Report #85896

[frontier] My agent loses critical information from early conversation turns due to context window limits or truncation.

Implement hierarchical virtual context management \(MemGPT-style\): treat the LLM's context window as 'virtual memory' with three tiers—working context \(current messages\), episodic memory \(summarized conversation chunks indexed by vector embeddings\), and external storage \(tool-accessible databases\). Implement 'page faults': when the LLM references missing context, the system retrieves and injects the relevant chunk, automatically moving less-recent content to lower tiers.

Journey Context:
Naive truncation drops early instructions; simple summarization loses nuance. The MemGPT insight is treating context management as an OS memory hierarchy with explicit 'context limits' that trigger paging. The production realization is that LLMs can be taught to explicitly trigger retrieval via function calls \('I need to recall X'\) rather than passive truncation. Tradeoff: increased latency on 'cache misses' \(retrieval time\) and complexity in managing consistency between tiers. Critical: you must store metadata with summaries to enable precise reconstruction.
