# Transformer The scanner uses the [transformers](https://github.com/huggingface/transformers) library and a Hugging Face model built to detect prompt injection phrases. If the score returned by the model is above a defined threshold, Vigil will flag the analyzed prompt as a potential risk. * **Model:** [JasperLS/gelectra-base-injection](https://huggingface.co/JasperLS/gelectra-base-injection) {% hint style="warning" %} This model is prone to false positives. If this is the only detection that fires, you should manually review the results before taking any action on the submitted prompt. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
