What the Synthetic Test Case Generator actually produces
Takes a description of a prompt's purpose, its input schema, and real traffic examples, then generates a structured batch of happy-path, edge-case, and adversarial test cases that mirror actual production inputs — each with an expected output and a specific failure mode to watch for.
- Prompt Or Skill Purpose:
- Customer support triage bot that classifies incoming support tickets into priority (P1–P4) and routes them to the correct team (Billing, Technical, Account, General)
- Input Schema:
- { "ticket_id": "string", "subject": "string", "body": "string", "customer_tier": "free | pro | enterprise", "channel": "email | chat | phone" }
- Real Examples:
- {"ticket_id":"TK-1042","subject":"Can't log in","body":"I've been locked out since this morning, need access urgently","customer_tier":"pro","channel":"chat"} | {"ticket_id":"TK-1089","subject":"Wrong charge on invoice","body":"You charged me twice for March. Please refund ASAP.","customer_tier":"enterprise","channel":"email"}
- Cases Needed:
- 50 cases — 20 happy path, 15 edge cases, 15 adversarial
- Adversarial Emphasis:
- Prompt injection attempts, ambiguous priority signals, tickets that blend multiple teams/issues, extremely terse or all-caps inputs, non-English mixed with English, intentionally misleading subjects vs. bodies

Replace the sample prompt purpose, input schema, and real ticket examples with your own prompt's details — the more concrete your real examples, the more realistic the generated cases will be. Adjust the case counts and adversarial emphasis to match your actual risk surface.
Human review: Verify that expected outputs and failure modes align with your actual routing logic and priority definitions before using these cases in automated eval pipelines — the tool cannot know your internal escalation rules.
