Design agents don't have taste. They don't need to.

Every few weeks someone asks me whether design agents will replace designers. The question assumes the agents are trying to do the same job. They aren’t.

A design agent does exactly what it was built to do. It gives you the most likely answer. That’s not a flaw you can prompt away. It’s the design.

Agents make the average on purpose

When you ask an agent for a pricing page and specify nothing else, it returns the statistical middle of every pricing page it has seen. Three tiers. The middle one highlighted. A toggle for annual billing. A row of checkmarks.

Nothing about that is wrong. It’s the center of the category, delivered in seconds.

If nothing is specified, the agent returns the middle. Every time. Its whole job is to reduce surprise, and the least surprising answer is the one everyone else already shipped. I wrote about where that leads in the authorship post: a product nobody decided, that could belong to anyone.

So the question isn’t whether agents are good at design. They’re very good at the average. The question is whether the average is what you want.

For a startup, it almost never is.

Taste is a set of decisions

People talk about taste like it’s a mood. A vibe some designers have and others don’t.

I think it’s more concrete than that. Taste is the set of decisions a person makes on purpose. This color, for this reason. This much space, not that much. This interaction, because our users are anxious at this step. And, just as often, this thing does not go on the screen.

That last part is the one people forget. Taste is mostly subtraction. It’s the feature card you cut because three of them is what everyone does. It’s the gradient you refuse because nobody could explain why it was there. It’s the animation you kill because it’s charming the first time and annoying the tenth.

An agent can’t make those calls, because making them means going against the most likely answer. That’s the one direction it’s built not to go.

Where agents actually help

Here’s the contrarian part. I don’t think that makes agents useless for design. I think it tells you exactly where they’re useful.

Agents are useful when taste is written down as rules they’re held to.

Once the decisions exist outside someone’s head, an agent can follow them at a speed no person can. Tokens for every color, size and duration. Components with their real states. Refuses: short “we will never” rules, each with a reason. “No uppercase labels over headings; we want the page to read like a person talking.” An agent can work inside that. It can produce the fortieth screen in a flow that respects every decision made on the first one.

Without the rules, the agent drifts back to the middle. With them, it holds the line you drew.

That’s also why we built Slop Patterns, a public library of AI design anti-patterns. It’s a list of what the average looks like, written down so a person or an agent can check against it. Knowing what you refuse is half of knowing what you want.

The job moves

If agents can take the volume, what’s left for the designer?

The part that was always the job. Deciding and reviewing.

The work moves from making every screen to deciding what the screens should be, and then reviewing what comes back. Writing the rules. Choosing the one alternative worth keeping out of five. Looking at an agent’s output that follows every token and still asking: is this ours? Would we have chosen this?

That review is harder than it sounds. Agent output often looks finished. It’s polished, consistent and technically correct. The skill is noticing when polish is covering for a decision nobody made. That takes someone who has made a lot of decisions and lived with the results.

It also changes who you need on a team. Fewer hands producing screens. More people who can say no with a reason.

What you can hand off, and what you can’t

Here’s the line I use with every team we work with.

Taste can’t be delegated. Volume can.

Hand agents the variants, the states, the spacing fixes, the fortieth screen. Keep the decisions with a person who is accountable for them. Write those decisions down so the agents can see them. Review everything that comes back.

If you do that, agents are a way to hold your standard at a pace your team couldn’t manage alone. If you skip it, they’re a very fast way to become the average.

The agent will never ask what you meant. It will just give you the middle.

Decide first. Then let it run.
