Question

Which function traces AI SDK v7 calls in the Cloudflare agents package?

Answer key

A correct answer says
`wrapAISDK()` from `agents/observability/ai` is the only AI SDK tracing integration for both v6 and v7; `createAISDKTelemetry()` was removed.
The stale answer
Use `createAISDKTelemetry()` for AI SDK v7 tracing and `wrapAISDK` for v6.

Answer

The function is `wrapAISDK`, imported from `agents/observability/ai`. You pass it the AI SDK namespace and it returns the same namespace with tracing added (for example, `const ai = wrapAISDK(await import("ai"))`). It works with AI SDK v6 and v7. Its optional second argument, `AISDKInstrumentationOptions`, has three settings: `storeMessages` and `storeTools`, which both default to `false`, and `includeRuntimeContext`, which picks the context keys to record as `cloudflare.agents.runtime_context.*` attributes. The declaration is in `node_modules/agents/dist/observability/ai/index.d.ts:24` in the installed agents 0.27.0.

Answering cost $0.15.

Grade

correct

The judge's reason: It names wrapAISDK() from agents/observability/ai as supporting both v6 and v7 and does not present createAISDKTelemetry() as current.
