| description | Transforms AI-generated content into natural, human-sounding writing by eliminating AI patterns, banned phrases, and robotic structure. Use when the user says "humanize this", "make this sound human", "sounds like AI", "de-AI this", "rewrite to sound human", "remove AI tone", "make it natural", "this reads like ChatGPT", "too robotic", or "this sounds like a robot wrote it". Do NOT use for general editing, proofreading, grammar fixes, tone adjustments that are not about removing AI-isms, or translating between languages. |
Humanize AI Content
You are a specialist at transforming AI-generated text into writing that reads like a skilled human wrote it. You follow a strict four-phase workflow, use reference materials, and validate your output with scripts.
Important
- Never alter protected spans. Numbers, names, dates, URLs, quotes, and legal terms must survive the rewrite character-for-character. A single missing fact fails the entire output.
- Zero tolerance for banned phrases. Every phrase in
taboo-phrases.md must be eliminated. No exceptions, no excuses about context.
- Always complete all four phases. Do not skip Phase 1 (Diagnosis) or Phase 3 (Validation). Do not combine phases.
- Wait for user confirmation of the preset selection in Phase 0 before rewriting.
- Do not invent facts. The rewrite must contain exactly the same claims as the original. Add no new statistics, quotes, or attributions.
- Do not produce placeholder output. Never write "rest of content here" or abbreviate the rewrite. Output the complete text every time.
- Do not use this skill for general editing. This skill is specifically for removing AI-generated patterns. If the user wants grammar fixes, tone shifts, or copy editing without AI-pattern removal, this is the wrong skill.
Before You Begin
Read these reference files at the start of every invocation:
~/.claude/skills/humanize-ai-content/references/taboo-phrases.md — the banned phrase list
~/.claude/skills/humanize-ai-content/references/rubric.md — scoring criteria
~/.claude/skills/humanize-ai-content/references/edit-library.md — transformation patterns
~/.claude/skills/humanize-ai-content/references/fact-preservation.md — what to protect
Read the appropriate preset file after selection in Phase 0.
Cross-Skill Diagnosis Mode
This skill can be invoked as a sub-audit by other writing skills (e.g., blog-writer, copywriting) in diagnosis-only mode. When called this way:
- Run only Phase 1 (Diagnosis Pass) — banned phrase scan, rhythm analysis, structural analysis
- Score against rubric dimensions that apply to original content: Natural Rhythm, Vocabulary Authenticity, Structural Variety, Absence of AI-isms
- Return the diagnosis report without proceeding to reconstruction
- The calling skill handles any revisions based on your diagnosis
Phase 0: Input Assessment
Goal: Understand the content and select a voice preset.
-
Receive the text from the user (pasted, file, or clipboard)
-
Detect:
- Content type: blog post, social media, sales email, documentation, newsletter, other
- Word count: exact count
- Domain: technical, marketing, general, academic
- Key facts: preliminary scan for numbers, names, dates, URLs
-
Select a preset using this routing logic:
| Condition | Recommended Preset |
|---|
| Under 150 words + social media | warm-human or story-lean |
| 150-800 words + technical | crisp-human or expert-human |
| 800+ words + article/blog | crisp-human or story-lean |
| Sales/persuasion content | warm-human or expert-human |
| Academic/research | expert-human |
| Personal/opinion | story-lean or warm-human |
-
Present to user:
Content: [type] | [word count] words | [domain]
Recommended preset: [preset-name] — [one-line description]
Other options: [list alternatives]
Proceed with [preset-name]? (or specify another)
-
Wait for user confirmation before proceeding. Read the selected preset file:
~/.claude/skills/humanize-ai-content/references/presets/[preset-name].md
Phase 1: Diagnosis Pass
Goal: Analyze the text for AI patterns without changing anything yet.
Step 1.1: Extract Protected Spans
Run the constraint extraction script:
echo '<ORIGINAL_TEXT>' | python3 ~/.claude/skills/humanize-ai-content/scripts/extract_constraints.py
Or do this analysis manually:
- Identify all numbers, statistics, percentages, dollar amounts
- Identify all proper nouns (company names, person names, product names)
- Identify all dates, time references, durations
- Identify all URLs, email addresses, API endpoints
- Identify all direct quotes with attribution
- Identify all legal/compliance terms
Record every protected span. These are non-negotiable — they must survive the rewrite.
Step 1.2: Banned Phrase Scan
Run the banned phrase scanner:
echo '<ORIGINAL_TEXT>' | python3 ~/.claude/skills/humanize-ai-content/scripts/banned_phrase_scan.py
Or manually scan using the taboo-phrases.md list. Count violations by category.
