Pop it into AI and it will tell you if the expression is correct or not, and be specific with the AI what CF plan you're on, as what you can do in an expression changes per plan.
You can do a lot of things with a CF expression, but you should go read the CF docs on how expressions work, ie. AND will be processed before OR.
Don't try and complicate an existing rule, because an existing rule may be simpler written when you add something to it, changing everything you had to a different logic.
Code:
(
(
http.user_agent contains "GPTBot"
or http.user_agent contains "ClaudeBot"
or http.user_agent contains "PerplexityBot"
or http.user_agent contains "Google-InspectionTool"
or http.user_agent contains "AdsBot-Google"
or http.user_agent contains "CCBot"
or http.user_agent contains "facebookexternalhit"
or http.user_agent contains "Twitterbot"
or http.user_agent contains "DeepSeekBot"
)
and not cf.client.bot
)
or
(
cf.client.bot
and (
http.user_agent contains "GPTBot"
or http.user_agent contains "ClaudeBot"
or http.user_agent contains "CCBot"
or http.user_agent contains "DeepSeekBot"
)
)
If BLOCK, then the top half blocks pretenders and the bottom half would block legitimate. Change it to SKIP and they do the same thing for SKIP action, one does one thing, the other half does the opposite.
My Point: Adding things that do the opposite, in the same rule, can get complicated.
Keep It Simple Stupid is my principle I like to live by, especially with CF rules. Less is often more.
If you use AI to help you, ask it to make the rule do what you want, in the shortest, simplest way, possible, using what your plan has available to it.
It's like the list of 700+ bots on cf.client.bot, if you only want to use 50, then its easier to allow 50 and block the rest, not block 650+ and allow the rest.
