    "body_text": "The benchmark contains 3,418 conversational inputs derived from 128 templates plus 33 scenarios that separate time calculation from action. Across 13 models, assistants account for time-dependent constraints in 30.5 percent of cases where the requested action violates a rule, while seldom warning unnecessarily. In 62.1 percent of failures, the model had calculated the elapsed time correctly. Supplying timing explicitly fixes only about half. TASC is a benchmark of templated everyday constraints, but it exposes a practical gap between temporal reasoning and advice.",
