Build a feature with a model, out loud

The baseline AI round. You are scored on what you asked for and what you expected back.

The question

Build a CSV import feature: the user uploads a file, sees a preview with validation errors highlighted, fixes them inline, and commits the import.

Use whatever tools you normally use. Narrate the prompt before you send it and what you expect back, then read the output aloud before accepting it.

45:00Commit to an answer before you open the solution. Reading it first teaches you to recognise good answers, which is not the skill being tested.
