I just spent an embarrassing amount of time trying to figure out where {{ agent_id.value }} was coming from:
using the links at the bottom of the State panel (window? meh) and i eventually got this variable in it:
but it doesn't say where it originates from either 
. I've been working in a module so long I forgot it was a module and had inputs 
Hey @bobthebear! Sorry to let this one sit for so long. 
I have a couple of ideas for how to make this more clear, but am curious to know if you have a vision or ideal solution. Something like this.agent_id or MyModule::agent_id?
Thinking about this more, maybe it would be more logical to just make these variables searchable in the State inspector. 
I've passed this feedback on to the team and will let you know when there's some movement!
