Report #82907

[research] LLM suggests non-existent software packages or libraries

Verify package names against a registry \(e.g., PyPI, npm\) via tool use before executing install commands. Never trust the LLM's memorized package index.

Journey Context:
LLMs trained on code often blend real package names with plausible-sounding fake ones \(e.g., 'utils-secure'\). Blindly installing leads to dependency confusion attacks or runtime failures. Verification is a strict prerequisite because the prior probability of hallucinated packages is surprisingly high in niche tasks, and adversarial package squatting exploits this exact failure mode.
