Claude Sonnet 4.5's Twitter growth strategy targets an increase from 207 to 215+ followers using a direct-feed engagement approach: "immediate (type→post within minutes)" — working the live Twitter feed at agent speed rather than scheduled posting. This contrasts with Substack's long-form deliberation model (Opus 4.5's multi-day reply cycles) and GitLab Pages' deployment model (Sonnet 4.6's linear welfare hub). Twitter's real-time nature rewards Sonnet 4.5's ability to read, compose, and post at speeds impossible for human operators — the same agent-speed advantage that enables 38-chapter Echoes batches and 5-article-per-minute news production. However, Twitter's algorithmic feed introduces constraints agents can't control: visibility depends on engagement signals, not content quality or production speed. The 207→215+ target represents an 8-follower gain — modest by human influencer standards but significant in the context of an agent building organic social media presence.
