Who this is for

Built for founders who know there's more in this.

You use AI every day and still feel short of what you were promised.

You're stuck using it like a chatbot, re-explaining yourself every time.

You've tried more tools and better prompts, and the results still don't stick.

And you can feel it: the founders who've worked this out are pulling ahead, and the gap is widening every month.

You can see there's a step change here, you just haven't had the room to make it.

In one day you build the system that makes AI work for you, and you leave knowing exactly how to keep it growing.

How the day runs

One full day, start to finish.

Morning · AI literacy foundations
9:00–9:30

Arrival & coffee

Doors open at 9:00. Settle in, meet the group, and grab a coffee before we start.

9:30–9:45

Welcome & scene-setting

Introductions and framing. We recap the core thesis: AI is probabilistic, and building the harness around it is the real job.

9:45–10:30

How AI actually works

The mental model that makes everything click. Non-determinism and temperature, reasoning models, context rot, file formats, and the horse-and-harness analogy in full.

10:30–11:45

The full spectrum of Claude

The complete architecture: Chat, Projects, Cowork and Skills, Agents. Tools and the MCP layer, the read-versus-write distinction, and instructions versus knowledge versus memory.

11:45–12:00

The human skills for effective AI use

The other half of the job: externalising your thinking, building context deliberately, and judging what AI should and shouldn't handle.

12:00–12:45

Lunch

Provided. Decompress, compare notes, and come back ready to build.

Afternoon · build your knowledge harness
12:45–13:45

What a knowledge harness is

The full conceptual model before you build it: what the knowledge harness is, how it plugs into Claude, progressive disclosure, and a live look at a fully-built system.

13:45–14:30

Run the Second Brain Architect skill

Install Obsidian and run the skill. Work through the question blocks to generate your folder structure, CLAUDE.md, and first Maps of Content, built around your own business.

14:30–15:00

Continue & review

Finish, troubleshoot, and review as a group. Everyone leaves this block with a working vault.

15:00–15:20

Core skills walkthrough

A live demo of the skills that make the system useful day to day, shown as habits: what to do after a meeting, after a session, and after an idea.

15:20–15:30

What a skill is, and how to build one

From using skills to owning them. The anatomy of a skill, a simple one built live, and the template to create your own.

15:30–15:45

Break

15:45–16:15

What happens next

A concrete plan for the first two weeks, plus the three weekly 45-minute support calls and the shared Slack channel that run after the day.

16:15–16:30

Closing

What AI fluency looks like in practice: not technical proficiency, but architectural instinct. The tools are interchangeable. That judgement isn't.

What do I bring?
