Structured Agent Memory

Store tables, queues, and other structured state outside raw prompt text so the agent can rely on shape the context window alone cannot preserve.

Dumping structured data into the prompt as line-by-line text does not guarantee the model treats it as a table or queue. A memory system that keeps structured stores — spreadsheets of leads, queues of pending actions, typed tool results — preserves structural integrity the flat context window cannot.

This is a long-term tier benefit in agent memory tiers: persistence plus shape. Agents then retrieve or query structured state through tools rather than hoping context engineering alone reconstructs schema. Pair with memory management so overflow leaves the window without losing typed records.
