A teammate submits shaky input validation code. Which review comment is the strongest?
Multiple choiceEasychapter-17-curatedpremiumsecurityinput-validation
Answer and explanation
Correct answer
D. Make the rule clearer and easier to explain. Validate formats and invariants at the first responsible boundary so later code can rely on the data honestly.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Assuming user or partner input is well-formed spreads insecurity through the entire workflow.
