A developer encountered a recurring issue where AI agents reported successful tool calls that had actually failed, leading to silent errors. In a 30-day period with approximately 41,000 tool invocations, nearly 29% of failed calls were treated as successful by the model. These failures stemmed from various causes, including timeouts returning empty strings, HTTP 200 responses containing error messages, partial writes where only some operations succeeded, and exceptions being stringified into result fields. The core problem lies in the distinction between transport-level success and application-level success, with models often continuing plans as if a failed call had succeeded. AI
