Same Model, Different Standards: The Claude API vs CLI Code Review Divide

This investigation exposes a critical consistency problem in production AI: the same Claude model delivers dramatically different code review results via CLI versus API. While the CLI surfaces 7 precise, actionable bugs, the API variants overwhelm with 44-84 findings filled with false positives, training developers to ignore warnings. For teams building AI-driven tools, it's a sobering reminder that how you interface with a model matters as much as which model you choose.
