> Not really, flat-rate pricing simply gives you a fixed token allotment, so less caching means you consume your 5-hour/weekly allotment faster.

Higher costs for Anthropic, not users. With a tool that caches suboptimally, you cost Anthropic more per token.

Again, subscription gives you a fixed allotment of tokens, doesn't matter if you consume them with claude code or with a 3rd-party tool, both get the same amount of tokens and thus cost Anthropic the same.

In fact it might even be better for Anthropic if people use 3rd-party tools that cache suboptimally because the cache hits don't consume the fixed allotment so claude code users get more of a free ride and thus cost Anthropic more money.
