logs reads the deployed agent’s lines from both the function and the actor, one per line, with the time, the source, fn or actor, and the level:
toolCall, voiceWake, voiceCall, voiceTurn and modelStream among them, so grep picks one out. --type invocations lists the requests that reached the function and the actor, with the method, the path, the status, the milliseconds and the region; a request on an RPC path is shown as the conversation and the method:
--tail streams the function’s lines only, where reading history includes the actor’s too. It has no --json form.
