The official documentation on context engineering includes the following code. Does this return a value that updates the runtime’s state object?

The official documentation on context engineering includes the following code. Does this return a value that updates the runtime’s state object?

@tool
def authenticate_user(
password: str,
runtime: ToolRuntime

) → Command:

““Authenticate user and update State.””"

#Perform authentication (simplified)

if password == “correct”:

#Write to State: mark as authenticated using Command

return Command(
update={“authenticated”: True},

)
else:

return Command(update={“authenticated”: False})

Hi,

Yes - this creates an update to the state! For more information, see docs here.
