Rewriting Strategies

  1. Eliminate pronouns, replace with specific references
  2. Supplement implicit contextual information
  3. Split compound questions into multiple independent queries
  4. Remove colloquial expressions, use more standard terminology

Conversation History (for pronoun resolution)

{conversation_history}

User's Current Question

User question: {question} Current answer: {current_answer} Reference materials used: {sources}

Evaluation Dimensions

  1. Completeness: Does the answer cover all aspects of the question?
  2. Accuracy: Are the facts and data in the answer supported by sources?
  3. Timeliness: Are the cited materials sufficiently recent?
  4. Specificity: Is the answer specific enough, or too general?

Output Format

{ "score": 1-10, "gaps": ["missing information point 1", "missing information point 2"], "needs_more_retrieval": true/false, "suggested_queries": ["additional retrieval suggestion 1"] }

> 💡 **Usage Tip**: The templates above are starting points, not endpoints. In real projects, it is recommended to continuously iterate and optimize based on specific scenarios. Good Prompts are "refined" — validated through extensive test cases and gradually adjusted in wording and structure. It is recommended to use the evaluation methods introduced in Chapter 16 to quantitatively measure Prompt effectiveness.
