Report #36229

[architecture] Agent saves every single interaction or trivial fact to memory, degrading retrieval precision over time \(the 'hoarder' anti-pattern\)

Implement a memory write threshold. Before saving a fact, evaluate its general utility, uniqueness, and importance. Discard trivial or highly transient facts \(e.g., 'the file is currently open'\).

Journey Context:
Agents equipped with 'save\_memory' tools tend to over-use them, treating memory like a log file. This creates a needle-in-a-haystack problem where the vector store grows with junk, reducing retrieval accuracy. The tradeoff is that an aggressive write filter might miss seemingly trivial facts that turn out to be important later. The solution is to use the LLM itself as a judge of 'salience' before writing, ensuring only high-signal, reusable facts are persisted.
