This breaks Zero Trust principles, loses context and delegation information, and opens the door to rogue agents chaining tools without authorization. The proposed solutions include implementing ABAC/PBAC policies on backend systems, introducing a vault as an abstraction layer to validate identity, context, and delegation while issuing short-lived credentials, and collecting telemetry to continuously refine and restrict permissions. ## Full article daily.dev links to this article rather than hosting it.
