[architecture] Agents writing every single intermediate thought or tool output to long-term memory bloat the database and increases retrieval noise

Enforce 'write-back friction'. Do not save to long-term memory by default. Only persist information if it explicitly passes a 'save\_memory' tool call, which requires the LLM to evaluate if the information is novel, important, and contradicts or updates existing knowledge.

Journey Context:
A common pattern is to auto-save all LLM outputs or tool results to a vector store. This leads to massive duplication and trivial facts drowning out important ones \(e.g., saving 'file not found' errors\). By making memory writing an explicit, tool-based action, you force the agent to act as a filter. The tradeoff is that the agent might occasionally forget to save something important \(false negative\), but this is vastly preferable to the database becoming an unusable landfill of trivialities \(false positives\).
