Report #22960
[research] Generating code that calls plausible but non-existent methods, classes, or parameters in third-party libraries
When generating code using unfamiliar or highly specific libraries, prefer generating standard library solutions or explicitly verify the API signature via a documentation search tool before writing the call.
Journey Context:
LLMs learn the syntax and common patterns of programming languages very well, but their knowledge of specific library APIs is sparse and often mixed up. They will confidently invent a method name that fits the class's semantic pattern \(e.g., Document.get\_text\(\) instead of Document.extract\_text\(\)\). This causes immediate runtime errors. Static analysis or doc-retrieval grounding is necessary for long-tail APIs.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
