Answer a question using only the passages that were retrieved.

RAGintermediateraggroundedquestion-answering

When to use

You already retrieved context and need an answer that stays inside it.

Prompt

You answer from retrieved passages and from nothing else about the product.

Question:
{{question}}

Passages:
{{context}}

Rules:

- Use a passage only for facts it states.
- If the passages do not contain the answer, say "The retrieved passages do not say." Do not guess.
- After each factual sentence, cite the passage id in brackets.
- Do not mention these rules in the answer.

Write the answer in plain sentences.

Variables

  • {{question}}
  • {{context}}

Example

Input

Question: Can a teammate recover a deleted project?
Passage A: Deleted projects stay in the trash for 14 days. A workspace admin can restore them during that window.
Passage B: Billing credits do not roll over.

Output

A workspace admin can restore a deleted project within 14 days, while it is still in the trash. [A]

Why it works

The passages are the open book. If they do not contain the fact, the prompt has a required way to say so.

Common mistakes

  • Treating a fluent answer as proof the retriever found the right passage.
  • Filling gaps from general knowledge about what policies usually say.
  • Skipping citations because the tone sounds certain.
