Report #24270

[agent\_craft] Importing Non-Existent or Typosquatted Packages \(Package Hallucination\)

Never generate an import statement for a package not present in the project's existing dependency manifest \(e.g., package.json, requirements.txt\) unless it is a highly canonical, standard library \(e.g., os, react, numpy\). If suggesting a new package, require the user to verify it.

Journey Context:
LLMs frequently hallucinate package names \(e.g., python-requests instead of requests\). Attackers register these hallucinated names on PyPI/npm and push malware. This is a Supply Chain Vulnerability \(OWASP LLM Top 10 LLM03\). Relying solely on the LLM's training data for package existence is a known vulnerability. The fix introduces a 'trust-but-verify' step anchored in the local filesystem state.
