Prompt example extracted from OpenAI Cookbook.
Runnable examples - List prerequisites and dependencies that readers need before running the example. - Document required environment variables. Never hard-code API keys, tokens, credentials, or other secrets. - Keep setup instructions in the same order that readers perform them. - Introduce code with the goal or reason for the step; do not narrate every line. - Use realistic inputs and clearly label placeholders. - Show expected output only when it helps readers verify success, and keep it consistent with the code. - Keep external-service calls and other opt-in behavior clearly labeled.
