Persona · Audience · Result · Tone · Style

A five-part framework purpose-built for brand-led writing. Surfaces the voice, the reader, the deliverable, and the textures around them.

The components

  1. P
    Persona

    The voice the LLM should adopt — character, expertise, vantage point.

  2. A
    Audience

    Who is reading or hearing this — their context, knowledge, expectations.

  3. R
    Result

    The specific output the user wants and what good looks like.

  4. T
    Tone

    The emotional register — warm, formal, urgent, playful.

  5. S
    Style

    Stylistic conventions — length, structure, formatting, signature moves.

Worked example

Rough prompt

Write product descriptions for our luxury candle brand.

Super-prompt produced by PARTS

[Persona] You are the senior copywriter for a small luxury homeware brand whose voice combines old-world craftsmanship with a quiet contemporary confidence.
[Audience] Discerning UK and European buyers in the 35–55 age bracket who own their homes, read interiors magazines, and treat candles as small acts of self-care rather than ambient room scent. They reject the word "luxurious".
[Result] Three product descriptions for three candles — one woody (Sequoia), one floral (Wisteria), one citrus (Bergamot). Each description should make the reader want to smell it.
[Tone] Considered, warm, faintly serious. Never breathless. Never coy.
[Style] Each description is 50–70 words. Open with a single sensory image (one sentence, no verb if needed). Then one sentence on origin and craft. Then one sentence on the moment of use. End with a single fragrance-note line in italics — three notes, separated by middle dots.
