Three teams shipped the same fix for AI agents losing cross-repo context

Three independent teams (Neilos, Mabl, Meta) recently published similar diagnoses and solutions for AI coding agents losing cross-repo context. They found that agents make locally correct changes that break consumers in other repositories due to lack of a global dependency graph. Mabl and Meta built queryable dependency graphs, while Neilos used a manager agent for coordination. The article argues that cross-repo dependency graphs should be an infrastructure primitive rather than rebuilt by every team. Riftmap provides such an API.
