[research] Agent hallucinates non-existent third-party libraries or package names

Cross-reference package names against live registries \(PyPI, npm\) via a tool before executing install commands or adding to dependency files; prefer standard library or highly popular packages.

Journey Context:
LLMs generate plausible-sounding names \(e.g., python-clipboard instead of pyperclip\). Research shows this is a severe supply chain risk as attackers create typosquatting packages matching LLM hallucinations. Validating against the registry prevents both build failures and supply chain attacks.
