Microsoft describes a layered safety architecture for AI agents that can take production actions, arguing that no single safeguard—model, prompt, or guardrail—is sufficient. The post defines an agent as deterministic software wrapped around a non-deterministic model, and presents four boundaries (identity, tool, mutation, time) that together constrain agent behavior. It emphasizes that authorization, not intelligence, is the hard part of safe autonomy.

## Evidence

Verbatim from https://commandline.microsoft.com/ai-agent-copilot-autopilot-layered-model-production-network-incidents-on-call-engineers/:

> There is no single thing you can build that makes an agent safe to run in production. Not a smarter model, not a stricter prompt, not a clever guardrail. Safe autonomy requires a stack.
