Where this workflow helps

Common friction

  • reviewers disagree on what is unusual
  • raw anomalies lack context
  • manual notes are inconsistent
  • causes are guessed too quickly

Repeatable process

  1. Provide normal examples and suspicious examples.
  2. Ask AI to describe the difference.
  3. Require severity and next-check fields.
  4. Keep causes as assumptions unless verified.

Reusable prompts

Open prompt pack

Create a before-and-after anomaly review from these normal and suspicious rows.

Explain what changed, why it was flagged, and what should be checked next.

Rank these anomalies by review priority without inventing causes.
