Agent Context Architecture Standardizes

Reliability on long-horizon agent tasks is increasingly determined by how context is partitioned rather than by model capability, so expect recurring architectural conventions, contracts and registry requirements to form around context isolation.

Strengthened +6
A Cornell and Microsoft Research paper finds agent skills perform better dispatched to subagents with fresh context windows than injected into a growing main context, conditional on skills exposing clear input-output contracts. Peer-level research identifying the input-output contract as the enabling condition is the move from folklore to a stated architectural convention.
