Separate claims from presentation
Read the output once for meaning, then mark the statements that could affect a decision: prices, dates, availability, measurements and comparisons. These deserve direct checking. A structured table or confident paragraph can make unsupported information look settled. Treat formatting as presentation, not evidence.
Open the source behind the claim
Follow the citation and locate the passage that supports the statement. Check that it concerns the same product, plan, country and period. Prefer the provider's current documentation for product entitlements and billing rules. If a source only mentions a feature in a navigation menu, it does not establish its limits or availability in your account.
Check what a summary left out
For a document summary, ask about a detail near the end, an exception and a condition that changes the main conclusion. Compare the answers with the original. A summary can be useful while still omitting a qualification that matters to your task. Preserve access to the full source instead of retaining only the generated explanation.
Make uncertainty visible
When a price requires login, say so. When a source cannot be reached, preserve the last confirmed information with its date and distinguish it from a fresh check. When two official pages disagree, describe the conflict rather than choosing the more attractive figure. Uncertainty is information your reader needs in order to make a sound decision.
Keep a small evidence trail
For work you will share, record the source URL, the date you checked it and the fact it supports. Recheck volatile details before publication. You do not need an elaborate archive for every sentence, but a future reader should be able to understand why the important claims were made. Our workspace profiles follow this same distinction between sourced facts and editorial judgement.
