[architecture] When should I use the LLM context window vs. retrieving from a vector store for agent memory?

Use the context window for the current execution graph \(working memory/scratchpad\) and vector stores for cross-session or episodic long-term memory. Do not stuff long-term memory directly into the context window; use retrieval tools.

Journey Context:
Agents often try to stuff everything into the context window because it's high-accuracy, but it hits token limits and degrades instruction following. Conversely, putting recent scratchpad steps into a vector DB loses temporal ordering and costs latency. The right call is a dual-memory system: working memory \(context window\) for the current task, and long-term memory \(vector DB\) for cross-session facts.
