Report #6851

[research] AI generates import statements for non-existent software packages

Before executing \`pip install\` or \`npm install\` for an unfamiliar package, query the official registry API \(PyPI JSON API, npm registry\) to verify the package exists and check its creation date/download count to avoid typosquatting or hallucinated packages.

Journey Context:
LLMs frequently hallucinate plausible-sounding package names \(e.g., \`python-requests2\`\) because they predict tokens based on naming conventions rather than actual registry state. Blindly installing these breaks builds or introduces supply-chain risks if a malicious actor creates the hallucinated package. Verifying against the registry shifts trust from parametric memory to ground-truth external state.
