Intercom’s design team published numbers that show what happens when agents take over the build. John Moriarty, writing for Fin Ideas:

At Intercom, how we design and build software is unrecognizable from 12 months ago. Our engineering team is already at the point where 90% of pull requests are authored by Claude Code, part of an internal initiative called 2x, where the explicit goal is to double productivity using AI.

When 90% of your pull requests are AI-authored, the designer’s job changes whether you update the title or not. Moriarty’s framework for what comes next:

As the rate of execution accelerates, the role of design becomes sharper. Agents can generate artefacts, but they cannot decide which problems matter, set intent, resolve trade-offs, or hold the bar for quality. Our craft shifts with that reality. […] Agents will own the middle, the build. Design’s value concentrates at the edges, deciding what to build and then determining whether the output is good enough.

Design’s value lands at the edges, not the middle, and Intercom is already adapting their infrastructure to match. They’ve repositioned their design system as what Moriarty calls “agentic infrastructure”:

In a world where Agents write most of the code, design systems become the infrastructure that protects quality. Components, libraries and guidelines are the foundation that Agents and teams build on top of. The better the system, the better everything produced. Strong systems allow quality to scale without adding review overhead.

This tracks with the argument that design systems are becoming AI infrastructure—and Intercom is running it in production. The design system is the quality control layer that lets agents ship at speed without designers reviewing every screen.

Moriarty’s full piece covers how they’re restructuring day-to-day work—moving designers into code, treating Figma as a whiteboard, running structured AI fluency training. Worth a full read.
