Ask HN: Recommended Gemini CLI extensions/skills for token consumption

Hello guys, recently I decided to go for a Google One AI Pro subscription. I did this mainly to use gemini-cli. Even though I don't regret about this decision, I think I might make a better use of the tool. Basically I am looking for suggestions about making gemini-cli more efficient. For example I tried the caveman extension and I know it decreases token consumptions but I don't really like it, so please if you can give me any suggestion about this I will appreciate it
