Answer Key and Explanations
Check these only after attempting every question.
1. B - shown to the model and shapes which tool it picks
Write it for the model, and put the guarantee in the code rather than in prose.
2. B - in code, as data, where it can be audited
It is policy rather than a type check, and a schema will happily accept nine thousand.
3. B - the request id and the step name
Arguments cannot distinguish two genuine refunds from two retries of one.
4. B - a required parameter of the function
An instruction produces a control you cannot state a guarantee for and cannot show an auditor.
5. B - after it returns, with the attempt number and outcome
Logged before, a call that timed out after succeeding looks identical to one that never ran.
Practical Check
Apply this module to your own work: complete the module activity for *Tool and Function Calling with External Actions*, then write one sentence naming what your result shows and one naming what it does not.
Strong Answer Pattern
A strong answer names the task, the evidence used, the check performed, and the remaining limitation. It avoids "proved", "guaranteed", or "always" unless the evidence genuinely supports it.
