humanizer

humanizer is a skill for Claude Code from kouroshez/coding-os. It costs 154 tokens per session (2,751 once invoked), scanned A, original, Apache-2.0.

A writing aid that removes common signs of AI-generated prose while keeping the original meaning. It is intended for text that people will read outside the code repository.

In plain words
What is it for?
Editing README files, release notes, announcements, blog posts, forum posts, pull-request descriptions, and landing-page copy before publishing.
Why use it?
It helps avoid writing that sounds artificial and may distract readers from the content.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

humanizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 27d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Humanizer

Rewrite AI-sounding prose so it reads like the writer, without changing what it says.

The failure this prevents is not embarrassment. It is that a reader who smells generated text stops evaluating the argument and starts evaluating the author — so a correct, well-evidenced claim gets discarded on style. Published prose that trips those signals costs the credibility of everything it carries.

The seam — this skill vs technical-writing

They run in sequence and must not fight:

technical-writing humanizer
Owns structure, altitude, accuracy, the doc-header contract sentence-level texture and rhetoric
Asks is it correct, findable, and at the right altitude? does it read like a person wrote it?
Runs while drafting on the finished draft, before it ships

Run technical-writing first. A humanized draft that is structurally wrong is still wrong.

Non-negotiables

  1. Keep every claim. Shorten dull parts, expand useful ones, merge or split paragraphs — but do not lose information. The exception is a pattern below that requires removal (unsupported importance, vague sources, invented context, unraised objections, fake alternatives, generic endings). Removing under one of those is correct, not a lost claim.
  2. Invent nothing. No fact, name, number, date, quote, or citation that the source or the user did not supply. If a sentence needs a missing detail, ask for it or write a simpler sentence.
  3. Never manufacture humanity. Do not add fake opinions, staged reactions, invented anecdotes, or fabricated specificity to make prose feel personal. That produces a different lie, not a human voice. Real voice comes from the writer's own material.
  4. Never claim to detect AI. In a review, report the specific patterns you found with file and line. Do not assign an "AI score" or assert that a model wrote something — you cannot know, and the claim is unfalsifiable.
  5. Match the writer's voice over these rules. If the user supplies a writing sample, read it first: sentence length, word choice, paragraph openings, punctuation, repeated phrases. Match those habits. A sample that uses em dashes keeps them; §14 is then not a ban.
  6. Leave good prose alone. Minimum effective edit. Normalizing already-clear writing is a diff-discipline failure (Rule 22).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
