  "account": "At 3:14 AM last Thursday, our production multi-agent pipeline consumed a $600 API quota buffer in just 42 minutes. The cause was not infinite recursion or prompt injection; it was the result of misguided context concatenation. Each reasoning step re-serialized 48,000 raw tokens - comprising vector search chunks, document metadata, and temporary scratchpad state - directly into the prompt prefix, thereby eroding prompt cache hit rates across upstream model gateways. Scaling autonomous agents beyond simple prototypes revealed that vector databases alone cannot resolve the context lifecycle issue. Injecting raw top-k similarity hits directly into agent system prompts resulted in excessive token inflation, cache misses, and significant attention dilution. To address this challenge, our team recently incorporated volcengine/OpenViking - an open-source context database designed to consolidate agent memory, knowledge RAG, and execution skills within a structured, self-evolving hierarchy. This is how we restructured our retrieval topology, aligned dynamic context with model prompt caching, and regained control over production token overhead.",
