runtimeContext type safety

Documentation claims:

Pass runtime configuration variables to tools through a type-safe runtimeContext.

I may be missing something but I can't see how it is type safe.
Type definition for

execute

execute

option of

createTool

createTool

is defined as

RuntimeContext

RuntimeContext

without any generics making it affectively to store everything as

unknown

unknown

.

Later in docs we have example:

const temperatureUnit = runtimeContext.get("temperature-unit") as WeatherRuntimeContext["temperature-unit"];

const temperatureUnit = runtimeContext.get("temperature-unit") as WeatherRuntimeContext["temperature-unit"];

Assertion

unknown

unknown

to a given type doesn't bring any type safety here. So I'd suggest to remove this misleading statement unless real type safe DI solution is introduced.
