Report #69655

[research] Hallucinating non-existent API parameters or library methods

Inject official, version-specific documentation into the context window prior to generation, or use tool-use to query the library's \`help\(\)\` or \`dir\(\)\` dynamically at runtime.

Journey Context:
Models blend training data from different library versions, creating chimera APIs \(e.g., mixing pandas v1 and v2 arguments\). Static prompting fails because the model defaults to stale weights. Dynamic grounding via doc injection \(RAG\) or runtime introspection forces the model to attend to the correct, current signatures rather than guessing from prior distributions.
