I can see compatibility with this/these mods.

Where the engineer would think about the tasks to be accomplished. Take these tasks and turn them into sentences like "It would be wise to increase my copper production" or "I should start a production of military packs".

I don't think that's easy to implement, but it's just a suggestion, and you're free to do what you like with it.

Hey, this was my instantly created thought bubble as well, seeing this mod. I could imagine some funny vanilla hints, too, like just a machine gun if you've teched it and run around with a pistol.

Perhaps if this mod had an interface that other mods could use, others could implement the "source of information" logic?

I like both ideas! They are quite hard to implement as it requires to analyze the current game state, versus the current implementation of "here's a list of 500 hard-coded thoughts, just pick a random one". Getting information from a task list mod is a step further, as it requires an interface to that mod first, and interpreting text written input is another step further.

I'll place this idea on the backlog, however I can't promise that this idea will be implemented.
