Why most AI agents disappoint in production (and what to fix first)

Demos provide curated data, reliable tools, and stable conditions, while production introduces late-arriving data, conflicting facts, permission constraints, API timeouts, and constantly changing state. Early production deployments are often reduced to safer patterns such as read-only assistance, human-in-the-loop workflows, or narrow domains with curated data. Scaling back occurs after encountering messy real-world constraints, showing that autonomy is unforgiving. As scope increases, weak guarantees lead to overconfident actions on stale information, brittle reasoning when meaning drifts, and compounding errors once agents can write back. Agents must be treated as systems that read, reason, and write against live operational data, requiring guarantees around freshness, semantics, safe write paths, and lineage. Freshness bugs occur when correct reasoning uses the wrong time slice, causing actions that collide with in-flight processes or proceed despite unresolved rollback status elsewhere.

"Four matter more than the rest: freshness, semantics, safe write paths and lineage. Many organizations have learned to live with staleness: batch pipelines, replica lag, caches, delayed CDC (change data capture), materialized views. Humans compensate with judgment. Agents compensate with confidence. A common production failure mode is correct reasoning on the wrong time slice."
