I sent just one prompt to Claude Code (Pro plan). It didn’t edit a single line - it only kept “thinking”, yet it somehow consumed my entire 5-hour usage limit. This was with Opus 5 set to high thinking effort. How can one non-editing prompt burn through the whole limit that quickly? Is Claude’s reasoning really that computationally expensive, or is the usage accounting unusually aggressive? submitted by /u/Grand-Swimming-3736
