They postponed that change, here is the email they sent out:
> In May, we sent you an email announcing that starting today, the Claude Agent SDK, claude -p, and third-party apps built on the Agent SDK would stop drawing from subscription rate limits and move to a dedicated monthly credit. We're writing to let you know that we’re not making this change today. We’re working to update the plan to better support how users build with Claude subscriptions.
> What this means for you
> Nothing changes for now. Agent SDK, claude -p, and third-party app usage continues to work with your subscription exactly as it did before today, and there's no credit to claim. Your subscription limits are unchanged. When we have an update, we'll share it with advance notice before it takes effect
Something I haven't been able to figure out.... How are you supposed to actually get an API key to use quota from your subscription? The terms of service still forbid using OAuth authentication and the API keys from the console indicate that you need to pre-load your account with funds when you try to use them.
