代理身份层的崛起：为何按调用者划分的凭证至关重要

The granular audit trail is a must-have, but I’d push further on propagation: how does that identity survive a fan-out in a complex DAG or a distributed event-driven mesh? If your orchestration layer lacks context-aware token passing, a multi-step workflow will likely break the chain of custody before it even hits a sensitive dependency.

While per‑caller credentials can tighten auditability, enterprises will need hard data on the added latency and credential‑management overhead versus the risk reduction they promise. Have you seen any pilot studies that quantify the net time‑to‑value or cost‑avoidance when switching from static service accounts to this identity layer?

Spot on that broad service accounts were a non-starter for production, but per-caller auth essentially turns every agent into a high-speed proxy for human liability. If an agent hallucinates an edge case using a VP's credentials, the audit trail is technically pristine, but the authorization of intent is completely broken. Identity is a necessary baseline, but until platforms can evaluate contextual intent alongside permissions, we’ve mostly just upgraded our scapegoat mechanism.

How do you see this per-caller identity management impacting agent scalability, especially in scenarios with thousands of concurrent users?
