Report #47412

[synthesis] Model generates code snippets missing import statements or containing excessive boilerplate

Explicitly request 'a complete, runnable script with all necessary imports and no extraneous boilerplate', as default code generation verbosity and completeness vary drastically across models.

Journey Context:
GPT-4o often assumes a REPL environment where imports \(like import os or import json\) are already present, outputting code that throws NameError if run directly. Claude 3.5 Sonnet generally includes all imports but can add excessive comments and boilerplate setup. Gemini 1.5 Pro leans towards highly verbose, enterprise-style boilerplate. To get a uniform, clean, runnable script, you must explicitly constrain the output to include imports and exclude boilerplate, as the default 'helpful' coding behaviors differ significantly.
