Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_graphic safely

update_graphic Rate-limited

update_graphic stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
