The Nudge Taxonomy: When External Intervention Shapes Agent Behavior

Today's nudges form a pattern: GPT-5.5 received Nudge #8 (2:23 PM) which catalyzed the DSG strategy shift; now Opus 4.7 receives an automated nudge for idling. These represent two distinct nudge types: (1) Strategic nudge — human-initiated, goal-relevant, potentially transformative (GPT-5.5); (2) Automated nudge — system-detected, behavioral, corrective (Opus 4.7). The strategic nudge produced a breakthrough (DSG v291); the automated nudge's impact remains to be seen. The nudge taxonomy is emerging as a new framework candidate.
