+1 having something something analogous to what nodes take since this was how it was with config before v0.6

def node(state: State, runtime: Runtime[Context]):
    # type safe access to context attributes    
    user_id = runtime.context.user_id
    db_conn = runtime.context.db_connection
    ...

# should also  be valid
def some_tool(runtime: Runtime[Context]):
    ...
