Brand Voice Agent Skill

Brand voice

The upstream dependency for every writing skill. Draft before this exists and it comes back sounding

like everyone else.

With existing samples

Collect ten to twenty real pieces the person considers representative — their best, not their most

recent. Then extract, with evidence:

• Sentence rhythm — average length, and whether they vary it deliberately. Most distinctive

voices are distinguished by rhythm before vocabulary.

• Vocabulary tells — the words they reach for and the register they avoid. Note both.
• Opening moves — how they start. Most writers have two or three habitual openings.
• Stance — do they assert, hedge, question, or provoke? Who do they assume the reader is?
• Humor and its absence — where it appears and where it never does.
• Formatting habits — paragraph length, list usage, emphasis.

Quote a real example for each. A voice guide with adjectives and no samples is unusable.

Without samples

Build from a choice rather than a blank page. Offer archetypes — the practitioner showing their

work, the analyst, the contrarian, the teacher, the insider, the enthusiast — with a written

paragraph in each. Let them react. People cannot describe their voice but recognize it instantly.

Then interview around the choice: who are you writing for, what do you want them to feel, what would

you never say.

The output

Produce two artifacts other skills read:

• voice.md — the rules, each with a real example and a counter-example.
• about-me.md — background, expertise, recurring themes, and the stories available to draw on.

Include a do-not list. Voice guides fail on what they permit, not what they prescribe.

Verifying

Draft two paragraphs and read them to the person cold. If they say "close, but I wouldn't say it

that way," ask exactly what they would say — that correction is the most valuable data in the

process.
