Report #92294

[frontier] Long-context agents burn tokens re-sending static system prompts and documents every turn

Implement prompt caching \(Anthropic\) or context caching \(Gemini\) to persist long documents across turns at 90% reduced cost, enabling economic long-horizon agents

Journey Context:
Re-sending 100k\+ tokens per turn makes long agents uneconomical; caching static prefixes allows agents to maintain long context affordably. This replaces naive RAG for known documents with guaranteed context availability
