1 / 5 Agent Memory Systems

Ran It Twice

Your agent compacts old turns into a rolling summary once context passes a threshold. Right after compaction it re-runs a database migration it had already run earlier in the same session. What went wrong?

A

The context window overflowed and the provider silently truncated the system prompt holding the instructions

B

The record of completed actions existed only in context and compaction removed it; that state belongs in a durable task ledger

C

The summary was inserted after the newest user message, so the transcript ordering confused the model about what had already run

D

The embedding model changed between turns, so the stored migration memory no longer matched the query that would have retrieved it
