We do end up doing a GPT based rewrite. The initial description is really valuable too though, and we want to keep that throughout the workflow. It's kind of similar to a spelling correction or query intent system. If it's high confidence you can override their query, but ideally you use the original one too.

I didn't mention this point, but we actually do that during the modification. We ask the LLM to extract the necessary subcontext from the main context. It doesn't increase the costs much, but it does help performance because the unnecessary context is stripped away.
