[counterintuitive] Can I trust package names suggested by AI coding assistants?

Verify every new dependency against the official package index before installing. Pin versions and use private registries or allow-lists to block slopsquatting.

Journey Context:
Developers often assume an AI that names a package has verified its existence. A large-scale study of 576,000 generated Python and JavaScript samples found that 19.7% of recommended packages did not exist, with open-source models hallucinating 21.7% of the time and commercial models 5.2%. Worse, 43% of hallucinated names reappeared in every rerun, making them predictable targets for attackers who register the names. The risk is not random noise; it is a repeatable, weaponizable supply-chain attack surface.
