[frontier] Agent loses critical state after long-running task due to context window overflow
Implement hierarchical memory checkpointing: compress older conversation turns into structured 'memory anchors' \(semantic triples \+ summaries\) stored in a vector DB, retrieved via similarity search when needed, rather than using naive sliding window truncation.
Journey Context:
Naive truncation drops system instructions or user constraints. Simple summarization loses nuanced causality. The emerging pattern is a tiered approach: recent turns kept verbatim, mid-term turns compressed into structured 'facts' \(subject-predicate-object\), and long-term episodic memory summarized with embeddings. This preserves the causal chain for reasoning while fitting physical context limits. Mem0 and similar architectures prove this beats raw RAG for conversation state.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
