humanize

humanize is a skill for Claude Code, Codex from richfrem/agent-plugins-skills. It costs 151 tokens per session (1,431 once invoked), scanned A, original, MIT.

A writing editor that rewrites stiff, artificial-sounding text into more natural language while preserving its meaning and intended voice.

In plain words
What is it for?
Use it to revise emails, posts, documentation, internal messages, or other text that sounds robotic.
Why use it?
It helps remove common AI-writing patterns and makes text feel more conversational and specific to its audience.

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

humanize 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 yesterday.

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

Humanize

Transform stiff, AI-flavored, or over-polished writing into something that sounds like it came from an actual person -- with a distinct voice, natural rhythm, and the small imperfections that signal authenticity.


Input Context

The user provides text to humanize. They may also provide:

  • Voice context: "write like a senior engineer", "this is for my LinkedIn"
  • Channel: email, social post, blog, Slack, internal memo
  • Tone direction: "warmer", "more direct", "less formal"

If none of these are provided, infer them from the text. Ask only if the target voice is genuinely ambiguous and would change the output significantly.

If the user has placed writing samples in references/voice-profile/my-voice.md, read that file before rewriting. It contains their preferred sentence patterns, register, and vocabulary. Apply those patterns instead of projecting a generic voice.


Phase 1: Diagnose

Before rewriting, read the text as a human editor would. Identify internally:

  1. AI fingerprints -- which structural patterns are present?
  2. What's actually being said -- strip the structure, find the real content
  3. Who should be saying it -- what kind of person, in what context?
  4. What's missing -- real writing usually has a point of view, a concrete detail, or a light edge that has been smoothed away

Do this quickly and internally. Do not narrate this to the user unless asked.

For a full catalog of AI patterns and their fixes, read: references/patterns.md


Phase 2: Rewrite

Apply these principles in order:

Voice first, fixes second. Do not just remove bad patterns. Replace them with something that has character. A human does not just avoid em dashes -- they use shorter sentences, or fragments, or a question.

One idea per sentence, usually. Most AI text over-compounds. Break it up. Short sentences are not unsophisticated -- they are confident.

Concrete over abstract. Replace vague abstractions with specifics wherever possible. "Improved performance" becomes "cut load time in half." "Valuable insights" -- name one. If there is no specific to reach for, cut the claim.

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.
