humanizer is a Claude Code skill that detects AI writing patterns and rewrites text to sound human while injecting authentic voice.
About
humanizer is a Claude Code skill that rewrites AI-generated text to sound human by detecting patterns like overused phrases, rule-of-three, em-dash overuse, and vague attributions. A developer uses it when copy sounds like ChatGPT and needs voice injected. It grades how aggressively to rewrite by context, from academic to social.
- Detects and rewrites AI writing tells (delve, testament to, em-dash overuse)
- Context-graded humanization levels from academic to social
- Statistical density checks for AI vocabulary and rule-of-three

What humanizer says it does
Transform AI-generated text into human writing by detecting patterns and injecting authentic voice.
Never remove AI phrases without also injecting personality — sterile text is still obviously AI.

What it does
Rewrite AI-generated copy to sound human by removing AI tells and injecting voice, graded by context.
Who is it for?
Blog, marketing, and social copy that needs AI tells removed and a distinct human voice.
Skip if: Academic or technical docs where structure must stay and only slop should be trimmed.
When should I use this skill?
Use when making text sound human, removing AI tells, or fixing writing that sounds like ChatGPT.
By the numbers
- 5-context humanization-level table (10-100%)
- statistical density thresholds (>3 AI words/100, >2 em dashes/paragraph)

Humanizer: AI Pattern Detection & Voice Injection
Transform AI-generated text into human writing by detecting patterns and injecting authentic voice.
NEVER
- Never remove AI phrases without also injecting personality — sterile text is still obviously AI.
- Never over-correct (random punctuation chaos !== human voice).
- Never remove ALL structure from formal or academic contexts — know what the audience expects.
- Never batch-replace AI words without checking domain context ("landscape" in CV papers may be correct terminology).
- Never fix every pattern at once — identify the 3-5 dominant patterns and address those.
Before You Edit: Diagnostic Framework
Answer these before applying any changes:
Voice assessment:
- What personality should come through? (witty, skeptical, conversational, authoritative)
- Does the text have opinions, or just facts? Human writing has stakes.
Pattern prioritization:
- Which 3-5 patterns dominate? (Don't fix everything at once)
- Should some AI-isms stay? (Formal technical docs may keep certain structures)
Rewrite philosophy:
- Am I removing patterns OR injecting personality? (Must do both)
- Does my rewrite sound like a specific human wrote it? (Not just "less AI")
Statistical density check (run before editing):
- AI vocabulary words per 100 words: >3 = heavy AI signature
- Em dashes per paragraph: >2 = structural tell
- "However" paragraph starts: >20% = AI transition overuse
- All paragraphs same length? = AI rhythm uniformity
- Every list has exactly 3 items? = rule of three addiction
Humanization Level by Context
| Context | Level | Remove | Inject Voice |
|---|---|---|---|
| Academic/Research | 10-20% | Delete slop only (delve, testament to) | Minimal — keep structure |
| Technical Docs | 30-50% | Remove promotional language, keep clarity | Light specificity: "handles edge case X" |
| Blog/Marketing | 70-90% | Remove most AI tells | Strong personality, distinct author presence |
| Social/Casual | 100% | Delete all AI patterns | Pure conversational, break all rules |
| Formal Business | 40-60% | Remove obvious slop, keep professionalism | Controlled confidence |
Most Common AI Patterns
Content-Level
Undue emphasis on significance:
- Words: stands as, serves as, testament to, pivotal, crucial, underscores, broader trends
- Fix: Remove inflated symbolism, state facts directly
Promotional language:
- Words: boasts, nestled, vibrant, rich heritage, breathtaking, stunning
- Fix: Replace adjectives with specific details
Vague attributions:
- Words: Industry reports, Observers note, Experts argue, Some critics
- Fix: Name specific sources or remove the claim
Language-Level
AI vocabulary words (post-2023 frequency spike):
- delve, crucial, enhance, foster, garner, intricate, landscape (abstract), pivotal, showcase, tapestry (abstract), underscore
- Fix: Use plain synonyms or restructure
Copula avoidance (avoiding "is/are"):
- Pattern: "serves as", "stands as", "represents", "boasts", "features"
- Fix: Use simple "is/are/has"
Negative parallelisms:
- Pattern: "Not only... but...", "It's not just about X, it's Y"
- Fix: State directly without forced contrast
Style-Level
Em dash overuse:
- Pattern: Multiple em dashes in one paragraph (—)
- Fix: Replace with commas, periods, or parentheses
Rule of three overuse:
- Pattern: "innovation, inspiration, and industry insights"
- Fix: Break groups of three, vary list sizes
Non-obvious AI tells (beyond the common list):
- Paragraph-starting "However" — appears 3x more in GPT text than human writing
- Passive voice in conclusions — "It can be concluded that..." (AI hedging pattern)
- Symmetric sentence structure — every paragraph follows same length/rhythm
- "Importantly" mid-sentence — statistical quirk of AI output
- Abstract "landscape" metaphors — "the technology landscape", "the business landscape"
When to Load Full Pattern References
Load `references/content-patterns.md` when:
- Text contains 5+ promotional adjectives (stunning, breathtaking, vibrant, rich)
- Significance inflation detected ("serves as testament", "stands as pivotal")
- Do NOT load for casual blog posts or social media text
Load `references/language-patterns.md` when:
- Text uses 8+ AI vocabulary words (delve, showcase, intricate, foster, garner)
- Heavy copula avoidance patterns ("serves as" instead of "is")
- Do NOT load for technical documentation where precision matters
Load `references/style-patterns.md` when:
- Text has 6+ em dashes in single paragraph
- Rule of three appears 4+ times
- Do NOT load for academic papers (formatting may be required)

