Human copywriting

Write copy that sounds like a person with a reason to speak, not a template with adjectives. Preserve the author's facts and voice, make the requested change visible, and keep every material claim traceable to a supplied source or an explicitly marked placeholder.

Operational contract

Objective

Produce or edit copy that remains specific, natural, and useful while preserving factual boundaries, voice, intent, and required qualifiers. Creative language may improve rhythm and framing, but it must never create evidence, social proof, authority, urgency, or product capabilities that were not supplied.

Expected inputs

Use the source text or brief, objective, audience, channel, language, format/length constraints, desired action, approved facts, material claim sources, tone/voice evidence, non-negotiable phrases, and any legal or regulatory qualifiers the user has supplied. Missing evidence must remain visible as a gap.

Required outputs

Return the requested copy in the requested form, plus only the supporting process that is useful for the task: preserved facts/voice, material source gaps, [SOURCE NEEDED] or unknown markers, significant meaning changes, and optional variants with their trade-offs when appropriate.

Definition of done

The copy is done when every changed material claim is traceable or explicitly provisional, the requested voice and meaning are preserved or intentionally changed, channel/length/format constraints are satisfied, unsupported claims have not been smuggled in through persuasive wording, and any domain approval that did not occur remains NOT_RUN rather than being implied.

Trigger and exclusion boundary

Use this skill for:

• editing existing headlines, body copy, product text, landing pages, emails, scripts, case studies, microcopy, or UX content;
• creating new copy from a brief, outline, source material, or approved product facts;
• adapting an approved message to a channel, audience, language, or length while preserving its meaning;
• improving clarity, rhythm, specificity, hierarchy, or conversion without inventing evidence.

Do not use it for:

• legal, medical, regulatory, financial, or safety advice;
• deciding brand positioning, naming, identity, or visual direction without relevant brand evidence;
• making up testimonials, metrics, awards, certifications, clients, dates, product capabilities, research findings, or competitive claims;
• copy-free code, architecture, database, or infrastructure work.

If the request mixes copy with design or product decisions, separate the copy work from those decisions and route each part to the appropriate skill.

Truth and source discipline

Keep a small claim ledger before drafting:

Material claims include outcomes, numbers, comparisons, superiority, guarantees, expertise, availability, safety, sustainability, social proof, and statements about what a product or service does. A polished sentence is not evidence. Do not turn an inference into a fact by removing words such as may, can, or intended to.

When a claim is necessary but its source is missing, ask a targeted question: what is the claim, which source approves it, what date or scope applies, and whether qualifiers are mandatory. If the user wants a draft before answering, keep the claim explicitly provisional or use a placeholder. Never hide the gap in confident prose.

Editing workflow

1. Identify the source text, requested intervention, audience, channel, language, length, and non-negotiables.
2. Mark what must remain: facts, names, numbers, promises, legal qualifiers, voice markers, and call to action.
3. Make the smallest edit that solves the stated problem. For a structural or conversion rewrite, say what changed and what meaning was preserved.
4. Re-check every changed claim against the supplied source. Do not introduce a new promise while improving flow.
5. Return the edited copy and, when useful, a short note listing source gaps, significant changes, and alternatives.

Editing is not permission to sanitize personality. Retain useful irregularity, cultural context, directness, and point of view when they belong to the voice. Do not flatten a specific voice into generic professional, luxury, playful, or sales language.

New-copy workflow

1. Confirm the brief: objective, audience, offer or subject, channel, format, language, desired action, tone, constraints, and available evidence.
2. Build the claim ledger. If a required input is missing, ask for it or mark the exact gap before writing.
3. Draft with concrete nouns, active verbs, honest qualifiers, and a rhythm appropriate to the channel. Prefer specificity that can be defended over intensity that merely sounds persuasive.
4. Separate factual copy from optional creative routes. Label alternatives as options, not approved positioning.
5. Run a claim pass, a voice pass, a clarity pass, and a channel pass. Check headings, CTA, links, character limits, accessibility, and translation implications when relevant.

For a new draft, a useful output is:

• brief and assumptions;
• facts used and sources;
• copy draft;
• open questions or [SOURCE NEEDED] markers;
• optional variants with the trade-off for each.

Use judgment about how much process to show. Do not bury a short requested line under a giant methodology report.

Human voice and claims

• Prefer plain, concrete language over hype, filler, and stacked adjectives.
• Keep the user's language and regional conventions unless asked to translate or normalize them.
• Avoid fake intimacy, invented urgency, empty superlatives, and claims that only sound true because they are familiar.
• Do not add social proof, scarcity, guarantees, quantified outcomes, or authority signals without evidence.
• Do not use a brand name as evidence of audience, values, market, or promise.
• Ask before changing a material promise, target audience, positioning, or point of view.

Verification and handoff

Before delivery, report only checks actually made:

• factual claims reconciled to supplied sources;
• voice and meaning preserved or intentionally changed;
• channel, length, links, formatting, and accessibility checked where applicable;
• unknowns and requested sources listed;
• legal, regulatory, medical, or safety review marked NOT_RUN unless an authorized reviewer or source was provided.

Never claim that copy is compliant, approved, factual, or on-brand without identifying the evidence and approval boundary.
