How to use this prompt
Paste the smallest relevant code block. Review, test, and lint any generated code before merging; models can hallucinate APIs.
- Copy the full prompt above.
- Replace the bracketed placeholders with your own details.
- Paste it into chatgpt, claude, gemini (or your preferred AI tool).
- Iterate on the output: add constraints, ask follow-ups, or combine multiple results.
Why this prompt works
It gives the AI a clear role, specific inputs, and an output format. That structure reduces vague responses and gives you a draft you can refine in minutes instead of hours.
常见问题解答
What if the code doesn't show auth logic?
State the assumption and flag the missing auth detail for verification.
Can I generate docs for a whole API?
Yes, but process endpoints one at a time or in small groups for better accuracy.
