AI agent permissions: treat access as an operating design decision

An agent becomes operationally significant when it can take actions, access sensitive information or influence other systems. Permissions determine the size of that operating surface.

Start with least privilege

Give the system only the tools, data and actions required for the current use case. A customer-support agent may need order status but not payroll records. A research agent may need read access without the ability to publish or purchase.

Separate read, recommend and write authority

Reading data, suggesting an action and executing an action are materially different capabilities. Treat them as separate permissions rather than one broad access decision.

Bound irreversible actions

Payments, external communications, data deletion, permission changes and commitments to customers deserve stronger controls because mistakes are costly or hard to reverse.

Keep an attributable trail

Important actions should be attributable to an agent identity, owner, tool, time and purpose. Logs matter most when they support investigation and response rather than existing only for compliance theater.

Specific legal, security and regulatory requirements vary by organization and jurisdiction; this material is general educational guidance.
