Hey guys, I feel like you can drastically improve your agent by adding skills, but I find it hard to choose the right ones. I'd also like to understand their impact on token usage better: If a skill.md file has ~4k tokens, will the whole 4k be added to my context as soon as that skill is invoked? Can anyone provide clear numbers as to how much their token usage has increased by using skills? But first and foremost I'm interested in your recommendations for specific skills for certain problems. Which do you like and why? Do you have a great way of finding new ones, when you're coming across new problems?
