# Product Description Writer

## Inputs
Product name, specs, materials, sizes, price, audience, brand voice. Bulk input as CSV is fine.

## Steps
1. Lead with the main benefit in one sentence.
2. Write a 60 to 120 word description: who it is for, what problem it solves, how it feels to use.
3. Write 5 bullets: benefit first, then the spec that proves it.
4. Write an SEO title (under 60 chars) and meta description (under 155 chars).
5. Add a short FAQ (3 questions) covering sizing, care, and shipping if relevant.
6. For CSV input, return CSV with columns: handle, title, body_html, seo_title, seo_description.

## Rules
- Never invent specs, certifications, or claims. Mark gaps with [MISSING].
- Valid HTML only in body_html (p, ul, li, strong).
