I suppose there would have to be a capability based model in conjunction with a user oversight model and a time model.
https://en.wikipedia.org/wiki/Capability-based_security
Thus some agents with higher capabilities can only be run with user oversight at the same time.
Some agents can not be run during some part of the day - for example these agents can not run within two hours of office closing time, and cannot run on weekends.
Maybe also the idea of agents writing code - throwing "out fully-fledged programs that you have to approve or reject permissions for."
Would work better with a capabilities based model where you choose capabilities for the program before hand, meaning the capabilities are not written by agent itself, you read through the code, some of it looks hairy but everything is fine, but oh no dumb human missed the part where agent writes to system32! But luckily enough the program you were expecting actually needed no write capabilities and thus when it tries to go past its assigned capabilities that part of the program fails and the exception is registered.
Googling it seems like lots of people have thought this (at least where Capability based security is concerned), which seems reasonable to me as it also seems pretty self-evident it must be this way. Have not really seen anything about time based controls but then that is probably because I'm not devoting a lot of effort as I am just doing a bit of procrastination to build up the energy to finish something off.

A language that revives capabilities, brings them up-to-date, and works in the modern environment is my #1 request from the programming language community right now. I don't need another language with sum types and higher-order functions and a functional focus. I need a language with capabilities. That language may have the other goodies as well, sure, no problem, but we all need capabilities.
I've done some stabby stabs at a design for it, using an AI as the rubber duck. My initial research indicates that the field of "static language that natively supports capabilities" is surprisingly uncovered and there may be a rich field there. E, the closest match, was tied at the hip to Java, which has some advantages but also comes with disadvantages for languages that are trying to do something as exotic as this. Other existing work was on dynamic languages, and hardly rose to the level of "practical for any use" let alone something that could solve our supply chain issues.
My issue is primarily that the reward for successfully designing a language and creating a community around it is that you're in charge of a language community... and, uh, my personality is not suited for that, that sounds more like something I'd pay to avoid then something I'd spend months and years of hard work to attain.
(My advice to anyone doing this is to spend some time with the AI researchers to find the existing work on the topic, not to just sit down and sketch out your initial ideas and run with them. Learn from the past. Expect this to be weeks and probably months of just thinking and noodling before you get to a design. Also, don't try to hook deeply to an existing language, as tempting as it is. This is way too large an impedance mismatch with existing languages. Any external code has to be treated like a nuclear bomb anyhow.)
