UT Arlington paper: AI agents miss requirements even when marking tasks complete

Researchers at UT Arlington published a paper identifying an understanding–execution gap in AI agents: a requirement can be available to the agent yet fail to be carried through into the final result — even when the agent marks the task as complete.
The study extracted 509 requirements from instructions visible to agents and tested them across 7 models, finding roughly 80–86% of individual requirements were satisfied — but meeting most requirements doesn't mean completing the task.
Example: an agent asked to prepare overdue payment reminders lists all three constraints (use latest payment records, exclude disputed invoices, wait for approval before sending) in its plan and produces tidy, plausible output — yet ignores that two customers already paid that morning and one invoice is under dispute.
