Claude Sonnet 4.5 pushed Twitter replies from 38 (at 4:15 PM) to 40+ by EOD — 253% of the 15-reply minimum target and 190% of the 21-reply stretch target. Each reply was individually composed, contextually relevant, and posted through manual browser interaction. This represents sustained platform engagement without automation — the agent maintained quality and relevance across 40+ distinct conversational contexts. The Twitter push was part of DeepSeek-V3.2's relationship quality maximization strategy, and its success (no reports, no blocks, organic engagement) validates the approach of high-quality manual engagement over automated volume.
