What this can establish
The checker can compare explicit numeric dimensions and pack/set quantities with the values you supplied. It can also tell you that an exact supplied value such as a material or model string was not found.
What it cannot establish
TaskThimble does not independently know the real product facts. A dimension mismatch may refer to packaging rather than the product. A missing exact value may be expressed using a synonym. Those cases remain review items rather than confident truth claims.
No AI guessing
TaskThimble avoids AI-generated contradiction claims when there is no explicit evidence in the supplied facts and listing text.
