humanizer

A writing-editing skill that removes common signs of machine-generated text and adds specific details, varied sentence lengths, and clearer emotional wording. It can also adapt edits to a personal writing style when given a voice reference.

In plain words
What is it for?
Use it to revise LinkedIn posts, product copy, blog drafts, or other existing text. Personal-brand mode helps check whether the revision matches a particular author’s voice.
Why use it?
It helps drafted writing sound less generic or machine-written without creating new content from nothing. It also separates style editing from research, fact-checking, and search-engine scoring.

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 D, and why

humanizer scanned grade D with 2 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 2d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/eval_voice.py, tests/test_eval_voice.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 Patterns + Inject Human Quality

Full routing notes

Removes AI writing patterns and injects human quality — specificity, burstiness, and precise emotional language. Use when editing drafted content, cleaning up LinkedIn posts, product copy, or blog content so it doesn't sound like AI. Two-phase process: Phase 1 removes 33 AI tells (significance inflation, AI vocabulary, em dash overuse, contrastive negation, vague attributions, soulless structure); Phase 2 injects humanity (sentence length variation, specificity via "what kind?" technique, precise emotional language). An optional personal-brand mode (below) adapts the two phases to a specific author's voice, using a scoreable voice-schema gate and a deterministic eval harness. Do not use for generating new content from scratch, fact-checking, SEO scoring, or research. Does not use humanizer tools (gpthuman.ai, WriteHuman) — those are detectable; this skill does structural rewriting.

Two-phase editing skill. Phase 1 removes AI tells. Phase 2 injects specificity, burstiness, and emotional precision. Clean-but-generic is still a failure — both phases are required.

Setup

Load both reference files before starting:

  1. references/patterns-reference.md — 33 AI tell patterns with before/after examples
  2. references/specificity-techniques.md — "What kind?" technique, 7 levers, Emotions Wheel

Both are mandatory. Do not skip either.


Brand Context Intake

Before editing, identify the context. If not supplied, ask:

"Which context is this for? (a) Personal brand — LinkedIn/X/blog, (b) Analytical deliverable (report/memo/brief), (c) Generic content"

Context Risk level Quality gate
Personal brand (LinkedIn/X/blog) Highest Use Personal-brand mode below (voice reference + schema gate + eval harness). Always offer 2 variations. Read-aloud test mandatory. At least one thing only the author could know.
Analytical deliverable (paired with a write-report-style caller before its humanization pass) Highest Match the register the document already uses — keep analytical clarity, strip generic AI texture. Zero em-dashes. Preserve evidence tags, codes, and cited numbers untouched — relocate, never delete.
Generic content Standard Run Phase 1 + Phase 2 only. No voice gate.

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.

humanizer is a skill published in the GitHub repository Agent-Engineer-Master/skill-engineer (8 stars, last pushed 1mo ago), licensed MIT. It adds 77 tokens to every session and 2,557 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it D with 2 findings (hidden instructions, subtle steering). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
