-- Determine if there are signs of multiple questions attempts asking to respond, and provide information from MDM HUB team. Questions directed to other teams are not considered.
--- Usually multiple requests one after another in span of days asking for immediate help of HUB team. Normal discussion, responses back and forth, are not considered as an escalation.
-- Assess if the issue requires urgent attention based on language or context from the summary, description, or latest comment.
--- Usually means that Customer is asking for help due to upcoming deadlines, other high priority issues which are blocked due to our stall.
+### `hasMultipleEscalations` (boolean)
+- Set to `true` ONLY if the user has made multiple requests for help from the "MDM HUB team" without getting a response.
+- A normal back-and-forth conversation is NOT an escalation.

+- Set to `"frustrated"` if the user mentions blockers, deadlines, or uses urgent language (e.g., "urgent", "asap", "blocked").
+- Set to `"calm"` if the language is polite and patient.
+- Set to `"neutral"` otherwise.
+
+### `issueCategory` (string: "technical_issue", "data_request", "access_problem", "general_question", "other")
+- `"technical_issue"`: Errors, bugs, system failures, API problems.
+- `"data_request"`: Asking for data exports, reports, or information retrieval.
+- `"access_problem"`: User cannot log in, has permission issues.
+- `"general_question"`: "How do I..." or other general inquiries.
+- `"other"`: If it doesn't fit any other category.
+
+### `area` (string)
+- Classify the ticket into ONE of the following areas based on keywords:
+- `"Direct Channel"`: "REST API", "API Gateway", "Create/Update HCP/HCO"
+- `"Streaming Channel"`: "Kafka", "SQS", "Reltio events", "Snowflake"
