persona_get

Read one persona of a brand: who the brand talks to, and the words that this audience uses.

Ask for work for one audience of a brand. The agent reads that persona in full.

“Write three headlines for Acme, for the Loyalists.”

The agent calls persona_get for the Loyalists of Acme. It reads the body of the persona, with its frictions and its words, together with the body of the brand. You then get headlines that answer a real objection in the words of the reader.

The job guide Describe a brand shows each step of the job.

Reference

Fetch one of a brand’s personas — an audience archetype describing who the brand talks to. Returns the full context (its body, one Markdown text) and the age range. An unwritten body is null. Echo the revision back as base_revision when updating. Personas are listed inside brand_get; there is no separate list tool.

Input

Argument	Type	Required	Description
`brand_name`	string	yes	The slug of the brand that owns the persona.
`persona_name`	string	yes	The persona slug. Unique within its brand, so it must be paired with brand_name.

Output

A successful call returns this object in structuredContent.

Field	Type	Always present	Description
`persona`	object	yes	The persona in full.
`persona.ageMax`	integer, 0 to 120 or null	yes	The highest age of the audience. `null` when the range has no upper bound.
`persona.ageMin`	integer, 0 to 120 or null	yes	The lowest age of the audience. `null` when the range has no lower bound.
`persona.body`	string or null	yes	The context of the persona, as one Markdown text. `null` when no body is written. Headings such as Profile, Motivations, Frictions and Language are the advice of the tools, and the body does not need them.
`persona.brandId`	string	yes	The brand that owns the persona (`brd_…`).
`persona.createdAt`	number	yes	Milliseconds since the Unix epoch, in UTC.
`persona.createdBy`	string	yes	The user who created the record (`usr_…`).
`persona.description`	string	yes	One line about the persona. An agent picks a persona on it.
`persona.id`	string	yes	The id of the persona (`psn_…`).
`persona.name`	string	yes	The display name.
`persona.revision`	number	yes	The version of the record. Each change adds 1. Send it as `base_revision` to update or delete the record.
`persona.slug`	string	yes	The handle of the persona. It is unique in its brand, not in the organization. The tools take it as `persona_name`.
`persona.updatedAt`	number or null	yes	Milliseconds since the Unix epoch, in UTC. `null` until the first change.

The result, in structuredContent:

    "ageMin": 28,
    "body": "## Profile\n\nRunners of 40 to 80 kilometres a week, ten years in, with one pair in rotation and one on the shelf.\n\n## Motivations\n\nThey want the same shoe again, and proof that it is the same. A resole keeps them running on a pair they trust.\n\n## Frictions\n\nThey fear the new model is worse than the one they know. A change of sole or of last reads to them as a risk, not as progress.\n\n## Language\n\nThey say \"my daily trainer\" and \"I got 900 out of the last pair\". They ask about the drop and the stack, never about the technology.",
