Describe the enhancement you want to request

Skill usage is pretty mysterious right now. You have no idea which ones got used and which ones didn't (you have to dig in the messages shown in TUI). Sometimes I notice the code written by opencode doesn't follow the rules I define in my skills, and I end up spending time trying to figure out which skills were actually called and which weren't, just to understand if I need to improve a skill's description or its content.
