Grab SKILL.md below, then drop it into ~/.claude/skills/stay-human/SKILL.md (or just open it and paste the contents into any Claude chat).

Catches the AI tells in your writing that a detector actually reads: the structure, not the words. Built from the StoryScope study (arXiv 2604.03136, University of Maryland + Google DeepMind), which told human from AI writing 93% of the time from narrative structure alone, even after every surface tell (em dashes, vocabulary) was edited out.

You can humanise the words. You can't humanise the structure. This fixes the structure.

How to add this to Claude (pick one)

1. Fastest, paste into a chat. Open Claude, paste this whole page, and say: "Use this as a skill. Here's my draft: …" Claude runs the audit and rewrite.

2. Claude Project (reusable). Create a Project, add this page to the Project knowledge or custom instructions. Every chat in that Project can now run stay-human.

3. Claude Code / Cowork (installed skill). Save this as ~/.claude/skills/stay-human/SKILL.md (create the folders). It loads automatically. Then say "run stay-human on this".

That’s the first part. The rest of this guide is free too.
