[frontier] How to manage context window limits when agents need to maintain long-term conversational and procedural memory?

Implement an explicit tiered memory hierarchy \(main context, recall storage, archival storage\) with an LLM-driven 'memory manager' that handles page-fault-like retrieval and compaction.

Journey Context:
Simple RAG or summarization fails for complex agent tasks requiring precise tool call history and evolving user preferences. MemGPT treats the LLM context window like an OS memory hierarchy: limited 'main context' \(RAM\), larger 'recall storage' \(SSD\) for recent facts, and 'archival storage' \(Disk\) for old data. A separate 'memory manager' LLM monitors context pressure and triggers 'page faults' \(retrieval\) or 'compaction' \(summarization\). This allows agents to maintain effectively infinite context while preserving exact tool schemas and critical conversation history. Tradeoff: Requires careful tuning of memory manager prompts to avoid retrieval loops.
