Professors at the University of Illinois just dropped a 22-page PDF on agents that write their own Claude Code skills. generate a skill → a separate verifier writes its own tests → fix what fails → repeat stop hand-writing skills. the agent writes them and checks itself. > one agent builds the full multi-file skill, not a single function. > a second agent, blind to the code and the real tests, invents its own checks. > the verifier writes harder tests instead of leaking the answer. > it rewrites itself until it holds. read the paper first, then the article below.
