better consistency could be achieved if checks_agent.c is moved to shared library to be reused both by server and zabbix_get. But it should be decided if needed.

Glebs Ivanovskis Yes, src/zabbix_server/poller/checks_agent.c get_value_agent() and src/zabbix_get/zabbix_get.c get_value() have a lot in common and it would be beneficial to merge them into something more general-purpose (and move to src/libs/zbxcommshigh perhaps), especially from the point of view of consistent error messaging and failure analysis (see ZBX-10613).

this is expected to decrease the chance of bugs and different behaviour across the components.
