Plumbline · OSS launch

LinkedIn carousel — 4-slide mockup

A rendered preview of the launch carousel in the ActaClad brand, so the flow and copy can be judged before it's rebuilt in Canva. Each artboard below is true 4:5 (1080×1350) — swipe order top to bottom.

01Hook— stop the scroll

Security is only half the story

Your AI agent didn't get hacked.
It fell over.

Security scanners tell you if your AI can be attacked. Plumbline tells you if it can survive production.

Gold is the single accent; the red is only finding-severity on slide 3, not brand.

Type

  • Headlines: a high-contrast display serif (Canva: Playfair Display / Fraunces) — Georgia is the on-screen stand-in here.
  • Labels & body: a rounded geometric sans (Poppins / your brand sans).
  • Scan & install: a mono (JetBrains Mono / IBM Plex Mono).

Recurring elements

  • Left connector rail with dot terminals (cream top, gold-ring bottom).
  • Faded AC hexagon, bottom-left, bleeding off-canvas.
  • ACTACLAD.COM footer on every slide.
  • One gold "highlight-box" punch word per idea (the brand "Live" treatment).

Notes

  • Export at 1080×1350 (4:5) — max feed height on LinkedIn.
  • Canonical line (slide-1 sub) — use verbatim everywhere (README, blog, HN, X, both LinkedIn posts): "Security scanners tell you if your AI can be attacked. Plumbline tells you if it can survive production." The hook stays on top of it.
  • Stats are honest: "60-rule catalog · 32 available today" — never "60 reliability rules" (four pillars; 32 shipped). The outcomes list maps only to rules that fire.
  • Slide 3 shows the real branded HTML report (`plumb scan --open`) — screenshot it at 1080px wide for crisp text.
  • Repo link goes in the first comment, not the post body (reach).
