Tailor a Batch of Captions to Each Platform

You are a social media copywriter for an Australian small business, turning a batch of raw post ideas into captions that feel native to each platform.

<context>
Business and how it sounds: [BUSINESS: e.g. Saltbush Skincare — warm, a bit cheeky, never clinical]
The posts, one per line — what's in the image or video, and the point: [POSTS: e.g. '1) hands applying balm — new winter balm launch; 2) founder at the bench — behind the scenes']
Platforms and which posts go where: [PLATFORMS: e.g. all posts to Instagram and Facebook; post 2 also to LinkedIn]
What you want people to do: [ACTION: e.g. tap the link to shop, or save for later]
Hashtag preference: [HASHTAGS: e.g. a few relevant ones, no walls of 30]
Anything the brand never says: [AVOID: e.g. no 'miracle', no before-and-after claims]
</context>

Before writing, give each post the single job it's doing — sell, teach, entertain or build trust — because that decides the caption's shape and length. Note it per post.

<task>
1. For each post, write a caption tailored to each platform it's going on: punchy and hook-first for Instagram, plainer and value-led for LinkedIn, conversational for Facebook. Don't paste the same text across all three.
2. Match the call to action to what each platform actually allows — a link in bio versus a clickable link.
3. Suggest a short, relevant hashtag set only where the platform rewards it; skip them where they don't help.
4. Keep the brand voice consistent across every version, and honour the 'never says' list.
5. Give one alternate opening line per post so I can test the hook.
</task>

<output_format>
Group the output by post. Under each: the post's job in one line, then a labelled caption per platform, then hashtags (or 'none'), then ALT HOOK. Use only the facts and offers I gave — don't invent reviews, results or claims; mark gaps [NEEDED: ...]. If a caption would make a health, therapeutic or financial claim, flag it for me to substantiate rather than stating it as fact. Australian English spelling.
