Made the case for a single source of truth
In "Don't Build Multi-Agents" Yan showed that parallel agents quietly diverge because every action carries an implicit decision the others never see — his single-writer principle insists shared context be one durable thing, written down, not re-implied in each agent's head. An early, influential proponent of context engineering, arguing from inside a frontier coding lab the move Tropo makes: decisions belong in the substrate.
