the session gave me the new usage limit / command thing, i selected the first option then sent a new message, it kept working but keeps printing the usage limit command between messages and tool calls
eventually i stoped it then tried again it didnt work, then i exited the session and tried to start a new session with cladude command but i got this error
What Should Happen?
it should ether tell me that the rate limits are exceeded or start a new chat
