Loading initial state

[isterin]

State snapshot event is triggered after the agent is initialized, but what is a method that folks use to get initial agent state before invocation? Do I have to build a custom route for this for every agent? I know ag-ui-adk has an experimental /agents/state route, but this seems like it's specific to adk adapter, and not a standard way of getting initial state to init the client. Any help/ideas would be appreciated. What am I missing?

I my API, I've created a separate endpoint which loads the messages[] stored in the db for a given threadId. i.e. GET /threads/{threadId}. Then, when new events come in for that thread, I process them to update the messages for the thread. So yeah, basically a custom endpoint to get thread history.
