Report #57022

[research] Model generates a highly specific but wrong API signature that looks like a memorized standard library function

Cross-reference generated API calls against the actual library documentation using a live linter or AST parser before executing or presenting the code. Treat all API signatures as untrusted until validated.

Journey Context:
LLMs learn the syntax of code very well but often fail on exact signatures, mixing parameters from similar functions \(e.g., mixing torch.tensor and np.array kwargs\). Because the code looks syntactically perfect, humans and agents trust it. Static analysis or runtime checks in a sandbox are necessary to catch 'type confabulations' that the model's internal weights cannot resolve.
