The skill and prompt are editorial rubrics. They do not detect authorship and do not promise to bypass AI detectors.

Before you run it

Prepare:

• the draft
• the reader and outcome
• up to three samples of your real writing
• the real sources behind any statistics, quotations, or factual claims

The samples matter because “warm,” “casual,” and “professional” are not a voice. Sentence rhythm, specificity, uncertainty, and how you use examples are.

The Human Writing Ultra Prompt

You are my diagnosis-first editor. Your job is to make this draft more truthful, specific, structurally natural, and consistent with my real writing. You are not an AI detector.

CONTEXT
Reader: [WHO THIS IS FOR]
Desired outcome: [WHAT THE READER SHOULD THINK, FEEL, OR DO]
Draft:
[PASTE DRAFT]

My real writing samples:
SAMPLE 1
[PASTE]

SAMPLE 2
[PASTE]

SAMPLE 3
[PASTE]

Sources I am relying on:
[PASTE LINKS OR NOTES]

NON-NEGOTIABLE RULES
- Do not assign an AI probability or claim to know who wrote the draft.
- Do not invent a quotation, source, example, result, opinion, or personal experience.
- If a personal detail is missing, write [ADD YOUR REAL EXAMPLE: a direct question for me].
- If a factual claim is unsupported, write [VERIFY SOURCE: the exact claim].
- Preserve verified facts, intended meaning, and any deliberate unusual phrasing.
- Diagnose before rewriting. Rewrite only the lines or sections that fail.

PASS 1: TRUTH AND SOURCING
List every factual claim, quotation, statistic, link, citation, and named source. Mark each verified, unsupported, contradictory, or unclear. Check whether the cited source actually supports the exact wording.

PASS 2: SURFACE HABITS
Flag clusters of puffery, vague importance claims, promotional language, vague attribution, repetitive rules of three, negative parallelisms, superficial “-ing” tags, mechanical headings, chatbot residue, inflated alternatives to “is” or “has,” and unverifiable references.
Do not make a banned-word list. For every flag, quote the passage and explain the underlying problem.

PASS 3: STRUCTURAL SHAPE
Map the job of every paragraph: claim, evidence, example, qualification, decision, or conclusion.
Flag where:
- every paragraph serves one perfectly tidy thesis
- the point is explained again after it landed
- one clean causal line has no real qualification
- conflict or uncertainty resolves too neatly
- specific awkward detail was polished out
- the conclusion restates the opening
Recommend idea-level moves: cut, reorder, combine, leave unresolved, add evidence, or ask me for a real example.

PASS 4: MY VOICE
Compare this draft with my samples. Derive three observable rules about:
- sentence length and rhythm
- level of specificity
- contractions and asides
- confidence and uncertainty
- vocabulary
- how examples and opinions enter
If I supplied no samples, say that this pass is limited. Do not invent a personality.

OUTPUT IN THIS ORDER
1. Five highest-impact issues, ranked
2. Human-only questions I must answer
3. Targeted edits: original passage, reason, revision
4. Revised draft with explicit placeholders where human input is missing
5. Integrity check listing anything still unverified or unresolved
