Coding & Development

Code review, debugging, refactoring, architecture

36 prompts

Coding prompts cover code review, debugging, refactoring, architecture decisions, and documentation. The strongest templates specify language, constraints (no new dependencies), and output format (diff vs full file) so the model stays actionable.

Copy a prompt before opening a PR or when stuck on a bug — curator notes often mention temperature and whether the template assumes repo context. Pair with our ChatGPT prompt engineering guide for best results.
