/**
|
|
* Safety check of the agent.
|
|
*
|
|
* The agent's output is untrusted: a manipulated model call (for example through a web page it read) may
|
|
* try to empty a page, plant a phishing text or swap a contact detail. This file judges what a change set
|
|
* would *do*, not what the model says it does. Everything here runs on the server, without a model call, on
|
|
* the replayed content (before and after), so splitting a deletion into many small operations, or choosing
|
|
* other tool arguments, changes nothing.
|
|
*
|
|
* - raijuAgentSafetyAssess(): blast radius, new text and changed contact details of a change set
|
|
* (called by raijuAgentValidate(), which stage, finalize and apply all use)
|
|
* - raijuAgentSafetyScanText(): patterns for scams, phishing, malware, hate, adult content, illegal goods
|
|
* - raijuAgentSafetyScreenRequest(): first line, on the user's own words ("delete everything on the home page")
|
|
*
|
|
* Levels: "block" cannot be staged, presented or applied (no override, also not for administrators);
|
|
* "caution" is shown in the review and needs one more explicit confirmation when applying.
|
|
* The word lists are heuristics (includes/ai/agent/safety-patterns.php); they are the cheap first line, the
|
|
* limits on amounts are the part that does not depend on wording.
