[architecture] When to use memory-first agent design vs stateless API calls

Use memory-first design \(where the agent proactively pushes/pulls from memory stores\) only when the task spans multiple distinct contexts or requires long-term user personalization. For single-shot, stateless tool-use tasks, rely purely on the immediate context window to minimize latency and complexity.

Journey Context:
Adding a memory layer \(vector DB, graph DB, reflection loops\) introduces massive architectural complexity, latency, and points of failure. Developers often over-engineer agents with sophisticated memory architectures for tasks that fit entirely within a 128k context window. The tradeoff is capability vs. complexity. If the context window can hold the entire necessary state for the task, memory-first is an anti-pattern. Use memory only when the state exceeds the window or must persist across window resets.
