Write down the exact format, number, decision, or artifact you need. This prevents unnecessary work and makes it easier to choose between the two tools.
Use representative values or a copy of the source—not your only copy. Remove information the task does not need, especially personal or confidential data.
Check labels, units, assumptions, and selected options. Review the first output before using it as the input to another tool.
The second tool should solve a distinct next task. Do not process the same input twice merely because both tools appear in the same guide.
Open the output separately, compare it with the source, and confirm format, order, quality, and file size. For important legal, medical, financial, immigration, academic, or production decisions, confirm with an authoritative source or qualified professional.
