Report #77981

[frontier] Agent context windows overflowing, losing critical early-session instructions while retaining irrelevant fluff

Implement a three-tier memory system: \(1\) Working Context \(current conversation, in-window\), \(2\) Short-term Memory \(recent summaries, retrieved via RAG\), \(3\) Long-term Memory \(user profile, facts, in vector DB\); use an 'attention gate' to decide what gets promoted/demoted between tiers

Journey Context:
Naive RAG treats all history equally. Humans have working memory vs long-term. Agents need similar hierarchy. The 'MemGPT' insight: use the LLM itself to manage memory via explicit function calls \(page in/out\). Mistake: just truncating old messages \(loses key facts\). Alternative: summarization only \(loses granularity\). Tiered approach with explicit memory management functions.
