Session memory
Also known as: short-term memory (session)
Session memory is what an agent carries within one session: the conversation so far, plus often a rolling summary of earlier steps.
- Lives in the context window (plus a summary when it overflows).
- Clear at session end, unless explicitly persisted.
- The working memory of the current task.
The limit: session memory is bounded by the context window. When it fills, you summarize, retrieve, or spill to long-term memory — that management *is* the design.
