What it does
A portable skill that names the specific habits — significance inflation, vague attribution, "-ing" analyses that say nothing, copula avoidance, the usual vocabulary — and shows a before and after for each, rather than vaguely asking the model to sound human. Plain Markdown, so it drops into any harness that reads skill files. It fixes phrasing, not facts, and using it to disguise AI authorship where disclosure is required is a policy problem rather than a writing one. MIT.

- It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
- Does humanizer work on a phone?
- No. It needs a computer.
- Can I use humanizer commercially?
- The licence is MIT, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
