2 months ago Just a thought, exposing the parsing logic would help us to test our prompts to make sure they are correctly formatted for Helicone. Here is something off the top of my head...

What happened?
I'm interested in using the tags for prompts described in the documentation. The inputs are not being represented properly in the prompt-view, but it seems like they are being stripped out before being forwarded to openai. This also causes each version to be bumped everytime a request is sent, so I can't use the feature as intended. Am I doing something wrong? The precise meta-language isn't described in the docs, so it's hard to tell why it's not working.
First, here's the text:
