  "why_included": "Parallel tool calls now validate against JSON schema before execution — a whole class of agent failures disappears.",
  "summary": "Strict mode extends to parallel tool calls: every call is schema-validated pre-execution, with a repair pass on failure. Available in the API and Codex.",
  "practical_implication": "Delete your hand-rolled tool-call validators. Turn on strict mode and move validation effort to eval coverage instead.",
  "agent_context": "OpenAI strict structured outputs now cover parallel tool calls. Schema-validated pre-execution with one repair pass. Remove custom validators; rely on strict mode + evals.",
