The foundation

Voice Profile Builder.

A Claude project file that analyzes your LinkedIn posts and builds a reusable voice profile. You build it once. Every pattern plugs into it.

Setup

How to use it.

1

Create a Claude project

Go to claude.ai, create a new project, and paste the Voice Profile Builder text into the project instructions. This becomes the system prompt.

2

Feed it your posts

Export your LinkedIn posts as CSV, or paste 15-30 posts as text. Include engagement numbers if you have them. The more data, the sharper the profile.

3

Save the output

Claude produces a performance analysis and a voice profile. Save the voice profile — you'll paste it into every future pattern conversation. Build it once, use it every week.

4

Use it with patterns

Every Friday, Shipped includes a new Unscriptable pattern. Paste the pattern alongside your voice profile, fill in the blanks with your material, and get a draft in your voice using a proven structure.

Output

What you get.

Performance analysis

Every post scored 0-100. Top performers, hidden gems, and the one metric that matters most for your content.

Voice profile

Your sentence architecture, vocabulary fingerprint, opening and closing patterns, tone, and thesis — the reusable API that patterns call.

Content categories

Every post tagged and ranked by engagement. See which content types your audience responds to vs. which ones you think are working.

The unscriptable part

What about your voice depends on lived experience — the thing a writing tool can approximate structurally but can't make real.
