[architecture] Agent saves every single interaction and tool output to long-term memory, flooding the vector store with noise and degrading retrieval quality

Implement an importance scoring step before writing to long-term memory. Use a fast, cheap LLM call to rate the memory on a scale of 1-10 based on how surprising, impactful, or permanently useful the information is. Only persist memories above a threshold.

Journey Context:
Storage is cheap, so developers often log everything. However, retrieval quality degrades as the ratio of signal-to-noise in the vector DB drops. If the agent saves 'User said hi' and 'User's dog died', the trivial memories drown out the critical ones. By scoring importance at write-time, you keep the vector store dense with high-signal data, drastically improving downstream retrieval precision.
