    Why it is in this group

    • The input takes a statement or command to run (input.code), which can change anything it can reach.
    Description, as the server wrote it
    Paste Stripe integration source code (a webhook handler, a checkout-session-creation route, or both concatenated) and get back pattern-based findings for the most common integration bugs: missing webhook signature verification, missing customer.subscription.updated handling (the single most common bug -- dunning marks a subscription past_due/unpaid, not canceled, so a handler that only reacts to .deleted leaves non-paying customers with access forever), missing checkout metadata/client_reference_id, and premature customer creation. This is regex pattern matching over text, not a real parser -- treat a clean result as 'didn't find a problem', not a guarantee. Nothing pasted is stored.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
