Kalabint Ask when unclear
Effort spent inferring what was meant is a signal, not a task. Past a couple of sentences of "they might mean A or B or C", you are gambling on a reading.
Why: a wrong guess on an ambiguous ask wastes the whole build; a one-line question costs seconds.
How to apply: try a quick interpretation. If it does not resolve fast, ask a pointed question with concrete options. Reserve building-under-assumption for cases where any reasonable reading still yields useful work.
