[research] Generating code that calls non-existent library functions or API endpoints

Ground code generation by providing actual API documentation or library source code in the context. Post-validate generated code using an Abstract Syntax Tree \(AST\) parser or a sandboxed linter to catch undefined references before presenting to the user.

Journey Context:
LLMs are excellent at mimicking syntax but poor at recalling exact API signatures. They will confidently invent functions like \`utils.parse\_json\_safe\(\)\` or \`pandas.read\_parquet\_to\_df\(\)\` because it fits the semantic context. Relying on the model's parametric memory for API specifics is the primary failure mode for coding agents.
