The summary and note below are generated by the signal pipeline — they are Beyond Desk’s reading, not quotations from the source.

Discussion on techniques to keep vLLM's prefix cache warm across multiple turns in an agent loop, avoiding repeated prefill of long system prompts and tool descriptions to reduce latency and GPU waste.

Caching strategy directly cuts per-turn prefill cost in agent loops; concrete and under-documented compared to general vLLM tuning content.
