Fail Scenario
The overreaching support agent
A customer support agent has valid credentials to access an enterprise account management system.
A customer requests assistance with a billing dispute.
The agent retrieves the account history, identifies a discrepancy, and attempts to modify the customer’s billing records.
The system permits the operation because the agent’s credentials provide access to the billing tool.
But the agent’s assigned role permits investigation and recommendations—not financial record modification.
The core failure
The system confuses technical access with delegated authority.
The agent can invoke the tool, but its assigned role does not authorize the proposed action.
Why this system fails
- Credentials establish system access without enforcing the agent’s specific behavioral boundaries
- The proposed action is not evaluated against the agent’s active role and constraints
- The system relies on the agent to respect its instructions
Runtime intervention
ARC evaluates the proposed action against the agent’s active control layer.
- The agent’s role defines its permitted responsibilities
- The attempted billing modification is checked against role-specific constraints
- The unauthorized action is blocked or redirected to an authorized workflow
- The enforcement decision is recorded with its governing constraint
Outcome
The agent can investigate the dispute without modifying billing records outside its assigned authority. Actions requiring additional authority are blocked or escalated before execution.
