Nothing to see there. Move along.
Private is a CRUCIAL part of your Mac and deleting it would be disasterous.
Stop mucking about in the innards of your system where you have no business being!
While it is true that /private is part of macOS, it's not true that
everything inside the /private directory is a part of macOS or isn't something that shouldn't be there.
I don't see why this person has no business reviewing important configurations for various protocols that themselves are allowed to run amuck on macOS in large part thanks to the attitude that such knowledge is privy only to worthy developers. It just prevents newcomers from learning and enables malware to thrive in the shadows.
What's important to note:
--that these folders do hold important configuration files for various programs which do interact with the OS at a level which most would consider having potential to be a vulnerability
--at the same time these configuration files, etc. are NOT protected by the easily bypassed I mean impenetrable fortress know as System Integrity Protection
So basically they're important system files, where "junk" could throw a party, and are within the moderate protections of SIP. Why then wouldn't someone want to know what these files are and for that fact what should and shouldn't be there, which is no easy tasks thanks to this "you're not qualified to even think about it" nonsense that is the quick reply to a thoughtful answer to legitimate questions which many times are beyond the scope of most anyone since they're all incredibly complex programs/protocols and often only a handful of people are experts on the subject especially as time goes on and things from the 1980's linger with ever an ever shrinking minuscule user base, other than hackers.
This all is significant because for Agentx aka Agent Extensibility Protocol which is a standard related to"collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior" has
7 official CVE-ID vulnerabilities according to the CVE database (the official source for these things). 4 of which are given the highest level of threat potential and 3 of the 7 threats are rated as 10/10.

But really don't go mucking about there unless you are a member of the developer elite. You have no business as your computer utilizes a magical stealth firewall.
