One of the things that has Claude as my goto option is its ability to start long-running processes, which it can read the output of to debug things.

There are a bunch of hacks you could have used here to skip the manual part, like piping dmesg to a local udp port and having Claude start a listener.

I think that's the thing holding a lot of coders back on agentic coding, these little tricks are still hard to get working. And that feedback loop is so important.

Even something simple like getting it to run a dev server in react can have it opening multiple servers and getting confused. I've watched streams where the programmer is constantly telling it to use an already running server.
