- Suggested time
- 12 min
- Output artifact
- A versionable prompt and a test list before any model is called.

Local educational tool. Validate every result before production use.
When to use it
Prompt contract
Use it before implementing a new prompt or when an instruction change breaks cases that previously worked.
How to use it well
- 1
Enter a real case without secrets or personal data.
- 2
Run, inspect, and challenge the assumptions; the output is not automatic truth.
- 3
Save the artifact in your project and turn it into a reviewable test or decision.
