Moveworks Makes Failed Tool Calls Return Explicit Failure States Instead of Looking Successful
aiagentstore.ai dated weekly index (single source, vendor changelog item)·low signal
Moveworks rolled out a model upgrade to Agent Studio Plugins on Sept 14 so that failed tool calls now return explicit failure and no-results states rather than surfacing as apparent successes. It is a small changelog line with an outsized implication for anyone building on an agent platform: silent tool failure is the failure mode that produces confidently wrong agent output, and vendors are only now instrumenting for it. Worth checking whether your own agent framework distinguishes an empty result from a broken call.
