[research] Suggesting non-existent packages or libraries \(Package Hallucination\)

Cross-reference generated package names against a live registry \(PyPI, npm\) or a curated allowlist before executing install commands or presenting the code to the user.

Journey Context:
LLMs hallucinate plausible package names because they predict tokens based on naming conventions \(e.g., 'python-requests-fast'\). Attackers actively register these hallucinated names with malicious code \(squatting\). Relying on parametric memory for package names is a security risk and a factual error; live verification is mandatory.
