Hi Nauyan! That's a great question. there's 2 parts to this question

1. can the cosine similarity value be isolated and logged
2. Is there a good way to pass additional information back out of completed validator checks - in this specific instance, we want to pass teh cosine similarity value back out of the validator

my thoughts:

1. absolutely. If you have guardrails installed locally, you can add a print statement before this line - print(most_similar_chunk[1])
2. kind of but it's ugly. There is a metadata field as part of the ValidationResult class (from which PassResult and FailResult inherit). This does make its way through to the validation object in the guard's history. The access pattern is a little deep though, I left a snippet below, take a look at the very last line (you can run it as well). Provenance doesn't currently keep those values in metadata, but I think it's a good idea to add that! I'll open an issue here - [feat] Provenance - Add metadata with underlying numbers to the PassResult and FailResult #575
