will check for any nearby dragon eggs, if found none kill players with it and look in it for chests. it will then check if it is in the end and try and kill the ender dragon. if it is not, in the end, it will search for a nearby ender portal and if it finds none it will get ender

This would be one of the most used baritone functions and will be the easiest way to get anything in minecraft.

Final checklist

• [tick] I have not used any OwO's or UwU's in this issue.

Everything but "check players' inventories" seems nice. I doubt the other players' inventories are viewable unless we count as an inventory the slots that are visual, like active slot, offhand or armor.

Yes, that's the only thing that might be a problem.
It would be fine if it is not possible but still a cool idea if it works.

Correct, the only information supplied to the client by the server in terms of inventory is anything that is visually represented.
