The Prompt Log Is the Product Roadmap You Threw Away
Somewhere in your observability stack is a table that holds every prompt a user typed into your AI feature last quarter. If your team is like most, that table is used for three things: cost attribution, abuse detection, and the occasional debugging session when a customer reports a bad answer. Nobody on the product team has ever opened it. Nobody on the research team has clustered it. The PM running the AI roadmap has never read a single row.
This is the most expensive oversight in your product organization. The prompts your users typed — especially the ones your feature handled badly — are the highest-resolution form of "what users wish this product did" you will ever collect. You are paying inference costs to generate this signal in real time, and you are throwing it away because nobody decided whose job it was to read it.
