content-humanize — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited content-humanize (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

AI-generated text has measurable signatures that readers and search engines detect. This skill encodes the science behind those signals, a scoring diagnostic across 8 dimensions, and a 7-pass rewrite technique for eliminating them. The goal isn't evasion — it's quality. Human-written articles get 5.44x more traffic and hold reader attention 41% longer.
| Signal | AI pattern | Human pattern |
|---|---|---|
| Perplexity | ~21 (predictable word choices) | ~36 (unexpected, domain-specific vocabulary) |
| Burstiness | Uniform sentence lengths (15–25 words) | Dramatic variation — fragments to 40-word sentences |
| Vocabulary | 50+ dead words/phrases at 5–10× frequency | Natural, specific, domain-appropriate |
| Contractions | Absent or sparse | Constant — "don't", "it's", "won't" |
| Grammar | Perfect throughout | Natural breaks — "And", "But", fragments, asides |
| Voice | Detached, encyclopedic | First-person, opinionated, emotionally varied |
| Structure | Parallel sections, equal lengths, formulaic | Deliberately unequal, unpredictable |
| Transitions | "Furthermore", "Moreover", "Additionally" | Absent, or "But.", "So.", "The catch?" |
Google's March 2026 update amplified "Experience" — content demonstrating genuine first-hand experience outranks comprehensive but impersonal content. 96% of AI Overview citations come from sources with strong E-E-A-T signals.

#### 1. Perplexity (Word-Level Unpredictability)
#### 2. Burstiness (Sentence-Level Variation)
#### 3. Vocabulary Hygiene Count every instance of dead vocabulary (see content-voice skill for full lists). Scoring: 0 hits = 10, 1–3 = 7, 4–8 = 4, 9+ = 1.
Also flag formal overreach: "utilize" (use), "facilitate" (help), "demonstrate" (show), "commence" (start), "culminate" (end), "subsequent" (next), "prior to" (before), "in order to" (to), "serves as" (is).
#### 4. Contraction Density
#### 5. Grammatical Humanity
#### 6. Voice & Personality (carries the E-E-A-T "Experience" load in 2026)
#### 7. Structural Unpredictability
## Headers, 3+ bullet points, or bold mid-sentence reads as AI regardless of word choice. Long articles can use structure when it serves reading; replies, comments, and short posts must be prose unless the surrounding chain uses markdown. Score down hard for short-form content with templated structure#### 8. Transition Quality

### Dead Word Inventory
[List every flagged word/phrase with location]Apply section by section, in order. Preserve every fact, citation, and data point — rewrite the voice, not the content.
Pass 1: Vocabulary — Replace every dead word, dead transition, dead phrase, and formal overreach. Use the simplest natural word. Don't replace with another AI-sounding synonym — use what a human expert in this field would actually say.
Pass 2: Contractions — Convert every uncontracted form unless it's deliberate emphasis. "Do not touch this" (emphasis) is fine. "It does not appear to be the case" → "It doesn't look like it."
Pass 3: Rhythm — Rebuild sentence lengths for burstiness. Find runs of 3+ similar-length sentences: break one into a fragment, merge two into a long flowing one. After any sentence >25 words, follow with one <8 words. Insert a one-sentence paragraph between dense ones.
Pass 4: Transitions — Kill every formulaic transition. Replace with nothing (just start the next idea), or: "But.", "So here's the thing.", "The catch?", "And yet —", "Which brings up something interesting."
Pass 5: Grammar humanity — Start 2–3 sentences per section with "And" or "But". Add 1–2 parenthetical asides per major section. Use at least one fragment per section. Remove all trailing participle phrases — rewrite as separate sentences. Remove all "not just X, but also Y" constructions. Remove semicolons connecting simple phrases.
Pass 6: Voice injection — At least one first-person observation per major section (if content type allows). At least one opinion or position taken. At least one moment of specificity: a named tool, person, date, or publication. At least one emotional beat: enthusiasm, skepticism, surprise, frustration.
Pass 7: Structure — Make section lengths deliberately unequal. Vary paragraph openers (question, example, continuation — not always topic sentence). If the conclusion recaps, rewrite to end with a question, prediction, or callback. If subheadings are generic, inject personality. Kill synonym rotation — pick the best word and stick with it.
AI writes:
"Digital marketing has evolved significantly over the past decade. Companies now utilize multiple channels to reach their audiences. Social media platforms offer unique opportunities for engagement. Content marketing remains a powerful strategy for building trust."
Human writes:
"Digital marketing looks nothing like it did ten years ago. Nothing. The channels alone — social, search, email, video, podcasts, influencer partnerships — would've seemed absurd in 2014. And here's what nobody tells you: most companies are still figuring it out, throwing budget at whatever platform had a good case study last quarter."
What changed: Specific over abstract. Fragments for punch. Contractions throughout. First-person energy. Unexpected vocabulary. Dramatic rhythm shifts. No dead words.
