ChainZCode: Reproducibility Package for Zero-Shot vs. Chain-of-Thought Python Code Generation

Reproducibility package for the preprint "Zero-Shot vs. Chain-of-Thought Prompting for Python Code Generation." It contains the 180 retained Python implementations (30 tasks × GPT-4o, Claude 3.5 Sonnet, Gemini 2.0 Flash × zero-shot/CoT), the task prompts, retrospective task contracts, reference checks, adapters, the evaluation worker, per-case results, and normalized judge-score data. The functional evaluation and article tables can be reproduced locally without provider credentials.
