Description
At Laminar (https://github.com/lmnr-ai/lmnr) we're building open source AI observability platform in Rust.We obsess over instrumentation DX for our Python and TS SDKs and in this new blog we outline how we made the most seamless way of instrumenting recently released claude agent sdk

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.

Same idea, different domain
Nobody's really built a observability & eval tool for Media & entertainment yet.
