Also, how would I be able to give a creature the ability to sense all creatures that have(or lack) a certain tag without sight or hearing?
I have no idea whether or not it is possible in adventure mode, but it is defiantly possible in fort mode, but only with the following tags BLOODSUCKER, CAN_LEARN, CAN_SPEAK, CRAZED, EXTRAVISION, LIKES_FIGHTING (or LIKESFIGHTING), MISCHIEVOUS (or MISCHIEVIOUS), NO_CONNECTIONS_FOR_MOVEMENT, NO_DIZZINESS, NO_DRINK, NO_EAT, NO_FEVERS, NO_PHYS_ATT_GAIN, NO_PHYS_ATT_RUST, NO_SLEEP, NO_THOUGHT_CENTER_FOR_MOVEMENT, NOBREATHE, NOEMOTION, NOEXERT, NOFEAR, NONAUSEA, NOPAIN, NOSTUN, NOT_LIVING, NOTHOUGHT, OPPOSED_TO_LIFE, PARALYZEIMMUNE, SUPERNATURAL, TRANCES, UTTERANCES
What you do is that you make an interaction that has [IT_REQUIRES:one of the above mentioned tags]. Let's take NOTHOUGHT. you can then use the CDI tag [CDI:VERB:N/A:has detected a creature with no sight:N/A].
So what happened here is that in fort mode when the creature comes within range (range is defined by CDI:TARGET_RANGE ) of a creature with the NOTHOUGHT tag it will display the message "creaturename has detected a creature with NOTHOUGHT"
unfortunately you won't know what it is, or where it is, you will only know that it is somewhere in range and the AI won't know anything. It is possible to figure out what it is by using CDI:TARGET_VERB but, I don't know how the verbs tokens actually work so I don't want to talk about them too much.
here is a link where you can do more reading

The reason why I had my doubts about adventurer mode is because in adventure mode you have to activate your interactions and select your target and I don't know whether the game will allow you to do that if they can't see the target.
