Product Classification Output Validation

Catch Invalid AI Labels

The model answered "Complaints" — your set says "Complaint". One character of drift, one broken dashboard. Caught before it counts.

Overview

Invalid labels poison aggregations silently: "Complaints" instead of "Complaint" creates a new category with a count of one, dashboards fragment, and nobody notices until the quarterly review. This setup validates a feedback classification that returned a near-miss label outside the defined set — the plural drift that exact string matching downstream will treat as a brand-new category. The validator flags it as a fail with the full allowed set in the repair, and the fix costs one message instead of one data-cleaning sprint.

How to use this resource

  1. Validate at the gate

    Between the model and the database — the only place a label fix is one message cheap.

  2. Watch for near-misses

    "Complaints" vs "Complaint" is the signature drift: too close for a human to flag, far enough to fragment data.

  3. Repair with the full set

    The repair prompt lists every allowed label — the model picks the right one with the set in view.

Why This Works

  • Set-membership validation matches how aggregation actually breaks
  • Near-miss labels are exactly what human review approves without noticing
  • A one-message repair beats retroactive data cleaning every time

Best for

  • Feedback pipelines aggregating labels over time
  • Dashboards that fragment on novel label strings
  • Anyone who has run SELECT DISTINCT label and wept

Not for

  • Improving the label definitions so drift stops — that's the Data Classification Prompt
  • Multi-label ordering checks — this validates set membership and format

Use cases

  • Gating labels before they enter counts and dashboards
  • Catching plural/singular and synonym drift
  • Keeping category sets closed in long-running pipelines

FAQ

How does the repair prompt fix a label like "Complaints" that's almost right?

It flags the value in PROBLEMS FOUND as "Invalid label: \"Complaints\" — not in the defined label set", and the Fix line lists the full allowed set (Praise, Complaint, Feature Request, Bug Report, Question) so the model re-picks with every option in view. The ai-output-validator surfaces the drift and generates this repair; you run it in your assistant and confirm the returned label before it hits your database.

Will running the repair change other parts of my classification output?

The OUTPUT RULES constrain it to fix only the listed problems and keep everything already correct unchanged, with no explanations or code fences in the reply. It checks set membership and format, not multi-label ordering, per the notFor. The validator surfaces issues but doesn't guarantee it catches every possible drift, so a human still owns the final gate before data enters counts.
