<p>Here's my new deep dive on why you need to build your product for AI agents first.

I spent a decade obsessing over intuitive user experiences (and I still do!).

But the "user" in UX is quickly becoming an AI agent instead.

For example, instead of visiting @mercury, @linear, or</p>

A deep dive arguing that AI agents are rapidly becoming the primary 'users' of software products, displacing human-first UX assumptions. Covers a primer on APIs, skills, and MCPs, a 5-step framework for building agent-first products, and actionable steps for this week. Uses examples like Mercury, Linear, and Granola to illustrate how users increasingly delegate product interactions to AI agents via natural language.

Here's my new deep dive on why you need to build your product for AI agents first.

I spent a decade obsessing over intuitive user experiences (and I still do!).

But the "user" in UX is quickly becoming an AI agent instead.

For example, instead of visiting @mercury, @linear, or @meetgranola, I just text my agent:

→ "Add my Mercury finances to your report."
→ "List my Linear tickets in your briefing."
→ "Takeaways from my meetings today?"

For many products, AI agents will be your first users, not humans.

My new deep dive covers:

☑️ APIs, skills, and MCPs: a quick primer
☑️ 5 steps to build for AI agents first
☑️ What you can do this week
