There are two versions of the same design-systems worry. One is about craft: AI can make an interface look considered without teaching anyone how the system works. Design-systems expert TJ Pitre pushes on the governance version: once the system is machine-legible and agent-friendly, who owns the calls the machines are allowed to make?
So when I say I have a beef with “agentic design systems,” understand that it isn’t a beef with agents. It’s a beef with one specific move that the term smuggles in, and that most people repeating it haven’t noticed they’re endorsing.
Here’s the move: handing the judgment layer of a design system to an autonomous agent loop that no human owns.
That’s the whole problem. Everything else is just tooling, and the tooling is great.
Design systems as AI infrastructure only works when the infrastructure still has an owner. Make the system machine-readable. Let agents generate, document, test, and check against it. But Pitre is correct that the library is only useful if the standards still have an accountable owner.
Strip away the Figma libraries and the Storybook instances and ask what a design system actually is. It’s a set of decisions an organization has agreed to and committed to enforcing over time. What does “primary action” mean here. When do we break our own grid. Does this thing deserve to exist as a component at all, or are we about to enshrine a one-off into the canon forever.
Those aren’t generation problems. They’re judgment calls, and they carry consequences the organization is accountable for, to its users, its engineers, its brand. A design system is, underneath all the tooling, a way of encoding collective judgment and holding people to it.
Pitre turns that into a test:
Which gives you a clean test for any “agentic design system” claim you encounter. Ask: what rejects the agent’s output, and who decided the rule it’s being rejected against? If the answer is a human-owned gate, it’s the real thing. If the answer is “another agent checks it” all the way down, you’ve built vibe coding with extra infrastructure and a more confident logo.
And that version is arguably worse than a person vibe coding in a scratch repo, because it launders drift through the authority of the system. The output looks sanctioned. It came from “the design system.” Nobody chose it.
In the end the invisible hand of the designer must still be felt.

My Beef with Agentic Design Systems
I build with agents every day. That’s exactly why this term worries me.
