[research] Hallucinating non-existent API methods, classes, or parameters when writing code

Ground code generation in static analysis or official documentation retrieval. Never rely on parametric memory for API signatures; always retrieve and cite the official docs before writing the call.

Journey Context:
LLMs are extremely prone to fabricating plausible-looking but non-existent API calls because code syntax is highly predictable, but API vocabularies are vast and change frequently. Eval benchmarks like APIBench show massive hallucination rates without grounding. RAG-based code generation drastically reduces this by forcing the model to read the actual API spec before writing the code.
