Treat it like a junior, not a tool

The productivity unlock with Claude Code is not the model. It is using senior-design feedback patterns on a non-human collaborator.

Designers who plateau with AI co-pilots usually treat them like an autocomplete. Tool in, output out, edit, repeat. The designers who get a real productivity unlock are the ones who treat the AI like a junior. Same patterns. Same critique structure. Same gentle insistence.

Concrete observation beats abstract direction

A junior designer told to make it more elegant produces nothing useful. Same is true of the AI. Tell it the spacing under the button is twelve pixels and you want eight, you get eight. Tell it the gallery is feeling cropped and you want the natural image size preserved, you get the right CSS. Be specific about the bug, not the vibe. The model converges fast on a named problem. It flounders on a named feeling.

Use git as the undo button

Working with a junior, you accept that some directions will be wrong, and you have a lightweight way to roll them back. Same here. Commit before any structural change. Push to a branch before any speculative redesign. The agent is more useful when you are willing to throw away its work than when you are protecting it. This looks worse than before, put it back is a complete instruction in a working session, not a failure mode.

Critique by example, not by principle

Match the density of this list. Match the type scale on that page. Use the chrome from this component. The model is excellent at copying a real artifact in the codebase and bad at internalizing a stated rule. Show it where the answer already lives. The same trick I use with junior designers turns out to work on the agent.

The general principle

The AI is not a tool. It is a collaborator with a particular cognitive profile. Match your communication to the profile. Specific over abstract. Example over rule. Reversible over precious. The teams getting the most out of these systems are running senior-design feedback loops at a pace no human collaborator can match. That is the unlock. The model was always there.
