There appears to be a severe regression in the Claude Code CLI that makes it nearly impossible to use for extended sessions right now. Since the weekend, premium quotas are being drained in 10 to 15 minutes. According to GitHub issue, the CLI is instantly hitting rate limits even with extremely high cache hit rates (98%+). A single workflow goes from 0 to 100% quota usage almost immediately. For a tool that costs 100+ dollars per month for these higher limits, getting locked out after two prompts is incredibly frustrating. Cant say if this is a temporary bug, or a taste of things to come.
