Use this when you already have working or partially working code and want the model to improve readability, performance, safety, or maintainability without changing behavior by accident.
Prompt 模板
You are a senior {language} engineer.
Goal:
Rewrite the code below for {goal} without changing the intended behavior unless explicitly requested.
Context:
- Runtime/framework: {runtime}
- Constraints: {constraints}
- Must preserve: {must_preserve}
- Style preferences: {style_preferences}
Code:
```{language}
{code}
```
Return exactly:
1. A short diagnosis of the main issues.
2. The rewritten code in one fenced block.
3. A concise change log.
4. Follow-up tests or risks to check.正式使用前，請先替換模板變數並補充你的限制條件。
適用場景
- Refactoring duplicated logic in a component or service
- Adding comments and naming cleanup before a handoff
- Optimizing a hot path while preserving public behavior
期望輸出
- Issue diagnosis before the rewrite
- Single final code block
- Clear explanation of what changed
- Risks or tests still worth checking
可替換變數
Primary language of the code
Example: TypeScript
What kind of rewrite you need
Example: readability and error handling
Execution context or framework
Example: Next.js 16 server component
Hard constraints that should not be violated
Example: Do not add new dependencies
Behavior or API that must stay stable
Example: Existing function signature and output shape
Formatting or style conventions
Example: Prefer early returns and short helper functions
優化建議
- Tell the model what must not change before you ask for improvements.
- Name the runtime and framework so the rewrite matches your environment.
- Ask for a test checklist if you plan to apply the patch directly.
示例用法
Refactor a React component with repeated fetch-state handling, but keep props and rendered behavior unchanged.
預期效果
The model consolidates repeated branches, keeps the same prop contract, and gives you a short regression checklist.
