WHAT'S IN EVERY DROP
Three formats. One useful thing each week.
A real CLAUDE.md, ready to drop in
The exact context file behind a workflow we shipped that week. Sales research, exec assistant, ops triage, whatever the deployment was. Paste it into your own project and ship.
A prompt that's pulling its weight
Not a generic one-liner. The actual prompt we use in production, with the context that makes it work and the failure modes to watch for.
The story behind one of our wins
How we scoped it, what we tried first, what broke, what the client measured, and what we'd do differently. The kind of detail you can't get from a case study.
WHO IT'S FOR
Founders, operators, and teams running AI in their business. If you've shipped an agent and want to keep getting more out of it. If you're evaluating AI and want to see what good looks like before you commit.
Not for: people who want generic AI news, model-release recaps, or hype. We don't cover any of that.
FAQ
Frequently asked
How much does it cost?
Free. Drop your email, get the next Sunday's drop. Unsubscribe in one click whenever you want.
How often will I hear from you?
Once a week, on Sundays. Occasionally a second mid-week drop if we ship something time-sensitive, but the default is one email per week.
What's actually in it?
Three rotating formats. A CLAUDE.md you can drop into your own project, a prompt we use in production, or a deployment story from one of our client builds. Each one is short and lifts a single useful thing.
Who is it for?
Founders, operators, and teams running AI in their business. If you've shipped an agent and want to keep getting more out of it, the Brief is built for you. If you're brand new to AI, start with our manual at /manual.
