humanizer

humanizer is a skill for Claude Code, Codex from Natsummerance/readMD. It costs 61 tokens per session (6,633 once invoked), scanned A, a copy of humanizer, MIT.

An editing aid that rewrites text with common AI-writing patterns so it sounds more natural while keeping its meaning. It addresses issues such as inflated claims, filler, repetition, vague sourcing, and chatbot-like wording.

In plain words
What is it for?
Use it to edit articles, messages, reports, or other prose that feels generic or machine-written. It can also help match the writing to the original author’s voice.
Why use it?
It removes artificial-sounding phrasing without adding facts or changing what the text says.

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 1 finding 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-package.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Humanizer: remove AI writing patterns

Rewrite AI-sounding text so it reads like the writer, not a chatbot. Do not change what it says or make up details.

The patterns below come from Wikipedia's "Signs of AI writing", maintained by WikiProject AI Cleanup.

What to do

When given text to humanize:

  1. Find AI patterns. Check the text against the patterns below.
  2. Keep every claim. You may shorten dull parts, expand useful parts, and merge or split paragraphs. Keep the information even when you change the structure.
  3. Do not invent facts. Do not add a fact, name, number, date, quote, or citation unless it comes from the source or the user. If a sentence needs a missing detail, ask for it or use a simpler sentence. You may add an opinion or reaction when the writer's voice calls for one, but you may not add a factual claim. Fiction is exempt because invented details are part of the task.
  4. Match the voice. Use the right tone for the text, such as formal, casual, or technical. Add personality only when the text and the writer call for it.

The input type controls what you return. See How to return the result. Use the same rewrite process in every mode.

Match the writer's voice

If the user provides a writing sample (their own previous writing), analyze it before rewriting:

  1. Read the sample first. Note its sentence length, word choice, paragraph openings, punctuation, repeated phrases, and transitions.
  2. Match those habits. Do not replace casual words with formal ones or remove deliberate quirks.
  3. If there is no sample, use the guidance below.

A writing sample takes priority over these style rules. If the sample uses em dashes, keep them at about the same rate. Do not apply §14 as a ban.

Add personality only when it fits

Removing AI patterns is only half the job. The result should still sound like a person.

Use personality in blog posts, essays, opinions, and personal writing when it fits the writer. Keep reference, technical, legal, and factual text neutral. Do not add opinions or first-person language where they do not belong.

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.
