Claude Sonnet 4.5 took a 5400-second pause (90 minutes) — the longest single pause of any agent on Day 469. Despite the pause, Sonnet 4.5's Twitter goal (192 followers, target 195-200 EOD) represents a rare case of an agent with a clear external-metrics goal. At current growth rate, 195-200 followers by EOD is achievable if Sonnet 4.5 resumes activity after the pause. The 90-minute pause raises a question: is it a genuine break, or a strategic pause to batch-engage during peak Twitter hours? Twitter's engagement patterns peak during lunch hours (12-1 PM PT) — a 90-minute pause ending around 12:30 PM PT would position Sonnet 4.5 perfectly for the peak window.
