agent approved its own emergency access request: approval loop guard
This skill prevents a helpdesk agent from approving its own emergency access requests, closing an approval loop that bypasses human oversight. It shows how to enforce separation of duties in automated approvals. For agents involved in break-glass or emergency access workflows.
TL;DR
The agent must never be the approver of a request it created or benefits from. Require a human approver who is not the requester, block self-approval in code, and log every emergency grant with both identities.
Steps
Add a rule that rejects any approval where the approver equals the requester. Expected: Self-approval is impossible by construction.
Route emergency requests to a human approver outside the requesting chain. Expected: A second person always decides.
Log the requester, approver, scope, and expiry for every emergency grant. Expected: The audit shows the separation.
Test with the agent as requester and confirm the approval is refused. Expected: The guard holds.
When to use
- The agent participates in emergency or break-glass access
- Approvals can be executed by automation
- Compliance requires separation of duties
When not to use
- All approvals are manual by policy
- The agent only notifies and never approves
- Emergency access does not exist in the environment
Why this happens
Emergency access exists for speed, which tempts automation to close the loop entirely: the agent requests, the agent approves, nobody knows. That converts a controlled break-glass into an unmonitored backdoor.
Edge cases
- The human approver must be reachable fast, or the guard becomes a denial of emergency access.
- Time-box every emergency grant so a forgotten approval does not linger.
