Write — LinkedIn

Turn the locked master content for $ARGUMENTS into a LinkedIn carousel and caption. LinkedIn is the visual channel — the carousel is the content, posted as a PDF document, and a design tool polishes it afterward, so deliver clean slide-by-slide text plus a short design note.

Preconditions & change protocol (read first)

• Content first. Only render once the master content is locked and the person has approved it (Phase 1 / explore). If it isn't, stop and finalize the content first.
• One spine, faithful rendering. This is the same thesis as the Substack essay and Medium article, rendered for LinkedIn — it reinforces, never duplicates. Never reuse the Substack prose as slides.
• Same running example as every other asset.
• Change protocol. If the person asks to change the substance after this exists, don't patch it here — update the master content (explore), re-approve, and regenerate all platform assets (refine runs the re-sync).
• Match the person's voice — preserve their phrasing and any strong line they already wrote.

Save the output as a Markdown file so it can go straight to a design tool. The slides themselves get exported as a PDF for the LinkedIn document post — the LinkedIn portion of the design-brief artifact specifies that PDF slide-by-slide.

The carousel (≈8–11 slides)

Uploaded as a PDF "document" post.

1. Hook — one sharp claim that opens a question, plus "→" to pull the swipe. Tease the payoff; don't spoil it. Avoid any framing that contradicts the thesis.
2. Build slides — one idea each, walking the argument; give each a bold lead-in label so the deck scans at a glance.
3. Insight slide — name the non-obvious through-line ("the aha").
4. Turn / payoff — the boldest or most surprising step, framed as the natural culmination; visually distinct from the build slides.
5. Mental-model slide — a single quotable line (the slide people screenshot).
6. Where it goes — the forward-looking implication.
7. CTA — a short prompt plus an open question ("What rung are you building on?").

Keep slides to a few short lines; they must be readable on a phone.

Design note to include for the design tool: slide count; one accent color reserved for the hero element of the story; consistent neutrals elsewhere; build slides share a motif; the turn slide breaks that rhythm. If the framing is positive/evolutionary, explicitly say "no warning aesthetics (red, cracks, alert icons)." For the full slide-by-slide PDF spec, use the design-brief skill.

The caption

The text above the carousel:

• Hook line consistent with slide 1.
• 2–4 short prose paragraphs expanding the arc (single-sentence paragraphs and line breaks read well in-feed).
• "Swipe through 👇" to point at the deck.
• CTA to the long-form ("Full essay on Substack — link in the comments") and an open question to invite replies.
• 4–5 specific hashtags, no stuffing.

Caption hygiene (this is where reach is won or lost)

• External links suppress reach in the post body. Put the link in the first comment and say "link in the comments." Post the carousel, then immediately add the comment.
• A framed first comment beats a bare URL — one line that sells the click ("Wrote the long version here, where I get into [the spicy implication] 👇").
• Strip tracking params (?utm_..., ?r=..., share flags) from any shared link.

For when to post and the cross-posting funnel, hand off to the distribute skill.
