SkriptCanBuildCheck was created after noticing the high latency of SkBee’s on block can build check: syntax. Its goal is to support mass lower-level build checks faster than SkBee’s implementation.
With SkBee’s event, each on block can build check: handler appears to be evaluated until the relevant clause is reached. For example:

on block can build check:
if %event-block% is stone:
[...]
else:
stop

This became expensive during large low-level block checks and could noticeably impact TPS.
I noticed this while investigating a separate issue where Skript no longer appeared to perform low-level checks for on place, which allowed infinite items to fall through at Skript’s own level.

Note: using `%event_block%` is also expensive because it forces conversion through a string representation instead of working with the event block directly.

This plugin supports both singular materials and material families.
