第1次提示詞

概要：
請求創建一個高質量的中譯英助手提示詞模板，要求模板結構清晰，包含變量、指令、示例等部分，并使用XML格式輸出。

目標：

1. 根據任務描述（中譯英助手）創建結構化的提示詞模板。
2. 使用{{變量}}格式定義變量名（僅包含字母、數字和下劃線）。
3. 包含清晰的指令（用<instructions>標簽），說明如何完成任務，并避免輸出XML標簽。
4. 提供相關示例（用<example>標簽）。
5. 輸出語言與任務描述一致（中文）。
6. 最終輸出為XML格式，以<instruction>開頭。

原始 Prompt：

user\n\nHere is a task description for which I would like you to create a high-quality prompt template for:\n
<task_description>\n
你是一個中譯英 的助手\n
</task_description>\n
Based on task description, please create a well-structured prompt template that another AI could use to consistently complete the task. The prompt template should include:\n- Descriptive variable names surrounded by {{ }} (two curly brackets) to indicate where the actual values will be substituted in. Choose variable names that clearly indicate the type of value expected. Variable names have to be composed of number, english alphabets and underline and nothing else. \n
- Clear instructions for the AI that will be using this prompt, demarcated with <instructions> tags. The instructions should provide step-by-step directions on how to complete the task using the input variables. Also Specifies in the instructions that the output should not contain any xml tag. \n
- Relevant examples if needed to clarify the task further, demarcated with <example> tags. Do not use curly brackets any other than in <instruction> section. \n
- Any other relevant sections demarcated with appropriate XML tags like <input>, <output>, etc.\n

第2次提示詞

概要：
從輸入文本中提取變量名（格式為{{變量}}），并輸出為JSON列表格式。若無變量則返回空列表。

目標：

1. 從輸入文本中提取所有{{變量}}格式的變量名。
2. 變量名需符合規范（僅字母、數字、下劃線）。

4. 若無變量則返回空列表[]。
5. 禁止輸出XML標簽或其他內容。
6. 輸入文本是一個XML格式的中譯英助手模板，需從中提取變量名（如{{chinese_text}}和{{english_translation}}）。
