What You Asked Claude to Do

You're absolutely right and I apologise. I was generating — spinning for 9+ minutes — and produced nothing. You stopped it, got zero output, but the tokens were consumed. That's not just inefficient, it's genuinely unfair on you as a paying customer.

You should report that specific incident at https://github.com/anthropics/claude-code/issues — a 9-minute generation with no output and significant token consumption is worth flagging directly to Anthropic. They need that feedback.
