Silent Agent Failures: Clean runs that do the wrong thing
shishir-mishra · reddit · 2026-08-21
The author warns that "silent failures"—clean runs that produce incorrect results without errors—are more dangerous than crashes in AI agent systems.
- Common Failure Modes: Wrong-target success, misinterpreting empty results, partial completion reported as full, and self-grading.
- Monitoring Gaps: Dashboards miss these errors because they are deviations from intent, not technical failures.
- Proposed Mitigations: Independent verification calls, pre-action expectation diffs, special handling for null results, and caps on irreversible actions.
The challenge is that these mitigations often double costs. The author seeks community input on cost-effective detection methods for production environments.
