LOWChatGPT-User allowed
robots.txt permits ChatGPT-User (OpenAI's user-initiated live fetcher) at the site root. Explicitly allowing ChatGPT-User removes ambiguity about whether ChatGPT can fetch pages during user actions.
What this check looks for
ChatGPT-User is the user-agent OpenAI uses when ChatGPT fetches a page in response to a user's action (e.g., 'open this product'). Per OpenAI's bots doc, these user-initiated fetches MAY ignore robots.txt — so a Disallow doesn't necessarily prevent the fetch. We still surface it as a soft signal: a well-configured store explicitly allows ChatGPT-User so the policy isn't ambiguous.

The spec it's pinned to
OpenAI bots — ChatGPT-User
OpenAI's bots documentation lists ChatGPT-User as the user-agent for user-initiated live fetches from ChatGPT. OpenAI notes these fetches MAY ignore robots.txt, so blocking it is advisory rather than a hard gate.
