Nod. "This one will teleport whatever living thing you touch, and it's only going to teleport them to one of the pit traps I set up this morning, but intention-based is reasonable."
She begins casting, and as promised talks Ana through the whole process as she goes. The first step is to see what 'intending to teleport this creature' looks like, which requires asking Ana to imagine doing it. Then, the observed pattern is set up in a certain way so that the teleportation portion of the spell is only active when it's present, and stops as soon as it stops. The time pattern is used to add a second deactivation trigger; it's possible to work out what 'an hour from now' will look like from how the time-pattern is changing, and she arranges that appropriately. Next, the teleportation portion of the spell is set up, so that when the spell is active, any creature (a pattern the kobold has already memorized) who touches her (another memorized pattern, generalized in a specific way) is teleported to a specific (memorized) location-pattern.
The notification flashes are actually two separate spells in addition to that; one uses the beginning of the same intention thought-pattern as its trigger, and the other uses the end of it, and they're both also set to permanently deactivate after an hour.
She's through casting just as soon as she's done talking, and now they can go check the pit traps for animal volunteers.
