Agent Security
What makes an agent access policy maintainable over time?

An agent access policy is maintainable when it is explicit, reviewable, scoped to roles or workloads, and not scattered across application code. Policies should map agents to allowed tools and operations, with clear ownership for approvals and changes. They should also support environments, data sensitivity, and operational context without becoming impossible to reason about. Logging denied and allowed actions helps teams see whether the policy still matches reality. Diagrid's approach favors identity-based access control and policy at the platform layer, so teams can adjust governance without rewriting each agent implementation.
