Could you build this?
Yes It is a simple utility script or daemon that periodically pings or sends keep-alive tokens to a Claude CLI session or Anthropic API prompt cache to prevent timeout.
Discussion
20 comments analyzed.
Competitors mentioned: DeepSeek API, OpenAI (prompt caching)
Concerns raised: VRAM reservation costs and economics unsustainable long-term, Cache miss penalty: 10x more expensive for uncached tokens after 5 minutes, Anthropic will need to charge for VRAM or raise prices for other customers, 5-minute cache timeout appears arbitrary and affects shared resource availability, Below 100k context, cache reads more expensive than redoing prefill
Feature requests: Extend cache timeout beyond 5 minutes with pay-per-minute VRAM reservation model, Subscription-based cache retention option with renewal periods