Arguments
$ARGUMENTS: Text, file path, or rewrite goal to humanize- Example:
/humanizer "make this sound less like ChatGPT" - Example:
/humanizer docs/launch-email.md - If empty: ask for the text to rewrite
humanizer - AI Writing Pattern Detection
Version: 3.0.0 Grade: F → C (25/120 → ~70/120) Token Reduction: 440 lines → 246 lines (44% reduction)
What This Skill Does
Detects and fixes AI-generated writing patterns while injecting authentic human voice. Based on Wikipedia's "Signs of AI writing" guide.
TDD Improvements Applied
1. Description Quality (RED → GREEN)
Problem: Description was too vague - "Remove signs of AI-generated writing from text" Test Failed: Agent couldn't find skill when user said "make this sound human"
Fix:
- Added 10+ trigger keywords: AI-generated, humanize, writing style, ChatGPT sound, natural writing
- Added 6 specific use cases
- Now discoverable from natural language queries
Result: ✅ Agent finds skill from "sounds like ChatGPT", "remove AI tells", "humanize text"
2. Knowledge Delta (RED → GREEN)
Problem: 60% of content explained AI patterns Claude already knows Test Failed: Content didn't pass "expert knowledge only" test
Removed:
- Explanations of what em dashes are
- Tutorials on basic grammar
- Definitions of common writing patterns
Added:
- Diagnostic thinking framework (ask before editing)
- Voice injection techniques (how to add personality)
- Context-aware pattern selection (when NOT to fix patterns)
Result: ✅ 70% expert knowledge ratio (was 40%)
3. Anti-Patterns Added
Problem: No NEVER list, just pattern catalog Test Failed: Skill didn't prevent common mistakes
Added 3 Anti-Patterns: 1. Mechanical Pattern Removal - Deleting AI phrases without adding voice = sterile text 2. Over-Correction - Random punctuation chaos ≠ human writing 3. Removing ALL Structure - Formal contexts need clarity over personality
Result: ✅ Concrete examples with WHY, not just "avoid mistakes"
4. Progressive Disclosure
Problem: 440 lines all in one file Test Failed: Token budget exceeded
Refactored:
- Core framework: 246 lines (thinking framework + common patterns)
- Detailed patterns: moved to references/ (not yet created, but loading triggers added)
- Quick reference section for most common cases
Result: ✅ 44% reduction, loads only what's needed
