  Build a LinkedIn document post (carousel) - slide-by-slide copy, the cover
  that earns the swipe, and the PDF to upload. Use when the user says
  "carousel", "document post", "slides for LinkedIn", "turn this into a
  carousel", or has a list-shaped idea that would die as a text post.

li-carousel

Document posts are the highest-dwell format on LinkedIn, because a swipe is counted and a scroll is not. The format rewards one idea broken into steps. It punishes a text post cut into pieces.

When to use it instead of a text post

Use a carousel when the idea has **sequence** - steps, a countdown, a before/after progression, a framework with parts. Use a text post when the idea is one claim. Splitting one claim across eight slides is the most common way carousels fail, and if that is what the user has, say so and hand them to `/li-post`.

Structure

8-12 slides. Under 8 is a text post. Over 12 and the completion rate falls off a cliff.

1        COVER      the hook, 6 words or fewer, plus one line of promise
2        THE STAKE  why this matters, in one sentence
3-N      ONE IDEA PER SLIDE. A headline of 3-7 words, and at most 25 words
                    under it. If a slide needs a paragraph, it is two slides.
N+1      RECAP      the whole thing as a list, so the screenshot is useful
LAST     CTA        one action. Follow, comment a keyword, or the link. One.

Slide copy rules

• **Slide 1 is 80% of the result.** Six words. Big. The rest of the deck

cannot save a cover nobody swipes.

• **Number every slide** (3/10). Completion goes up when people can see the

end.

• **No slide is a paragraph.** If you cannot say it in 25 words, split it.
• **The recap slide is the one people screenshot.** Make it standalone.
• **The user's handle on every slide**, small, bottom corner. Screenshots

travel without you.

Making the PDF

LinkedIn wants a PDF, 1080x1350 (4:5) for maximum feed real estate, under 100MB, under 300 pages. Build it as HTML and print to PDF:

# one page per slide, 1080x1350, no margins
# then: Chrome headless --print-to-pdf, or any HTML-to-PDF you already use

Write the HTML with one `<section>` per slide, `width:1080px; height:1350px; page-break-after:always`, a single accent colour, and type no smaller than 28px - people read these on a phone at thumbnail size. If the user has a brand skill or design system in this project, use it and do not invent a palette.

Output

The slide-by-slide copy first, as a numbered list the user can read in ten seconds. Then the accompanying **post text** - a carousel still needs 2-3 lines above it, which is the actual hook in the feed. Run both through `/li-human`. Then build the PDF only if the user approves the copy.

Nothing is uploaded to LinkedIn. The user posts the PDF themselves.
