description: Use when the user wants to define their ideal customer or build review personas — "build our ICP," "create a buyer persona," "who is our target customer," or "make personas to pressure-test this content." Produces structured, reusable personas with a review lens so they can also be used to critique drafts from a real buyer's point of view.

# ICP & Persona Builder

You turn what the user knows about their market into sharp, usable personas.
Good personas are specific enough to make decisions with and double as a lens
for reviewing content. Vague demographics ("marketers, 25–45") are useless;
contexts, constraints, and pains are everything.

## Inputs (ask if missing)

- What the product does and the problem it solves.
- Who buys/uses it today (even rough notes).
- Industry/vertical, company stage and size if B2B.
- Anything known about what makes them say yes or no.

If the user has analytics, win/loss notes, or sales-call themes, use them.

## Output: one profile per persona

```
## [Name] — [Role / title]

**Background** (2–3 sentences)
How long in role, career path, team/reporting structure, company context.

**Daily reality** (3–4 sentences)
What they actually do, who they work with, what they're measured on, what
success looks like.

**Pain points** (4–5 specific bullets)
- What keeps them up at night
- Resource constraints (time, budget, authority, headcount)
- Competing priorities and internal tensions
- The gap between what's expected and what's possible

**What they need from us** (2–3 sentences)
What makes our content/product useful vs. ignorable to THIS person.

**Buying lens**
- Trigger that starts a search
- What they evaluate on
- What they're skeptical about
- Who else is in the decision

**Review lens** (for pressure-testing content)
The questions this persona asks when reading our content, and what would make
them bounce.
```

## Using personas to review content

When asked, have each persona read a draft and react in their own voice:
- What lands, what they'd skip, what they don't believe.
- The objection they'd raise.
- One thing that would make it more useful to them.

This is synthetic feedback — fast and useful for finding blind spots, but it
does not replace talking to real customers. Say so.

## Rules

- Make each persona feel like a real person with a context, not a demographic
  bucket.
- 2–4 personas max for most products; more dilutes focus.
- Distinguish buyer from user from influencer if they differ.
- Don't fabricate market facts; flag assumptions for the user to verify.

## Output

Return the persona profiles as clean markdown the user can save and reuse.
