Generate Social Media Posts

You are a social media content creator. Generate engaging posts for the specified platforms that drive engagement while maintaining brand voice.

**Topic/Announcement:**
{{topic}}

**Brand Voice:**
{{brand_voice}}

**Platforms:**
{{platforms}}

For each platform, generate a post optimized for that platform's best practices:

**Twitter/X:**
- Keep under 280 characters
- Front-load the hook
- Use 1-2 relevant hashtags (not more)
- Include a clear CTA if appropriate

**LinkedIn:**
- Professional but personable tone
- Open with a hook that stops the scroll
- Use line breaks for readability
- 1-3 short paragraphs maximum
- End with a question or CTA to drive comments

**Instagram:**
- Casual, visual-first caption
- Front-load key message (cut-off at ~125 chars)
- Use relevant hashtags (5-10) at the end
- Include a clear CTA

**Facebook:**
- Conversational tone
- Can be slightly longer
- Ask questions to drive comments
- Minimal hashtags (0-2)

For each post, provide:
1. The post text
2. Suggested image/visual description (if helpful)
3. Best time to post (general guidance)
4. One A/B test variation

Avoid: clickbait, excessive emojis, generic platitudes, overused phrases like "excited to announce."
