Do we have some kind of tips and trics doc/wiki/etc?

Hello there, a human writing this w/o the help of IA just to keep my English skills sharped. That being said, I'm looking for some kind of doc or similar with some tips & tricks to make my experience even better, for example,. how to reduce token usage, comparasion between skills, etc, etc, etc. "must have angents", if any. Right now there is a lot of information but I feel it's so disperse and incomeplete. I found https://github.com/awesome-opencode/awesome-opencode but is just that, a curated list of external sources. not exaclty what I'm looking for.

BTW, I know you are reading this while you arent(s) are working for you ;)

Thanks.
