Structural Humanizer

structural-humanizer

Read this first. The humanizer skill fixes words: "delve", em dashes, rule of three,

negative parallelism. This skill fixes what survives that pass: the structure. The two

are different jobs, run in sequence. Surface pass first, structural pass second.

Why this layer matters more. StoryScope (Russell et al. 2026, arXiv:2604.03136)

classified 61,608 stories from humans and 5 LLMs using only discourse-level features,

with all style features withheld: 93.2% detection accuracy. Then they ran AI text

through LAMP, a professional span-level rewriting framework that removes cliche,

purple prose, and redundant exposition (functionally, a surface humanizer). Detection

dropped 1.6 points. Meanwhile the surface layer is decaying on its own: GPT 5.4

already slashed em-dash usage, and fine-tuning drops stylistic detection from 97% to

3%. The durable fingerprint is structural, and fixing it requires structural rewrites,

not word swaps. Full findings with numbers: references/storyscope-findings.md.

The trap (same trap as unslop-ui)

Do not replace one default with another. If every piece now opens mid-scene, names

three feelings, and ends unresolved, that is a new detectable cluster. The study's

deepest finding is convergence: all five AI models occupy one tight region of

structural space while humans are dispersed and rare. Rarity IS the human signal.

So: **pick 1-2 structural interventions per piece, vary them across pieces, and be

able to say why this piece got this shape.** Never apply the whole menu at once.

The six audits

Run these one at a time (aspect-based checking found 95% of issues in the study's own

pipeline vs 68% for one mega-pass). Numbers are human vs AI rates from the study.

1. Theme explicitness (the biggest tell)

AI states its lesson. Narrator explains the theme 77% of the time vs 52% for humans;

themes are moralized ~20% harder; everything ties back to one central point.

In content: the takeaway sentence, "What this means for you", the thesis restated at

every section end, every example dutifully interpreted.

Fix: state the point once, where it lands hardest. Cut every restatement. Let at

least one example sit uninterpreted. Trust the reader.

2. Structural tidiness

AI writes single-track: unbroken causal chain, no subplots (79% vs 57%), everything

resolved, protagonist-choice endings. Humans digress, loop, and leave threads open

(thematically parallel tangents: 42% vs 21%; ambivalent endings far more common).

Fix options: one tangent that only obliquely relates; one question raised and

explicitly not answered; stop before the resolution.

3. Emotion mode (inverts "show don't tell")

The single largest gap in the study: AI performs emotion through the body and

atmosphere 81% of the time vs 38% for humans ("chest tightened", "breath caught",

"the lamplight dimmed"). Humans just name it: explicit emotion labels 29% vs 8%.

Fix: say the feeling plainly ("honestly, it scared me", "I was pissed"). Reserve

embodied detail for the one moment that earns it. Yes, this contradicts classic

writing advice. Classic writing advice is now a machine signature.

4. Reference specificity

Humans name real things: specific texts, people, brands, places, prices (explicit

named references 47% vs 24%). AI stays at vague allusion (72% vs 50%) and avoids

naming real brands or works.

Fix: "a popular productivity book" becomes "Deep Work". "An expert" gets a name.

"Recently" gets a date. Add the price, the version number, the city.

5. Reader engagement

Humans acknowledge the reader (direct address 28% vs 7%; fourth-wall permeability 67%

vs 39%). "AI writes as though no one is watching." Content marketing already uses

"you" constantly, so the transferable move is acknowledging the writing itself:

"I know how this sounds", "skip this section if you already run ads", "you're

probably skimming, so here's the number". Use sparingly; it is a spice.

6. Shape convergence

Does this piece have the same skeleton as your last three? Same opener type, same

arc, same closer? That is the cluster forming. Compare against recent pieces and

break the pattern before publishing.

Workflow

• Extract the skeleton first. Outline the piece: beats in order, where the

lesson is stated (and how many times), time structure (linear or not), what gets

resolved, tangent count, emotion moments and their mode, named vs vague

references. Audit the outline, not the prose. (This is the study's own method:

structural tells hide from prose-level reading.)

• Run the six audits against the skeleton, one at a time.
• Choose 1-2 interventions from the menu below. Deliberate, genre-appropriate

(see references/genre-calibration.md), different

from the last piece.

• Rewrite structurally. Move sections, cut codas, delete restatements. Do not

just polish sentences; that is the other skill's job.

• Scan: python3 scripts/structural_scan.py <file> catches the pattern-matchable

slice (embodied-emotion cliches, takeaway markers, vague allusions, uniformity).

• Re-check for the trap. If the fix looks like the fix you applied yesterday,

vary it.

Intervention menu (rotate, never all at once)

• Outcome first. Open at the end state, then rewind. Payoff lands mid-piece, not

in the close.

• Cold open mid-scene. Start inside the story, loop back for context later.
• Delayed reveal. Withhold the number/name/result the piece is built on until

two-thirds through.

• Recontextualization callback. Make an earlier detail mean something new:

"Remember the $80/month from the top? That was the cheap part."

• The oblique tangent. One paragraph that parallels the theme without serving it.

Do not tie it back explicitly.

• The open thread. Name a question you cannot answer yet and leave it standing.
• Genuine ambivalence. End with both feelings intact instead of a resolved lesson.
• The named thing. Swap every vague allusion for a real, checkable specific.
• Plain emotion. Replace body-performance with the stated feeling.
• Acknowledged reader. One moment that admits someone is reading this.
• End hot. Stop at the spike instead of the quiet coda (see Claude fingerprint).

Model fingerprints (know what drafted the text)

Most drafts here come from Claude, whose fingerprint is the most distinctive of all

five models. If the draft is Claude: flat event escalation (uniform intensity

throughout; fix by varying stakes and energy across the piece), the epilogue habit

(a wrap-up coda after the natural ending; cut it and end earlier), **reverent, quiet

endings** (occasionally end on the spike or unresolved). GPT drafts over-index on

distant retrospective framing ("years later, I realize") and social/gossip mechanics.

Gemini produces the tidiest endings; kill the bow on top.

What this skill does not do

It does not fix vocabulary or punctuation (run humanizer). It does not impose a

voice (that is jens-blog-writer / solo-scale-writer / the Nick Saraev templates).

It does not make text undetectable; nothing does. And one honest caveat: StoryScope

studied ~5,000-word fiction. The transfer to short nonfiction is an inference, but the

core pattern (over-explanation, tidiness, linearity, convergence to one default shape)

is exactly what independent analyses of nonfiction AI slop keep finding, and the

short-text subset that transfers cleanly is audits 1, 3, 4, and 6.
