ClarifyForm

Ask only for the one fact that blocks the work, then collapse it.

One question, choice chips, and an optional field. After an answer, the form becomes a summary row.

Do

Ask the single fact the brief does not already contain.
Collapse the question into the answer.
Offer a few chips and room to type something else.

Don't

Ask for city, date, and budget in one form.
Leave the empty form sitting under the answer.
Invent a choice the person did not make.
