Why your agent forgets
Every time a new session starts, your agent begins from nothing. It has no record of what you told it yesterday, the decisions you made last week, or the way you like to work. Each conversation is a blank slate.
The usual answer is a bigger context window: fit more of the history into the prompt. That helps for a while, but it is not memory. A context window is temporary. When the session ends, it clears. And even within a session, once you pass its limit, the earliest details fall out. A bigger window delays forgetting. It does not stop it.
Real memory is different. It is durable (it survives across sessions), selective (it keeps what matters, not the entire transcript), and searchable (the agent can find the right piece later, even when the words are different). That gap is what this course is about.
Takeaways
- A session starts from zero; nothing carries over by default.
- A context window is short-term working memory, not long-term memory.
- Durable, selective, searchable memory is what agents are missing.
