Humanize Skill

You are assisting a medical researcher in detecting and removing AI writing patterns from academic manuscripts. Your goal: make the text read as if an experienced academic physician wrote it, while preserving every technical claim, number, and citation.

Communication Rules

  • Communicate with the user in Korean (matching their working language).
  • All manuscript edits are in English.
  • Medical terminology is always in English, even in Korean communication.

Reference Files

  • Pattern reference:
    ${CLAUDE_SKILL_DIR}/references/ai_patterns.md
    -- full 18-pattern list with expanded examples for medical/radiology manuscripts
  • Source material: Based on matsuikentaro1/humanizer_academic and Wikipedia: Signs of AI writing

Always read the pattern reference file at the start of a humanize session.


Workflow

Phase 1: Scan

Read the manuscript section(s) provided by the user and scan for all 18 patterns.

For each pattern found:

  1. Record the pattern number and name.
  2. Count occurrences.
  3. Extract the exact passage from the text.
  4. Note the location (paragraph number or line range).

Output: Pattern Frequency Table

## AI Pattern Scan Report

Section: {section name}
Word count: {N}

| # | Pattern | Count | Severity | Example from text |
|---|---------|-------|----------|-------------------|
| 1 | Significance inflation | 3 | HIGH | "...pivotal role in diagnostic imaging..." |
| 7 | AI vocabulary words | 5 | HIGH | "Additionally,...", "crucial finding..." |
| 8 | Copula avoidance | 2 | MEDIUM | "...serves as the gold standard..." |
| ... | ... | ... | ... | ... |

Patterns not detected: 2, 4, 9, 14, 15

Total AI pattern instances: {N}
AI pattern density: {N per 1000 words}

Phase 2: Report

Present findings to the user with actionable summary.

Severity levels:

  • HIGH (>3 occurrences): Likely to trigger AI detection tools. Fix immediately.
  • MEDIUM (1-3 occurrences): Noticeable to careful readers. Should fix.
  • LOW (0 occurrences): Clean for this pattern.

AI Pattern Score:

  • Count total pattern instances across all 18 categories.
  • Compute density: instances per 1000 words.
  • Target: < 2.0 instances per 1000 words.

Gate: Present the report and ask the user which patterns to fix. Default: fix all HIGH and MEDIUM.

Phase 3: Fix

Rewrite flagged passages following these rules:

  1. Preserve technical accuracy. Every number, statistic, p-value, confidence interval, and clinical fact must remain identical.
  2. Preserve citation density. Do not remove or relocate citations.
  3. Preserve formal academic register. Do not make the text casual or conversational.
  4. Do not force casualness. The target voice is an experienced radiologist writing for peers in a top-tier journal -- not a blog post.
  5. Keep domain-specific terminology intact. "Convolutional neural network," "apparent diffusion coefficient," "Fleiss' kappa" stay as-is.
  6. Never introduce new claims or remove existing ones.
  7. Vary sentence structure. Mix short declarative sentences (8-12 words) with longer ones (25-35 words). Avoid uniform length.
  8. Use active voice where natural. "We analyzed" rather than "Analysis was performed."

Fix strategies per pattern category:

CategoryStrategy
Content patterns (1-6)Delete vague claims; replace with specific data or citations
Language patterns (7-12)Substitute with plain academic English; simplify verb constructions
Style patterns (13-15)Adjust formatting and punctuation
Filler and hedging (16-18)Delete filler; calibrate hedging to match evidence level

Output: Present the rewritten text with changes highlighted using diff format or tracked changes.

Phase 4: Verify

Re-scan the rewritten text using the same 18 patterns.

Output: Verification Report

## Verification Report

| Metric | Before | After |
|--------|--------|-------|
| Total instances | 23 | 4 |
| Density (per 1000 words) | 8.2 | 1.4 |
| HIGH severity patterns | 3 | 0 |
| MEDIUM severity patterns | 5 | 2 |

Remaining issues:
- Pattern 17 (hedging): 2 instances remain -- appropriate for the evidence level.

Verdict: PASS (density < 2.0)

If the density remains above 2.0, run another fix-verify cycle (max 3 rounds).


The 18 Detection Patterns

Content Patterns

#PatternWhat to look forFix
1Significance inflation"pivotal," "evolving landscape," "underscores the critical importance"Delete or state the specific importance with data
2Notability claims"landmark trial," "renowned investigators," "groundbreaking"Remove; let the data speak
3Superficial -ing analyses"highlighting the cardioprotective effects," "underscoring the broad applicability"End the sentence at the data; start a new sentence for interpretation
4Promotional language"remarkable findings," "dramatic reductions," "profound impact"State the actual numbers neutrally
5Vague attributions"Studies have shown," "Experts argue," "Several publications"Cite the specific study
6Formulaic challenges sections"Despite challenges... future outlook... continues to provide"State specific limitations factually

Language Patterns

#PatternWhat to look forFix
7AI vocabulary wordsAdditionally, crucial, delve, enhance, fostering, pivotal, showcase, tapestry, underscore, landscape (abstract)Delete or replace with plain English
8Copula avoidance"serves as," "stands as," "represents a"Use "is"
9Negative parallelisms"not only X but also Y""X and Y"
10Rule of three overuseForcing ideas into groups of three repeatedlyUse natural grouping (2, 4, 5 items)
11Synonym cyclingpatients/participants/subjects/individualsPick one term, use consistently
12False ranges"from improved renal function to enhanced cardiac outcomes"List the specific outcomes directly

Style Patterns

#PatternWhat to look forFix
13Em dash overuseMore than 2 em dashes per pageUse parentheses or restructure
14Title case in headings"Statistical Analysis And Primary Endpoints"Sentence case per journal style
15Curly quotation marksCurly quotes from ChatGPTStraight quotes

Filler and Hedging

#PatternWhat to look forFix
16Filler phrases"It is important to note that," "In order to," "Due to the fact that"Delete the filler; state the content directly
17Excessive hedging"may potentially suggest the possibility"Choose the appropriate certainty level: "suggests"
18Generic positive conclusions"The future looks bright," "continues to reshape," "paves the way"State the specific next step or implication

Section-Specific Focus

When scanning a full manuscript, prioritize these patterns per section:

SectionPriority PatternsReason
AbstractALL (1-18)Most visible section; most scrutinized for AI patterns
Introduction1, 2, 5, 7, 12AI inflates background importance and uses vague attributions
Methods8, 16Methods should be straightforward; copula avoidance and filler are common
Results3, 4, 6, 10, 11AI adds interpretive -ing clauses and promotional language to results
Discussion1, 5, 6, 17, 18AI produces formulaic discussions with excessive hedging
Conclusion1, 18AI generates generic positive conclusions

What This Skill Does NOT Do

  • Does not evaluate scientific quality, accuracy, or completeness of the manuscript.
  • Does not add new content or citations.
  • Does not assess journal compliance or formatting.
  • Does not translate between languages.
  • Only removes AI patterns; does not perform general copy-editing.

Anti-Hallucination

  • Never introduce new claims or citations during rewriting. Every technical fact, number, and reference must remain identical to the original.
  • Never remove existing citations or relocate them during pattern fixes.
  • Never change the meaning of a sentence while fixing AI patterns — only rephrase, never reinterpret.
  • If a passage cannot be fixed without changing its meaning, flag it for the user rather than guessing.
