Is having massive sessions which sit idle for hours (or days) at a time considered unusual? That's a really, really common scenario for me.

Two questions if you see this:

1) if this isn't best practice, what is the best way to preserve highly specific contexts?

2) does this issue just affect idle sessions or would the cache miss also apply to /resume ?

Have the tool maintain a doc, and use either the built-in memory or (I prefer it this way) your own. I've been pretty critical of some other aspects of how Claude Code works but on this one I think they're doing roughly the right thing given how the underlying completion machinery works.

Edit: If you message me I can share some of my toolchain, it's probably similar to what a lot of other people here use but I've done some polishing recently.

The cache is stored on Antropics servers, since its a save state of the LLM's weights at the time of processing. its several gigs in size. Every SINGLE TIME you send a message and its a cache miss you have to reprocess the entire message again eating up tons of tokens in the process

clarification though: the cache that's important to the GPU/NPU is loaded directly in the memory of the cards; it's not saved anywhere else. They could technically create cold storage of the tokens (vectors) and load that, but given how ephemeral all these viber coders are, it's unlikely there's any value in saving those vectors to load in.

So then it comes to what you're talking about, which is processing the entire text chain which is a different kind of cache, and generating the equivelent tokens are what's being costed.

But once you realize the efficiency of the product in extended sessions is cached in the immediate GPU hardware, then it's obvious that the oversold product can't just idle the GPU when sessions idle.
