Why AI agents forget: a primer on the memory layer missing from agent architecture
sharpeye_wnl · x · 2026-11-12
The article explains why most agents forget and how a memory layer fixes it: prompting and context engineering alone can't make stateless agents retain your project conventions and preferences across sessions.
- Problem: each new session starts from zero — stack, constraints and code style must be re-explained.
- Architecture: stateless agents run Query→Agent→Response; stateful agents write learnings to memory during interactions and read back what matters in new sessions.
- Typical pipeline: user query → orchestrator → tools/API/RAG/memory to collect context → LLM responds → memory writer stores info.
- Taxonomy: short-term (buffer, sliding window, summary, token buffer, vector store, entity memory); long-term (episodic, procedural, semantic, self-reflection, memory routing).
