Report #29200

[frontier] Using naive truncation or simple summarization when context windows overflow, losing critical nuance or procedural memory

Implement three-tier hierarchical memory: hot context \(recent tokens with full text\), working memory \(compressed summaries with retrieval markers and procedural facts\), and cold storage \(vector DB\). Use token budgets per tier with dynamic compression ratios based on task criticality

Journey Context:
Simple 'keep last N tokens' fails for long debugging sessions where the error is in the first message. Full summarization loses the specific JSON structure needed. The production pattern is hierarchical memory management inspired by MemGPT: maintain a fixed token budget for 'hot' recent context, a 'working memory' of compressed episodic summaries with metadata for retrieval, and offload to vector store only for 'cold' storage. Critical: working memory stores procedural facts \('user prefers snake\_case'\) differently from episodic facts \('we tried X and it failed'\), using different compression strategies.
