humanizer

humanizer is a skill for Claude Code, Codex from eigent-ai/agent-skills. It costs 74 tokens per session (1,179 once invoked), scanned A, original, Apache-2.0.

A writing editor that finds common signs of AI-generated text and rewrites it in a more natural voice. It can also use samples of a person’s writing to match their style.

In plain words
What is it for?
It is for editing blog posts, marketing copy, and other drafts while keeping their main facts and meaning.
Why use it?
It helps when text sounds repetitive, vague, overly formal, or recognisably machine-written.

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 5d 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Overview

Detects and rewrites 29 AI writing patterns across content, language, style, and communication categories. Patterns include: significance inflation, vague attributions, copula avoidance, synonym cycling, em dash overuse, sycophantic tone, chatbot artifacts, and more. Also supports voice calibration from your own writing samples.

Source Repository


/humanize

Full 29-pattern detection and rewrite. Analyzes the input for all AI-sounding patterns, rewrites the content, then runs a second-pass "obviously AI?" audit before returning the final version.

Workflow

  1. Receive the text to humanize and any brand voice notes.
  2. Scan for all 29 patterns — flag each instance found.
  3. Rewrite the text: fix flagged patterns, preserve the core argument and facts.
  4. Run a second-pass audit: read the rewrite cold and ask "does any sentence still sound AI-generated?"
  5. Return the final rewritten text with a brief summary of the main changes made.

Example prompts

Use case Task prompt
Blog post Humanize this blog post draft. Remove any AI-sounding patterns. Preserve the core argument but make it read like a person who actually has opinions wrote it.
LinkedIn Rewrite this LinkedIn post. It currently sounds like ChatGPT wrote it. Cut the significance inflation, remove the em dashes, and make it direct.
Press release Run the 29-pattern check on this press release. Flag every AI pattern you find, then rewrite it. The brand voice is confident and plain-spoken, not corporate.

/voice-calibrate

Accepts 2–3 writing samples from the target author, extracts their stylistic fingerprint (sentence rhythm, vocabulary, punctuation habits), then applies that fingerprint to any AI-generated text.

Workflow

  1. Receive 2–3 writing samples from the target author.
  2. Analyze samples for: average sentence length, punctuation habits, vocabulary range, tonal register, structural patterns (how they open/close paragraphs), and idioms they favor.
  3. Document the fingerprint as a short style profile.
  4. Apply the fingerprint to the target AI text, rewriting to match the author's natural voice.
  5. Return the rewritten text with the style profile so it can be reused in follow-up requests.

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.
