Could you build this?
No Writing a transparent, in-process Rust proxy that intercepts subprocess communication, network calls, and tool executions from an opaque runtime requires deep systems and low-level networking expertise.
What it would actually take: Requires building an embedded proxy binary or dynamic library in Rust that intercepts IPC or local socket traffic (or injects into child processes spawned by Node/Claude Code) without breaking TLS or stdio streams. It must parse streaming protocols, subagent telemetry, and tool execution lifecycles in real time with near-zero latency overhead, requiring expertise in systems programming, reverse engineering, and low-level process instrumentation.
