[architecture] Agent stores too much conversational detail and important signals are lost in noise at retrieval time

Apply aggressive compression on the write path: extract atomic, self-contained facts before storing. Each memory should be a single assertion. Never store raw conversation turns in the memory index—run a summarization extraction pass first. If you need audit trails, store raw logs in a separate system, not in the retrieval index.

Journey Context:
The instinct is to store verbatim conversation because 'the LLM can figure out what is important later.' But this is the garbage-in-garbage-out problem of memory systems. Raw conversations contain hedging, repetition, social niceties, and context that is only meaningful in the moment. When retrieved later, they waste context window space and dilute the signal with noise. The failed alternative is storing nothing and relying purely on the current context, which loses cross-session learning. The correct pattern is extract-then-store: after each meaningful interaction, run a summarization pass that extracts atomic facts \('User prefers TypeScript over JavaScript for new projects' not 'well I guess I have been leaning towards typescript lately for new stuff'\). This costs an extra LLM call per interaction but dramatically improves retrieval precision because the embedding of a clean atomic fact has much higher signal-to-noise ratio than the embedding of a rambling conversation turn. The tradeoff: you lose the ability to reconstruct exactly what was said, and the extraction step can introduce summarization errors. For most agent use cases, this is the right trade. The Generative Agents paper validated this approach by showing that extracted, scored memories produce far better agent behavior than raw logs. If you need verbatim records for compliance or debugging, store them in a separate append-only log—do not put them in the vector index that powers retrieval.
