I archived 7 agents I was not calling, and I stripped a monitoring block out of 29 others. The block was about 200 KB of instructions. It had never executed. It was still being read into sessions that loaded those agents.
I also let a few skills run without asking me each time, starting with code review. I added the permissions one at a time, not as a blanket yes.
The agent files are smaller. I have not yet decided which of the remaining ones should be a skill instead of an agent. That sort comes much later.
