Routing Instruction Boundary

Routing Instruction Boundary is a ai policy boundary that separates durable system instructions from user-provided content for selection among models, tools, and workflows. It uses role labels, precedence rules, and prompt assembly checks so teams can avoid instruction confusion while keeping evidence, reliability, and public-safe operational boundaries clear.

“The AI platform team used Routing Instruction Boundary when the router selected a cheaper model, so the team could avoid instruction confusion before the agent workflow reached production.”
