Long-running AI agents fail due to stale, contradictory memory, not context limits
oki098isg_t · reddit · 2026-08-31
A developer building production AI agents identifies memory staleness and contradiction as a critical failure mode, distinct from context window limits. Old facts persist as current, corrections fail to reliably overwrite them, and agents confidently act on outdated info after hours. The key challenge is ensuring stored information remains trustworthy—specifically, how to invalidate outdated "truths" rather than just adding new rows and hoping retrieval favors the correct one.
