I'll just post bots as I can be fucked to make them
Here is the first bot I've ever made and it works flawlessly.

It is a bot made for avoiding archers, it will run around in a 3x3 box and tell the archers that you mean business.
Make sure you have over 50 hunger and have a 3x3 space around you to run.
