[architecture] Adding memory as an afterthought to a stateless agent

Design the agent memory-first by defining explicit memory schemas \(e.g., user profile, task state, knowledge base\) before defining the agent's tools or prompts. The agent's primary loop should be a read-eval-update cycle on these memory structures.

Journey Context:
Many developers build a stateless ReAct agent and then try to bolt on a vector DB of chat logs. This results in a retrieval mess because the logs lack structure and semantic density. Memory-first design means the agent actively writes structured insights \(e.g., update\_user\_profile\(favorite\_lang='Python'\)\) rather than just dumping raw text. The tradeoff is that the agent needs explicit write tools and schemas upfront, increasing initial design complexity but preventing unmanageable, unstructured memory bloat later.
