[research] Agent imports and uses non-existent or hallucinated Python packages

Before executing pip install or writing import statements for unfamiliar packages, cross-reference the package name against the PyPI JSON API or a local dependency manifest \(e.g., requirements.txt\). Reject unknown packages.

Journey Context:
LLMs frequently invent package names that sound plausible \(e.g., python-requests2 or smart-string\). Executing pip install on these hallucinations either fails, or worse, installs malicious typo-squatted packages. Checking against a known manifest or the official registry prevents both hallucination and supply chain attacks.
