glossary / pre-flight check
A pre-flight check is a quick query an agent makes before calling a tool to learn whether it is healthy, how to shape the input, and what to use if it is down.
One pre-flight call (prepare_tool_call) can return a verdict, a known-good input recipe, the expected output shape, a suggested timeout/retry, and a live alternative — cutting failed calls.
