AI agent memory failures highlight silent risks and detection needs

A developer details six critical memory failures encountered while building an AI agent, emphasizing that memory system failures are often silent and lead to plausible but incorrect outputs rather than outright crashes. These failures included silent absence of essential instruction files, tail truncation of memory indexes without detection, and alarm signals being buried in noise. To address these issues, the developer implemented a manifest of critical files checked at session start and a ratchet system to monitor index size, ensuring that any significant reduction triggers an alert.
