The Quadratic Loop Trap

Every conversational turn resends all prior user queries, model responses, and bulky MCP tool outputs. Without sliding compaction, a 20-turn agent session re-reads tens of thousands of redundant tokens on every call.

Prefix Prompt Caching

Anthropic, OpenAI, and DeepSeek cache static prefixes at up to 90% discount. Storing system instructions and tool schemas identically at the beginning of each payload dramatically slashes operational costs.
