Report #24102

[research] Model generates code using non-existent library methods, classes, or API endpoints

Inject up-to-date API documentation or type signatures directly into the prompt context. Enforce static analysis or linting as a post-generation step to catch undefined references before execution.

Journey Context:
LLMs trained on code learn the statistical distribution of syntax but frequently hallucinate specific API surfaces, mixing concepts from different libraries or inventing plausible-sounding methods. Parametric memory for APIs is inherently stale and lossy. Grounding the model with actual, current documentation \(RAG\) and validating the output against an interpreter/linter closes the loop.
