Hopefully they never actually implement this pointless feature because it will only give people a false sense of security given the unpredictable nature of LLMs. How could something like this even be enforced?

People just need to learn how to use the tools their system already provides them. i.e., chmod

The whole point of using an agent is that I don't want to learn everything. I fully expected the harness to read the .agentignore file and do what is needed to hide it from the LLM.

But apparently, even if implemented, that's not how it works!
