do you know of a mitm proxy that "just works"? meaning, is able to spoof/intercept/modify running processes well enough that most stuff would run without manual modification?
There are tons that are all too simple or too complex or made for mesh networking in k8, or too slow and made for debugging. My go-to solution is to make ad-hoc proxies with workerd that work just the way i need and compile to a "binary". It used to be annoying to write capnp by hand but now you just point an agent at worker.capnp and tell it what you need. The output is concise enough to be nice for proper reviewing and as extendable starting point, so neither vibe coding nor much manual coding needed.
