Report #62355

[agent\_craft] Agent tries to keep all user preferences, past project decisions, and long-term facts in the system prompt, eventually hitting the context limit

Externalize long-term memory to a structured database \(e.g., vector store or key-value JSON\), and use a retrieval step only when the current task requires that specific knowledge. Keep the active context window focused strictly on the immediate task.

Journey Context:
There is a strong temptation to stuff the system prompt with 'user profile' and 'project rules'. However, long contexts slow down inference and dilute attention. The MemGPT architecture demonstrated that treating the LLM context as RAM \(fast, limited\) and external storage as Disk \(large, slow\) is optimal. The agent must learn to 'page in' \(retrieve\) and 'page out' \(summarize/evict\) facts, keeping the active working set lean.
