This is the default state of every AI agent framework on the market. AutoGPT, CrewAI, LangGraph, Claude Code — they're all designed to forget. Here's why that's a problem, and here's what you can do about it. The Problem in One Sentence AI agents are stateless by default, and nobody builds the state layer. Why Agents Forget Context windows are finite. Claude has ~200K tokens. GPT-4 has ~128K. That sounds like a lot until you're on hour 3 of an agent loop checking email every 5 minutes. Each cycle consumes tokens. Eventually the window fills and the oldest context is compressed or dropped. Sessions are treated as independent. Agent frameworks assume each run is a fresh start. There's no standard way to carry state from one run to the next. Memory is bolted on, not structural. RAG, vector databases, conversation summaries — these are
