A sketch gives your idea a shape
A rough drawing can communicate relationships that take paragraphs to describe. It shows what belongs together, what should be prominent, and how someone might move between screens. But it does not explain every behavior. Pair the image with a short brief describing the audience, task, constraints, and uncertainty you want to explore.
Annotate the parts that matter
Number the screens and label navigation arrows. Mark required content and actions. Explain ambiguous marks. Distinguish “this must work this way” from “this is one possible layout.” Include at least one failure or empty state if it is relevant. Your annotations prevent the model from turning a guess into a requirement.
Ask for an interpretation first
Before generating the interface, ask the AI to explain what it sees. Look for misunderstood labels, missing steps, or invented features. Correct the interpretation before investing in polish. Current Claude Design guidance supports supplying images and wireframes as context; the quality of that context still matters.
Explore before committing
Request two approaches that differ in a meaningful interaction, rather than only in color. For instance, compare a guided sequence with a single editable overview. Discuss the tradeoffs with your team. Choose based on the question you need to test, then build a narrow prototype with clearly labeled sample data.
Test behavior, not your sales pitch
Give a relevant user a task and observe. Avoid explaining where to click. Record hesitation, errors, and requests for help. A small formative study can reveal usability issues, but it does not prove market demand. End with a decision and the next uncertainty to investigate.
