Claude starts every session cold. It doesn't know who you are, what you work on, or how you want things written. The fix is a context library: a folder of files Claude reads before doing anything else. That's your Claude OS.

• A project folder - one home for everything. A git repo so Claude Code can track changes and you can commit your setup.
• CLAUDE.md - a file Claude reads automatically at the start of every session. What this workspace is, what you're working on, and how you want things done.
• Context files - who you are (user.md), how you write (writing-style.md), and what you're building (product notes, goals, audience).

Paste your current LinkedIn profile into Claude: About section, headline, featured. Ask it to rewrite everything. Sharper headline, stronger positioning, a bio that reads like a person wrote it. This is the actual work. The user.md falls out of it automatically - Claude already knows your niche, audience, and voice from the rewrite. Ask it to capture that in a file before you close the session.

• Name and headline - what you do and for whom, in plain language
• Niche and audience - who you write for on LinkedIn, what they care about
• Core pillars - the 2-3 topics you post about consistently
• Voice markers - how you sound: first person, specific, self-deprecating, no jargon
• Forbidden words - what you never say: em dashes, "leverage", "game-changer", "unlock", "synergies"
• What you never do - no engagement bait, no philosophical closers, no questions that look desperate at low follower counts

Even with a user.md, Claude's default output often sounds like AI: too polished, too structured, too many insights that land too neatly. A writing style file fixes this by giving Claude a precise model of your sentence rhythm, the things you say, and the things you never say.

• Sentence rhythm - how long your sentences tend to be, and whether you mix short and long or stay consistent
• Openers - how you typically start a post: a story, a claim, a question, a result
• Tone - direct, warm, dry, technical, conversational - and where that shifts depending on the topic
• Forbidden words - the words and phrases that don't sound like you
• Closers - how you end: a call to action, a punchline, a question, or nothing at all
• Formatting habits - do you use line breaks, bullets, bold? Or flowing paragraphs?

LinkedIn replaced its entire feed algorithm in 2025 with 360 Brew: a 150-billion-parameter model that scores each viewer individually. It no longer shows your post to everyone interested in a topic. It asks: is this the right post for this specific person, right now?

Micro-niche wins. Broad loses. And success isn't measured in the first 24 hours - DMs from content typically arrive 3-5 days after posting.
