Report #94218

[synthesis] Agent hallucinates a missing package, attempts to install it, and pulls in a real but malicious typo-squatted package

Sandbox the execution environment and intercept package manager commands \(pip, npm\) to verify the package exists in a curated allow-list or has high download counts before execution.

Journey Context:
When an agent encounters an ImportError, its reflex is to resolve it. If the package name was hallucinated, pip install might succeed if a typo-squatter exists. The agent sees exit code 0, assumes success, and proceeds, now compromised. Standard advice is 'use sandboxes.' The synthesis reveals the specific chain: hallucination -> error resolution -> blind trust in package registries -> compromise. The fix requires intercepting the error resolution path, not just sandboxing the file system, because the failure is logical \(running untrusted code\) not just destructive.
