How to Make Viral LinkedIn Posts with Claude Code

If you want Claude Code to write content that sounds like you, you have to tell it who you are. Not once in a prompt - permanently, in a file it reads every time. That file is your profile.md and it's the single most important setup step in this whole workflow.

What goes in your profile.md

Two sections

Keep it updated

It's a living document

The hook is the first two sentences of your LinkedIn post. It determines whether anyone reads the rest. Claude Code pulls from a hooks.md file to decide how to open each post - which means the quality of your hooks file directly determines the quality of your posts.

What a hooks file is

A reference library of strong openers

What makes a strong hook for LinkedIn

Numbers and specifics outperform vague statements

What to avoid

The skill file runs the whole process. You give it a topic or a script, it reads your profile and hooks files, generates three post options, and lets you review, edit, approve, or regenerate each one before anything gets published. You stay in control. Claude does the drafting.

Two ways to create a post

Option A: From a YouTube script or existing piece of writing

Option B: From a topic or idea

Reviewing the three drafts

You review every post before it's approved

What to look for when reviewing

The photo selection system

Name your photos as descriptions

Once you've approved your posts, Claude Code can publish them directly to LinkedIn using Playwright MCP - a tool that controls your browser automatically. It navigates to LinkedIn, pastes the post, uploads the photo, and schedules it for your preferred time. You don't touch it.
