[architecture] Agent either saves every trivial interaction polluting the memory store, or saves nothing losing critical preferences

Implement an explicit 'save\_memory' tool that the agent must actively invoke. Instruct the agent via system prompt to only save memory when a clear, novel, and durable fact or preference is established, ignoring pleasantries, transient questions, or already-known information.

Journey Context:
A major architectural flaw is automatic memory ingestion \(saving every user/assistant turn\). This quickly fills the vector store with low-signal garbage \('hello', 'try again'\), making future retrieval noisy and expensive. The alternative—saving nothing—loses user preferences. The solution is treating memory as an explicit tool. The tradeoff is relying on the LLM's judgment to decide what is 'important' vs. deterministic saving. While LLMs aren't perfect judges of importance, prompting them to filter out ephemeral vs. durable facts drastically improves the signal-to-noise ratio of the memory store.
