What you'll learn

Why agents prefer CLI over other interfaces

It's not just speed and tokens. Learn what makes CLI the most streamlined interface an agent can use.

The downsides you need to know about

CLI isn't right for every product or every agent. Know when it fits and when other interfaces work better.

What good CLI design looks like

Tour real CLIs agents love and ones they struggle with. Consistent flags, helpful errors, clean output.

How to add a CLI to your product

Where to start with design. What tools are available and how to get started building one for your own product.

Why this topic matters

Command-line tools are the leanest interfaces an agent can use, and every coding agent supports them. Your product probably needs it, but no one talks about CLI UX, even though it's never been more important. There is deep design wisdom dating back to the Unix philosophy, and agents benefit from it all. You'll learn what makes a great CLI, why agents love them, and principles no one else teaches.

Founder, Level 250 | 3x VP Product Management

I’m Emmanuel, an entrepreneur, product management executive, and consultant at Level 250 with over 15 years of experience shaping products.

I’ve led large API programs in fintech for Verisk, Moody’s, and Precisely, and served as VP of Product for some of the world’s most influential API tools - like API Blueprint at Apiary (550,000+ APIs), Oracle’s first Cloud-Native API Gateway, and Swagger at SmartBear (750,000+ APIs).

Over the years, I’ve consulted with everyone from Fortune 500 CEOs to startup founders, engaging with thousands of PMs, developers and consumers to help them build winning products and ecosystems.

My passion is to make products more impactful and user-friendly, which is why I created Build AI-Ready APIs: A Hands-On Workshop for Engineers and PMs: to share my lessons learned and help Product Managers and Engineers fast-track their careers.

Join me to gain practical insights, avoid common pitfalls, and learn how to deliver Developer Products that enable great user experiences, without repeating the mistakes I’ve already made along the way.
