[architecture] Agent memory bloated with useless tool outputs and trivial observations, drowning out important facts

Implement a 'reflection' or 'critic' step before writing to long-term memory. Only persist information that passes a relevance or novelty filter relative to the agent's core goals and existing memory.

Journey Context:
Agents that automatically save every observation, tool response, or conversation turn into their long-term memory quickly suffer from write amplification. The vector store becomes a noisy landfill of stack traces, API responses, and pleasantries. This makes future retrieval highly imprecise \(low signal-to-noise ratio\). The solution is to treat memory writes as expensive operations. By using a smaller LLM call or heuristic to ask 'Is this novel and important?' before writing, you drastically reduce noise and improve future retrieval accuracy, at the cost of a slight increase in write-time latency and the risk of occasionally forgetting a seemingly trivial but ultimately important detail.
