Sensitive files should be reduced before upload so the task receives only what it needs. Full documents often contain personal data, annexes or side information unrelated to the current question.
Select relevant pages, remove unnecessary details where possible and use the right workspace and roles.
Start with a narrow boundary: which website, space, file, recipient or decision is affected? This makes the task reviewable instead of turning it into a broad catch-all request.
A useful work order is: “Identify which parts of this file are needed for the task and which sensitive details should be removed or ignored.” For important cases, add that uncertainties must be marked visibly instead of being filled in silently.
Pay special attention to files, sources, responsibilities and expected output format. These points decide whether the result is only useful for the moment or can be found, checked and continued by the team later.
Do not upload complete confidential files when a smaller excerpt would answer the question.
Less sensitive material lowers risk and can improve answer quality.
