Optical Endstop Tool Pickup Verification

My senior project comprises of putting E3D's tool changer hardware onto my printer of choice, which happens to be the HevORT.
Anyhow, I am looking to add tool pickup verification, so when my printer goes to pick up a tool, I am wanting to use an optical endstop (or any type of endstop for that matter), to tell the printer "hey you picked up the tool successfully".
How would one go about doing this in the firmware? I am thinking that the optical endstop would be on the tool pickup head, then a 3D printed "flag" on each of the tools that would interrupt the endstop.
From a hardware standpoint, I am using Duet 3 MB and 3HC expansion tethered to Raspi4 for SBC.
Thanks in advance.

if you can have it the other way round, with the switch on the tool itself, you'll be able to know which tool is installed and drop the tool off in the event of power loss etc.
You could query the input as part of the TPost file and flag accordingly.
You could also monitor the switches as part of the daemon file to ensure a tool hasn't dropped off mid print
