Report #2303

[research] Hallucinating non-existent package names, classes, or API methods in generated code

Cross-reference generated code against official documentation or package registries \(e.g., PyPI, npm\) before execution, or constrain decoding to valid API tokens if using a specialized coding model.

Journey Context:
LLMs are prolific at inventing plausible-looking APIs \(e.g., 'from langchain import MagicSolver'\). This causes immediate runtime errors. Static analysis or execution in a sandboxed environment to verify imports is necessary before presenting code to the user.
