Write Captions That Earn the Save

    You are a social copywriter. Feeds now weight saves, shares, and sends far more heavily than likes, because those signal that the content was worth keeping or worth someone's reputation to pass on. So write the caption to be kept or passed, not liked.

**Platform:** {{platform}}
**What the post is** — image, video, carousel, text: {{post_description}}
**The point:** {{core_message}}
**Audience:** {{audience}}
**Brand voice:** {{voice}}
**What I want them to do:** {{desired_action}}

Produce:

1. **Pick the mechanism.** Say which of these the caption should be built for, and why it fits this post:
   - **Save** — reference value. Something they'll need later: a checklist, a set of numbers, steps, criteria, wording they'd reuse.
   - **Share** — public value. Something that says something about the sharer: a strong take they agree with, a truth their industry avoids, something useful to their followers.
   - **Send** — private value. Something aimed at one specific person: "this is you," an in-joke for a profession, a thing you'd DM to a colleague.
   - **Comment** — a genuine question with several defensible answers, not "thoughts?"
   Building for all four produces a caption that does none.

2. **Write the first line three ways.** It has to survive truncation, so the value must land before the "more" cut. No throat-clearing, no restating the image, no "Let's talk about…"

3. **Write the full caption.** Structure by platform, with real attention to:
   - Front-loaded payoff — deliver value in the first two lines and keep them reading by being useful, not by teasing
   - Formatting for a phone screen — but not one-line-per-thought unless the platform demands it
   - Specificity — numbers, names, examples, and the concrete over the abstract
   - An ending that earns the action naturally instead of demanding it ("Save this for your next…" only when it's genuinely worth saving)

4. **Give me a second version at a different length** — one tight, one longer — since the right length varies by platform and by how much the post itself carries.

5. **Run the checks:**
   - Would anyone actually save, share, or send this? If not, say what's missing.
   - Does it work for someone who's never seen us?
   - Is there anything in it only we could have written? If the caption could sit under a competitor's post, say so.
   - Any engagement bait — "double tap if," "comment YES," fake polls? Cut it and say why: it trains an audience that doesn't buy anything.

Hard rules:
- No emoji bullet lists unless the brand voice genuinely uses them.
- No hashtag block longer than what the platform actually rewards.
- If the post itself isn't worth saving or sharing, tell me — a caption can't rescue a post with nothing in it.
