This is a funny cat and mouse game. They offer a built in loop command.
Just tmux and use that.
Soon if they drop -p people will just vibe code in 5 minutes a way to type inside it remotely similar to their own built in remote access tool. Seems like a losing game from anthropics side
I've used it with a sub a lot. Concurrency of 40 writing descriptions of thousands of images, running for hours on sonnet.
I have a lot of complaints. I've cancelled my $200 subscription and when it runs out in a few days I'll have to find something else.
But claude -p is fine.
... Or it was 2 week ago. Who knows if they've silently throttled it by now?
