this is insane! Why on earth would one to replace a short, simple, highly debugable program with this crazy combination. Why would you trade a simple socket(2) call which shows up in ss, netstat, strace etc.. with something that opaque? Especially given the bandwidth is minuscule and the destination is already localhost.

Your past experience limits your thinking, especially in agentic environments.
But I suppose their whole business model is built upon that, given that yeet is a bun/node/deno library with bpf support.

we embed V8 directly and just point it at bpf

it has some really nice properties for dynamically instrumenting the OS.
and provides lightweight isolation for agents to control probes and do deep packet analysis.
