The method is what makes it worth studying. It encodes 35 patterns from Wikipedia's "Signs of AI writing" list — the em-dash addiction, "it's not X, it's Y," the summary paragraph that starts with "Overall" — and runs multiple passes: rewrite without treating the original structure as sacred, check the draft against the patterns and the original claims, rewrite again. It won't invent details, leaves code and links alone, and adapts to your voice if you feed it writing samples.
Wikipedia editors spent three years cataloguing AI tells for detection. Humanizer inverts the catalog into a style guide — the detection list and the evasion tool are now the same document, and 40,000 people starred the evasion side. It's also the cleanest demo yet of the skills thesis: judgment about writing, which used to live in someone's head, packaged as a file that any agent can execute. This one file has more stars than most frameworks.
