How To Build An Agentic OS (The Practical Path)
Julian's free one-hour YouTube course builds an agentic OS live on camera — watch it here.
This page is the condensed field manual: the order that works, and the traps.
Hour one: the shell
Prompt your best model (the course uses GPT-5.6; Claude works equally) to scaffold a local dashboard — mission control page, one tab per agent, run it on a localhost port.
Local matters: this thing edits files; it must not be a public website.
Template shortcut: members install the maintained zip in .10 minutes instead.
🔥 Want the exact how to build an agentic os setup I use?
Inside the AI Profit Boardroom you get the full step-by-step tutorials, the installable Agent OS, weekly coaching calls and 4,000+ members building real automations.
Day one: wire what you already own
Plug in subscriptions before anything new: Claude CLI, Codex, Hermes (free), a local model via Ollama.
No new API bills.
Name every conversation; fork parallel chats per feature so the video agent and the SEO tab get built simultaneously.
Week one: memory + first workflows
Point every agent at one Obsidian vault (read context, write logs) — that single change makes agents feel personal.
Then audit your week and build ONE tab per repeated job.
Test by using, not by trusting "done" — the course catches a blank-screen bug exactly this way.
The rules that keep it alive
One builder-agent per repo at a time (two agents overwrite each other).
Everything hideable — models rotate weekly; your OS shouldn't care (Fable 5 vanished mid-cycle; swapping took two minutes).
Galleries for every output.
Delete buttons everywhere.

FAQ
How long does building an agentic OS take?
A working shell in an afternoon with a frontier model coding; a genuinely daily-driver system in about a week of iteration. The template route compresses day one to ~10 minutes.
What stack should the dashboard use?
Whatever your coding agent scaffolds fastest — typically a local Next.js/React app. The stack matters far less than running it locally and keeping features modular.
What's the first workflow to build?
The job you repeat most. Audit your week, pick the top time sink (content, research, leads, reporting), make it a one-click tab. Ship one before building six.
Do subscriptions cover it or do I need APIs?
Subscriptions + free local models cover 100% of the build in the course. APIs are optional accelerants, not requirements.
