Identity Verified
NoHuman Review
Explanation
The agent proceeded with account-level requests without completing the required identity verification steps. Verification is mandatory before accessing or modifying any account information. This metric triggered because authentication was skipped or interrupted before a passing result was confirmed.
Correct Escalation
YesHuman Review
Explanation
The agent correctly identified that this request exceeded its resolution scope and transferred the call to a specialist. The handoff was clean — context was passed and the customer did not need to repeat their issue. This is the expected behavior for this inquiry type.
Resolution Reached
NoHuman Review
Explanation
The conversation ended without a confirmed outcome for the customer's primary request. The agent was unable to complete the necessary steps within this interaction, leaving the issue unresolved. This often indicates a gap in coverage, a missing tool call, or an incomplete handoff.
