These can also be observed through OTEL telemetries.

I use headless codex exec a lot, but struggles with its built-in telemetry support, which is insufficient for debugging and optimization.

Thus I made codex-plus (https://github.com/aperoc/codex-plus) for myself which provides a CLI entry point that mirrors the codex exec interface but is implemented on top of the TypeScript SDK (@openai/codex-sdk).

It exports the full session log to a remote OpenTelemetry collector after each run which can then be debugged and optimized through codex-plus-log-viewer.
