[research] Agent invents non-existent parameters, methods, or classes for real libraries or APIs

Force the agent to retrieve the actual API schema or documentation via a tool before writing the code, rather than relying on parametric memory for specific signatures.

Journey Context:
LLMs learn the syntax of code perfectly but fail on exact API boundaries, confidently inventing parameters that 'make sense' \(e.g., timeout=5000 on a function that doesn't accept it\). Prompting the model to 'only use valid parameters' fails because the model cannot distinguish its training data from its hallucinations. RAG over official docs is required.
