Report #7730

[research] Agent imports non-existent packages or standard library modules that sound plausible but do not exist

Constrain the agent's import generation to a validated list of installed packages \(e.g., via pip list or a predefined requirements.txt context\) and execute the code in a sandbox to catch ImportError.

Journey Context:
LLMs frequently hallucinate packages \(e.g., import python-string-utils instead of import string\) because they predict the next token based on naming conventions rather than actual package registries. This is a severe security and reliability risk. Sandboxed execution is the only reliable filter, as prompting alone cannot bound the infinite space of possible package names.
