When preparing a description of a stamp, I would keep an AI suggestion separate from the information confirmed in a catalogue. An issue date or a catalogue reference needs a source, even when the answer sounds certain. If the source cannot be found, I would leave that detail out of the description.

For readers using these tools, Evgenii Arsentev explains this problem in his guide to AI hallucinations. He writes about AI agents and practical ways to work with them. This is a general guide, rather than a reference for Ceylon or Sri Lanka stamps; the philatelic details still need checking against specialist material.
