Other tips: I still had issues going too granular with GOAP actions at the start, so I recommend keeping your actions as coarse as possible. It's still a tool that you use with your AI designer hat on, it doesn't do everything on its own. But the power of being able to throw in a new goal, maybe one new action, and have the existing actions solve all the other prerequisites, is amazing. Defining world properties and states is a muuuuuuch lower mental load than using utilities for actions.

I wrote it all with performance in mind, and it seems to run fine. Basically lots of caching (each world property is only evaluated once per AI per tick then re-used, shared values are cached for all then re-used, etc); eliminating invalid paths early; and searching backwards from the goal instead of forwards from the current world state. I test with 4 AI players on an old i3 laptop processor from ~2016 without issue.
