Schema-Enforced Ticket Triage with Mistral Structured Output

id: mistral-structured-ticket-triage
namespace: company.team
description: |
  Triage a support ticket with a Mistral chat completion whose output is
  locked to a JSON schema, parse the category and severity into scalar
  outputs, and page Discord only when the severity is high.

inputs:
  - id: ticket_text
    type: STRING
    defaults: Our production dashboard has been returning 500 errors since this
      morning. None of our team can access order data and customers are calling
      in.
    description: Raw support ticket text to triage. The model never controls the
      output shape, only the field values.

  - id: model_name
    type: STRING
    defaults: mistral-small-latest
    description: Mistral model identifier used for triage. Larger models help with
      ambiguous or multilingual tickets.

  - id: triage

    description: Classify the ticket with a JSON schema enforced response, so the
      output is always a valid object with category, severity, and summary and
      prompt content cannot inject extra fields.
