AI Agents Are Breaking Silently in Production — and Nobody's Catching It

Reporting from r/artificial on Reddit, the AI agent deployment problem is not that models are too dumb — it's that the infrastructure for knowing whether they're working has never caught up to how fast companies are shipping them. Tool-calling workflows fail quietly. Prompt changes introduce regressions. Most teams have no system to detect either before users do.

One engineer posted an evaluation framework built specifically for agentic workflows: structured test suites that verify tool-calling behavior end-to-end, regression detection for prompt edits, and coverage for the failure modes that demos almost never surface. The response from other developers suggests this problem is widespread, not an edge case.

The deeper issue is cultural. Teams measure AI agent success by whether demos look good, not whether edge cases resolve correctly at scale. That gap is manageable when AI is a side project; it turns expensive the moment agents touch customer-facing systems or internal decision pipelines.

Building the agent is the easy part. Knowing if it works is the job nobody budgeted for.
