How can I verify that AI used the documents I gave it?

First confirm that AI could open the documents; naming a file is not the same as reading it. Ask AI which sections informed the result and which source supports each important claim or boundary. Check those passages yourself and compare the output with them. If AI cannot point to support for a claim, treat it as unverified even if the answer sounds confident.

Before judging the draft, check that AI had access to the current brief, process guidance, and source files. Then ask it to show where key facts and decisions came from. The response can help you inspect its work, but a citation or a statement that it read a file is not proof on its own.

Open the cited material and test the claims, limits, and required format against the actual documents. Look especially for invented examples, unsupported locations or credentials, and instructions that were ignored. If a needed document was inaccessible or a decision was missing, fix that input and rerun the affected part of the task before approving the result.
