One memory config across multiple agent types will quietly ruin all of them
Adventurous_Whole973 · reddit · 2026-09-16
An engineering retrospective on agent memory: shipping one extraction config for all agent types yielded mediocre memory for everyone. Support agents need ticket context, sentiment trajectories and aggressive forgetting of resolved issues, while sales agents need deal state, stakeholder graphs and months-long retention of loss patterns. Four things must be configured per agent type: extraction rules, memory-type weighting, per-type decay windows, and retrieval ranking across vector/graph/file stores. A single config fails quietly by confidently returning wrong context. The author advocates generating configs from agent descriptions and checking the last 100 retrievals per agent for type-correctness, not just hit rate.
