Here's the part no tool can do for you: deciding whether the answer is actually right. Cowork can search widely and write a clean brief, but on fact-dependent tasks it can be inconsistent — a date slightly off, a number pulled from the wrong row, a source that doesn't quite say what the summary claims. You are the human in the loop, and verification is your job.
Start by making the work checkable. Ask Cowork to cite its sources — links next to claims, not just a list at the end — so you can trace each statement back to where it came from.
