Could you build this?
Partial While the desktop UI and cost calculations are easily vibe-coded, building a reliable local MITM HTTPS proxy with dynamic root CA generation and streaming SSE protocol parsers requires systems networking expertise.
What it would actually take: The core requires a local proxy daemon in Rust or Go utilizing custom TLS certificate generation and installation into system trust stores to intercept HTTPS traffic. The hard part is multiplexing streaming HTTP/2 and Server-Sent Events (SSE) connections from various coding agents with near-zero latency while dynamically parsing token usage chunks and cache-hit headers without corrupting the stream.
