# Prompt: read a COA photo into fields

Attach the photo, then paste this. Change the keys to the fields your state and your label require.

```
Read this certificate of analysis photo. Return JSON only with keys: sample, batch, report_date, thca_pct, d9_thc_pct, total_thc_pct, total_cbd_pct, yeast_mold, overall_result.
Copy values exactly as printed. If a value is not clearly legible, use "UNREADABLE". Never guess or calculate a value that you cannot read.
```

The last two sentences are the point. In our test on a blurry photo with glare, the same request without them came back with confident, wrong numbers (THCa 24.91 for a printed 24.81, total CBD 0.41 for a printed 0.05) and the wrong year. With them, it said UNREADABLE for exactly the fields that were washed out.

Then run `check.py` on the result. Never paste the AI's numbers into a label, a menu or Metrc without that check and a person looking at the flags.
