[architecture] Building an agent as a stateless API wrapper and bolting on a vector database as an afterthought

Design the agent memory-first. Define the schemas for Core Memory \(mutable scratchpad always in context\), Archival Memory \(infinite vector store\), and Recall Memory \(searchable chat history\) before writing the agent's system prompt or tools.

Journey Context:
Developers often build the LLM tool-calling logic first, then realize the agent forgets things and slap on a generic vector wrapper. This leads to fragmented memory where the agent dumps everything into one bucket. Memory-first design forces you to categorize data by access patterns: what needs to be always-on \(Core\), what needs to be searched \(Archival\), and what is a historical log \(Recall\). This separation prevents context pollution and optimizes retrieval.
