Report #68969

[research] Hallucinating parameters or methods for real, existing libraries or APIs

Inject the exact, version-pinned API schema or source code into the context window before generating the call. Do not rely on the model's parametric memory for API signatures.

Journey Context:
LLMs memorize training data, but APIs evolve. A model might blend parameters from v1 and v2 of an API, or mix up similar libraries. Parametric memory is lossy for exact signatures; grounding on the specific schema eliminates this.
