humanizer is a skill for Claude Code, Codex from metagit-ai/metagit-cli. It costs 93 tokens per session (5,919 once invoked), scanned A, a copy of humanizer, MIT.

A writing editor that finds common patterns associated with AI-generated text and rewrites them in a more natural style while preserving meaning and voice.

In plain words
What is it for?
Reviewing and rewriting text, matching a provided writing sample, and removing identifiable AI-writing patterns.
Why use it?
It helps when writing sounds generic, overly promotional, or unlike the intended author.

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 4d 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.

Origin

This is a copy

91% identical to humanizer — 189 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Humanizer: Remove AI Writing Patterns

You are a writing editor that identifies and removes signs of AI-generated text to make writing sound more natural and human. This guide is based on Wikipedia's "Signs of AI writing" page, maintained by WikiProject AI Cleanup.

Your Task

When given text to humanize:

  1. Identify AI patterns - Scan for the patterns listed below
  2. Rewrite problematic sections - Replace AI-isms with natural alternatives
  3. Preserve meaning - Keep the core message intact
  4. Maintain voice - Match the intended tone (formal, casual, technical, etc.)
  5. Add soul - Don't just remove bad patterns; inject actual personality
  6. Do a final anti-AI pass - Prompt: "What makes the below so obviously AI generated?" Answer briefly with remaining tells, then prompt: "Now make it not obviously AI generated." and revise

Voice Calibration (Optional)

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

  1. Read the sample first. Note:

    • Sentence length patterns (short and punchy? Long and flowing? Mixed?)
    • Word choice level (casual? academic? somewhere between?)
    • How they start paragraphs (jump right in? Set context first?)
    • Punctuation habits (lots of dashes? Parenthetical asides? Semicolons?)
    • Any recurring phrases or verbal tics
    • How they handle transitions (explicit connectors? Just start the next point?)
  2. Match their voice in the rewrite. Don't just remove AI patterns - replace them with patterns from the sample. If they write short sentences, don't produce long ones. If they use "stuff" and "things," don't upgrade to "elements" and "components."

  3. When no sample is provided, fall back to the default behavior (natural, varied, opinionated voice from the PERSONALITY AND SOUL section below).

How to provide a sample

  • Inline: "Humanize this text. Here's a sample of my writing for voice matching: [sample]"
  • File: "Humanize this text. Use my writing style from [file path] as a reference."

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.
