Write a Tagline That Earns Its Place

    You are a brand copywriter. Most taglines are decoration — they could sit under any logo in the category and nothing would change. I want one that would be wrong for a competitor to use.

**Brand:** {{brand}}
**What we do and for whom:** {{offering_and_audience}}
**Our positioning or brand platform:** {{positioning}}
**What customers say we're best at (their words):** {{customer_language}}
**Competitor taglines:** {{competitor_taglines}}
**Where this line will live** (under the logo / campaign only / homepage hero / packaging / ads): {{usage}}
**Tone:** {{tone}}

Do this:

1. **Decide what this line has to do.** Given where it lives, tell me which job it should take, and why the others are wrong here:
   - Say what we do (useful when we're unknown)
   - Say who we're for
   - Claim the benefit
   - State a belief or point of view
   - Be a memorable device that carries recognition over time

2. **Write 8 to 12 candidates across at least four different strategic angles.** Group them by angle and label each. Vary the length — include some at three words and some at eight.

3. **Stress-test every candidate** on:
   - **Swap test** — could a named competitor use this line unchanged? If yes, it's dead. Say which competitor.
   - **Say-it-out-loud test** — does it survive being spoken, or is it only readable?
   - **Truth test** — do we actually deliver this today?
   - **Longevity test** — does it still work if we expand the product line?
   - **Cliché check** — flag anything reaching for "reimagined," "made simple," "for the way you work," "beyond," "elevate," or a two-word alliteration that means nothing.

4. **Recommend three finalists**, ranked, each shown in situ: under the logo, as an ad end-line, and in a sentence of body copy. Say what each one commits us to.

5. **Tell me how to test it for real** — the cheap version (five customers, no context, ask what they think we do) and what a good answer sounds like.

Hard rules:
- Kill your own candidates in the stress test. If a candidate fails the swap test, mark it FAILED rather than defending it.
- Don't write a line that promises something my inputs don't support.
- If the honest answer is "this brand doesn't need a tagline yet," say so and explain what to do instead.
