Why this course

Most AI tutorials stop at the demo. This one goes to production.

A complete, ordered path that covers the parts most courses skip: verification, safety, evals, cost, and deployment.

Understand how agents really work

The model, the loop, tools, context, and cost — explained clearly enough that you can predict when an agent will succeed and why it fails.

Get real work done with agents

Write tasks agents can finish, use coding agents like Claude Code and Codex with confidence, and automate research, analysis, and busywork.

Build and ship your own

Write the agent loop from scratch, connect tools with MCP, coordinate multiple agents, and run them safely in production with evals and guardrails.

FAQ

Frequently asked questions

Can't find your answer? See the full FAQ or email us.

Do I need to know how to code?

No. Start Here, Agents for Everyday Work, and Agents in Organizations need no code at all, and How Agents Work and Prompting & Context Engineering explain every idea in plain language before showing any code. The build modules use TypeScript, but you can follow along by having a coding agent do the typing while you learn to direct and review it.

What exactly do I get?

Lifetime access to all 130 lessons across 14 modules (about 26 hours of reading), more than 200 copy-paste prompts, a hands-on exercise in every lesson, 7 complete capstone builds, progress tracking, and every future update to the course.

Is this a subscription?

No. It's a single one-time payment with lifetime access and no recurring charges.

Is the launch price really limited?

Yes. The $79 launch price applies only to the first 100 students. The seat counter on the site counts real, paid purchases. When the seats are gone, the price returns to $149 automatically.

Can I try it before buying?

Yes. 8 lessons are completely free, including the entire Start Here module, LLMs in Plain English, and The Coding Agent Landscape. No account required.

Which AI tools does the course use?

The principles work with any modern agent. Examples use widely used tools such as Claude Code, OpenAI Codex, Cursor, and the Claude and ChatGPT apps, plus the Anthropic API, the Claude Agent SDK, and the Model Context Protocol (MCP) for building. Where a lesson shows a specific product, it focuses on the skills that transfer.

Will I need to pay for AI tools too?

Many exercises work on free tiers. For the coding-agent and build modules you'll want a paid coding-agent plan or some prepaid API credit. The build exercises make small, short runs, and the course shows you how to measure what each run costs and set a spend limit before you start.

How is this different from free YouTube videos and blog posts?

It's a complete, ordered path instead of scattered tips: lessons build on each other, every lesson has a hands-on exercise, and the advanced modules (evals, safety, production) cover what most tutorials skip — the parts that make agents reliable enough to trust.

Built the way it teaches

This site, its checkout, search, and all 130 lessons were planned, written, reviewed, and shipped by AI agents — directed by one person who decided what to build and checked the results. That's the skill set this course teaches.
