How to install work-humanizer in Claude Code

What it does

When you ask an AI to make a text sound more human, it often changes what the text says. A polite 'we will look into it' can become a promise, or an apology appears where you only meant to acknowledge a problem. At work, those small changes matter.

work-humanizer is a writing skill built for that situation. It first lists the facts in your draft and how certain each one is, then writes the text again in a natural voice while keeping every claim at the same strength.

If the draft is too generic, it can switch to an interview mode and ask you a few short questions about the real example, number or opinion that is missing. You can also give it your own notes or a voice memo transcript and it builds the text from those.

Example prompts

"Use work-humanizer on this: <paste your email>"
"Use work-humanizer on this and interview me first: <paste draft>"
"Use work-humanizer on docs/launch-post.md"
"Here are my notes from the call; use work-humanizer to turn them into a short update for the team"

How to install

$ npx skills add phuryn/work-humanizer

How to use it

Type 'Use work-humanizer on this:' and paste your draft. Add 'and interview me first' when the text is missing real details.

Check it works

Ask the assistant which skills it has; work-humanizer should be listed. The README also lets you run the checker yourself with python skills/work-humanizer/check.py draft.md from a copy of the repo.

Common problems

The assistant does not use the skill — skills load when a session starts — close the assistant, open it again in your project folder and ask again.

What to watch out for

An optional check.py script runs on your computer if the assistant decides to use it
It does not make text pass AI detectors; the README says so

Technical details of the test

Date: 13 Oct 2026
Method: Intake sandbox run on 2026-10-13 in a clean container with no account: cloned the repository and checked its skill, agent and plugin files, ran "npx -y skills --help".

Checked again on 13 Oct 2026

Alternatives

Humanizer — the better-known humanizer skill; rewrites more freely
Marketing Skills — copywriting playbooks rather than a rewrite tool
