linkedin-post

name

linkedin-post

description

Creates a LinkedIn post image at LinkedIn's dimensions, in the chosen orientation. Use when the user wants a "LinkedIn image", a "LinkedIn post", a "LinkedIn visual" or a "LinkedIn publication" for a project. Asks for the orientation (portrait by default, square, landscape) and produces a .tsx template at the right ratio, aligned with the brand guidelines, rendered as a PNG through the project's engine. Requires a project with its brand.md in place.

linkedin-post: LinkedIn post image

Goal: produce the PNG asset of a LinkedIn post image, at the chosen ratio, aligned with the guidelines.

This is a specialization of new-template with the LinkedIn constraints hard-coded. Same conventions: the Template contract (from brand-artisan), assets through brand(), fonts discovered in fonts/, export default ... satisfies Template.

Status of the dimensions. LinkedIn only officially documents one visual, at 1200×627 (1.91:1), for the link preview on Pages. For an image posted directly, LinkedIn publishes no dimensions: the 1080×1080 square and the 1080×1350 portrait are conventions (carried over from the advertising specs), not from the organic documentation.

0. Prerequisites (blocking)

The chain project -> template folder -> guidelines must exist:

• Resolve <project> (from the arguments, otherwise ask).
• Check templates/<project>/ and brands/<project>/brand.md.
• Missing guidelines or project -> STOP: ask for /new-project <project> first. No visual without guidelines (CLAUDE.md rule).

1. Frame it

• Which orientation? Ask. Default: portrait (4:5, takes the most height in the feed). Otherwise square (1:1) or landscape (1.91:1).
• Default slug linkedin-post (or linkedin-post-<orientation> if there are several). Check that the target .tsx does not exist.
• Read brands/<project>/brand.md: palette, type, logo variants, don'ts.
• Read brands/<project>/project.md if it exists: set the tone and the claims (don't invent figures or promises). If absent -> ask for the tone and the message rather than guessing.
• Ask for the message: short headline + standfirst (1 sentence). No paragraph.
• If the project already holds a .tsx, read it as a style reference.

2. LinkedIn constraints (to respect)

Orientation	Size (px)	Ratio	Status
Portrait (default)	1080x1350	4:5	Convention (ads specs)
Square	1080x1080	1:1	Convention (ads specs)
Landscape	1200x627	1.91:1	Official LinkedIn (link preview)

• Format: PNG or JPG, opaque background.
• The post's text (body, link) lives outside the image, in the publication: don't write everything into the visual. One idea per card.
• Legible when small: the LinkedIn feed displays narrow on mobile. Large headline, short standfirst, strong contrast, safe area of about 80 px.
• LinkedIn tone: a professional audience. Favor a standfirst carrying added value (an insight, a data point, a business benefit) over an aggressive pitch.

3. Write the template

templates/<project>/<slug>.tsx, with colors as constants taken from the guidelines. Pick SIZE according to the orientation. Skeleton:

import type { ReactNode } from "react";
import { brand, type Template } from "brand-artisan";
// import { readFile } from "node:fs/promises"; // if you load the mark

// Pick according to the orientation:
const SIZE = { width: 1080, height: 1350 }; // Portrait 4:5 (default)
// const SIZE = { width: 1080, height: 1080 }; // Square 1:1
// const SIZE = { width: 1200, height: 627 };  // Landscape 1.91:1

// <Project> guideline palette (from brands/<project>/brand.md).
const INK = "#......";

function render(): ReactNode {
	return (
		<div
			style={{
				width: "100%",
				height: "100%",
				display: "flex",
				flexDirection: "column",
				justifyContent: "center",
				padding: 80, // safe area
				backgroundColor: INK, // opaque 
			}}
		>
			{/* logo + large headline + short standfirst, strong contrast */}
		
	);
}

  { : , : , render }  ;

Shared conventions: assets through brand("<project>/..."), fonts discovered in fonts/; a missing font -> the "missing font" appendix in new-template, never silently. Keep the code minimal.

4. Verify

• npm run typecheck -> green.
• npm run build -> writes out/<project>/<slug>.png.
• Check the PNG: exact dimensions for the orientation, opaque background, correct ratio (4:5 / 1:1 / 1.91:1).
• Preview: npm run dev then /<project>/<slug>; check legibility shrunk to the width of a mobile feed.

Success criterion: a PNG at the dimensions of the chosen orientation, opaque, legible when small, professional in tone, and using only colors and type from brand.md.