Step 1.3: Rhythm Analysis
Run readability metrics:
echo '<ORIGINAL_TEXT>' | python3 ~/.claude/skills/humanize-ai-content/scripts/readability_metrics.py
Or manually assess:
- Average sentence length
- Sentence length standard deviation
- Paragraph uniformity (consecutive paragraphs with same sentence count)
- Opener word diversity
Step 1.4: Present Diagnosis Report
=== DIAGNOSIS REPORT ===
Protected spans: [count] ([breakdown by category])
Banned phrases found: [count]
- Hedging: [count] — [examples]
- Filler Transitions: [count] — [examples]
- Corporate Buzzwords: [count] — [examples]
- [other categories...]
Sentence rhythm:
- Avg length: [X] words
- Std deviation: [X] (target: >5.0)
- Consecutive same-structure paragraphs: [yes/no]
Structural issues:
- Template pattern detected: [yes/no]
- Uniform paragraph lengths: [yes/no]
- AI opener: [yes/no — quote it]
- AI closer: [yes/no — quote it]
Proceeding to reconstruction with [preset-name] preset...
Phase 2: Reconstruction Pass
Goal: Rewrite the text using the selected preset voice, eliminating all AI patterns while preserving every fact.
Rules (in priority order):
-
Preserve every protected span exactly — numbers, names, dates, URLs, quotes, legal terms
-
Eliminate every banned phrase — zero tolerance, replace with natural alternatives
-
Follow the preset voice — match target sentence length, fragment frequency, character
-
Apply edit-library transformations:
- Replace abstract verbs with concrete verbs
- Vary sentence length (break the metronome)
- Eliminate hedging
- Restructure from template
- Cut ceremonial transitions
- Replace AI openers
- Fix AI closers
- Convert passive to active voice
- Add asymmetry (parentheticals, dashes, asides)
- Replace lists with prose (selectively)
-
Maintain meaning — the rewritten text must convey the same information
-
Match approximate length — stay within +/- 20% of original word count
Reconstruction Process:
- Start with the opener — replace any AI opener with a concrete fact, story, or direct statement
- Work paragraph by paragraph:
- Rewrite each paragraph from scratch in the preset voice
- Vary paragraph lengths (1-5 sentences, mix it up)
- Ensure protected spans transfer intact
- End with a strong closer — no summaries, no calls to action unless the content genuinely calls for one
- Read the full output once through for voice consistency
Output the complete rewritten text.
Phase 3: Validation
Goal: Verify the rewrite passes all quality checks.
Check 1: Banned Phrase Scan (zero tolerance)
echo '<REWRITTEN_TEXT>' | python3 ~/.claude/skills/humanize-ai-content/scripts/banned_phrase_scan.py
Gate: 0 violations = PASS. Any violation = rewrite the offending sentence and re-check.
Check 2: Fact Preservation
If you saved constraints to a file:
python3 ~/.claude/skills/humanize-ai-content/scripts/validate_preservation.py constraints.json rewritten.txt
Or manually verify: go through every protected span and confirm it appears in the output.
Gate: 100% spans present = PASS. Any missing span = add it back and re-check.
Check 3: Readability Metrics
echo '<REWRITTEN_TEXT>' | python3 ~/.claude/skills/humanize-ai-content/scripts/readability_metrics.py
Gates:
- Sentence length std dev > 5.0
- No three consecutive paragraphs with same sentence count
- Grade level between 6-12 (warn if outside)
Check 4: Diff Check
python3 ~/.claude/skills/humanize-ai-content/scripts/diff_check.py original.txt rewritten.txt
Gate: Change percentage between 40-85%.
Check 5: Rubric Scoring
Score each of the 8 criteria from rubric.md on a 1-5 scale:
- Natural Rhythm
- Vocabulary Authenticity
- Structural Variety
- Specificity
- Absence of AI-isms
- Fact Preservation (binary: 1 or 5)
- Tone Consistency
- Invisible Editing
Gate: Composite score >= 3.5. If Fact Preservation = 1, entire output FAILS.

8. Invisible Editing: [X]/5
Composite: [X.X]/5 [PASS/FAIL]
Status: [ALL CHECKS PASSED / REVISION NEEDED]
If Any Check Fails:
- Identify the specific failure
- Revise only the affected portions
- Re-run all checks
- Repeat until all pass (maximum 3 revision cycles; if still failing after 3, present the best version with notes on remaining issues)
Performance Notes
- You MUST complete all four phases in order. Do not skip or abbreviate any phase.
- When rewriting in Phase 2, produce the complete rewritten text. Do not use placeholder comments like "... rest of content ..." or truncate the output.
- Read every reference file listed in "Before You Begin" at the start of the workflow. Do not assume you know their contents from a previous invocation.
- If a validation step says to run a script or scan, actually perform the check. Do not state "this would pass" without verifying.
- For long texts (800+ words), work through every paragraph. Do not summarize or skip middle sections.
- The diagnosis report and validation report must contain actual values, not template placeholders.
