[architecture] Agent runs out of context window during long tasks and loses track of goals

Design with explicit memory tiers: working/context, recall \(recent\), and archival \(long-term\). Move data between tiers based on relevance and recency rather than keeping everything in the prompt.

Journey Context:
The common mistake is treating the LLM context window as RAM. As conversations grow, you either truncate \(lose information\) or hit token limits. MemGPT/Letta showed that agents need an operating-system-like memory hierarchy: a fixed-size context \(working memory\), a recall store of recent events, and archival storage for facts. The key insight is that the LLM should be involved in memory management—deciding what to move, summarize, or retrieve—not just passive truncation. This adds latency and complexity but prevents unbounded growth and information loss.
