Report #48281

[research] Installing non-existent Python or Node packages suggested by LLM

Cross-reference package names against PyPI/NPM registry APIs before executing install commands or suggesting them to the user.

Journey Context:
LLMs hallucinate plausible-sounding package names because they predict tokens based on naming conventions, not actual registry states. This leads to broken builds or supply chain attacks \(typosquatting\) if a malicious actor creates the hallucinated package. Always verify existence via API before executing dependency additions.
