> Adding an in-product tip to recommend running /clear when re-visiting old conversations (we shipped a few iterations of this)

I feel like I'm missing something here. Why would I revisit an old conversation only to clear it?

To me it sounds like a prompt-cache miss for a big context absolutely needs to be a per-instance warning and confirmation. Or even better a live status indicating what sending a message will cost you in terms of input tokens.
