[bot] Instrument Portkey AI (140,424 weekly downloads)

Inizia leggendo le configurazioni esistenti di auto-instrumentation di openrouter e ai-sdk, il registro in js/src/auto-instrumentations/configs/all.ts e gli scenari in e2e/scenarios/. Confronta questi pattern con i sorgenti dell’SDK portkey-ai e con le relative API del client Portkey e di chat completions. Il lavoro è completo quando le chiamate di generazione e streaming di Portkey sono instrumentate e coperte da uno scenario end-to-end.

Summary

Portkey AI's official Node.js SDK (portkey-ai) is a drop-in, OpenAI-SDK-shaped client (portkey.chat.completions.create(...)) that routes generation calls through Portkey's gateway to 250+ LLMs, with its own prompt-management and completion-execution surface distinct from the underlying provider SDKs. This execution surface is not instrumented anywhere in this repository.

What's missing

• new Portkey({...}) client construction and portkey.chat.completions.create(...) (and streaming variants) — the SDK's primary generation-execution API — has no auto-instrumentation config, wrapper, or e2e scenario in this repo.
• None of portkey-ai, Portkey, or PORTKEY_GATEWAY_URL appear anywhere in js/src/, js/src/auto-instrumentations/configs/all.ts, or any e2e/scenarios/* directory. (This is distinct from the already-instrumented openrouter/ai-sdk gateway-style configs, which target different packages.)

Braintrust docs status

unclear — Braintrust publishes a comparison article, "Braintrust vs Portkey" (https://www.braintrust.dev/articles/braintrust-vs-portkey), describing a pattern where Portkey stays in the request path for routing/guardrails while traces are sent to Braintrust "through its SDK or OpenTelemetry integration" — but this describes manual OTel/generic tracing, not a dedicated auto-instrumentation wrapper for the portkey-ai package. Portkey does not appear in Braintrust's main integrations catalog at https://www.braintrust.dev/docs/integrations (full grid enumerated in the companion E2B gap issue).
