https://github.com/pjlsergeant/byre can add small but very convenient layer around whichever agent you want, initially trapping it in a specific folder, but you can easily mount more, firewall it, bring in MCPs and skills, or whatever. It's unambiguously AI-assisted, but a very very great deal of thought and work has gone in to the design of it. Ask your favourite agent to review the code if you're skeptical.
