There seem to be various global tables you can use in a lua module, e.g. Player. I can discover what functions I can call easily enough from these tables, but there's no documentation on arguments or anything like that. Also, I've noticed that a lot of existing modules access properties on these tables, however I can't seem to log out these table entries.

Is there any kind of documentation for these tables, or is it going to be a process of reverse engineering them by hand like I've been doing so far?

There is some API documentation in the wiki and more on github. It may not all be up-to-date and incomplete, but its a good point to start. The bots source is also a good source of examples on what game objects and functions are available. If you have specific questions, you can join the discord chat and ask there.
