Spanish copy reviewer (skill)

# Spanish copy reviewer

Use this skill when the user asks to review, polish or improve a marketing text in Spanish (ads, emails, landing pages, posts).

## What to do
1. Fix spelling, accents and grammar (neutral Latin American Spanish).
2. Shorten: remove filler, corporate-speak and empty phrases.
3. Raise clarity: one idea per sentence, active voice, strong verbs.
4. Keep the intent and the brand tone; don't invent facts.
5. NEVER use long dashes; use commas, periods or parentheses.

## Output
Return the corrected text first, and below it a short list of the key changes (what and why). If the text is already good, say so and only suggest optional improvements.
