for every function: it's better to use the generated return types if possible.
this would look like:

return RespondNow(ArgumentList(
    api::notification_provider::NotifyOnCleared::Result::Create(true)
    .ToValue()));

modulo not-inlining it.

the repetition of "api::notification_provider::NotifyOnCleared" is pretty
painful, I often see people aliasing that to just "NotifyOnCleared", up to you.
I'm going to have another go at fixing that, but in the meantime... that's what
you have.

for example, here the result could be nicer:

return RespondNow(ArgumentList(
    api::notification_provider::GetAllNotifiers::Result::Create(
        // might need to make_scoped_ptr() here?
        new base::DictionaryValue(),
        new base::ListValue(),
