Questions about this workflow
Can the workflow determine whether a rule is safe?
It can report the available information, but safety depends on context and evidence that may not be present. Ask it to identify what needs human verification.
What starts the review?
An HTTP request to the Notis webhook starts it; there is no Cloudflare trigger event listed for this package.
