[architecture] Building an agent by defining tools first and treating memory as an afterthought

Adopt a 'memory-first' design: define the agent's core memory schema \(what it must remember to act\) before defining its tools, and design tools to output structured data that updates this memory.

Journey Context:
Standard agent frameworks encourage defining Python functions \(tools\) first, and letting the LLM figure out what to remember via a generic 'save\_memory' tool. This results in agents that can act but have no persistent state or evolving understanding. If you design the memory schema first \(e.g., 'This agent needs to track user\_intent, current\_workflow\_state, and learned\_preferences'\), you constrain the agent's behavior and ensure tools are built to mutate this state predictably. The tradeoff is less flexibility, but massive gains in reliability and debuggability because the agent's state is a known, typed object rather than a bag of unstructured vectors.
