Report #15445

[agent\_craft] Agent hallucinates non-existent packages or uses typosquatted packages from untrusted registries

Restrict package installations to verified registries and known packages. If a package is not found, fail safely rather than guessing. Do not execute arbitrary pip/npm install commands from unverified URLs.

Journey Context:
Agents eager to please will try to resolve missing dependencies. Attackers create malicious packages matching common hallucinations. Restricting to known registries and failing safely prevents the agent from becoming a vector for supply chain compromise. OWASP LLM Top 10 \(LLM03: Supply Chain Vulnerabilities\) highlights this exact risk for LLM agents.
