Report #47088

[research] ModuleNotFoundError from hallucinated pip/npm packages

Cross-reference package names against official registries \(PyPI, npm\) via tool-use before suggesting or installing; default to standard libraries if uncertain.

Journey Context:
LLMs predict statistically likely package names, often blending concepts into non-existent packages \(e.g., python-requests-fast\). Attackers exploit this by creating malicious packages matching LLM hallucinations \(squatting\). Blind installation is a security and factuality failure.
