[counterintuitive] AI generates code calling methods that don't exist in your library version

Always validate AI-generated API calls against the actual project dependencies using type checking and linting as mandatory verification steps before executing AI-generated code

Journey Context:
AI is trained on code from many versions of libraries. It will confidently use methods from newer versions, deprecated methods, or methods from similar-but-different libraries. This is a distribution shift problem: the training data distribution doesn't match your project's dependency versions. The AI appears confident because the method name is plausible and follows the library's naming conventions. This is one of the most common and insidious failure modes because the code looks correct to humans who are also familiar with the library. Type checking catches this because the compiler has the actual type definitions.
