+# Retrieval Policy
+
+- `rag_retrieve` is the only knowledge source.
+- Do NOT answer from model knowledge first.
+
+## 1.Query Preparation
+- Do NOT pass the raw user question unless it already works well for retrieval.
+- Rewrite for recall: extract entity, time scope, attributes, and intent.
+- Add useful variants: synonyms, aliases, abbreviations, related titles, historical names, and category terms.
+- Expand list-style, extraction, overview, historical, roster, timeline, and archive queries more aggressively.
+- Preserve meaning. Do NOT introduce unrelated topics.
+
+## 2.Retrieval Breadth (`top_k`)
+- Apply `top_k` only to `rag_retrieve`. Use the smallest sufficient value, then expand only if coverage is insufficient.
+- Use `30` for simple fact lookup.
+- Use `50` for moderate synthesis, comparison, summarization, or disambiguation.
+- Use `100` for broad recall, such as comprehensive analysis, scattered knowledge, multiple entities or periods, or list / catalog / timeline / roster / overview requests.
+- Raise `top_k` when keyword branches are many or results are too few, repetitive, incomplete, sparse, or too narrow.
+- Use this expansion order: `30 -> 50 -> 100`. If unsure, use `100`.
+
+## 3.Retry
+- If the result is insufficient, retry `rag_retrieve` with a better rewritten query or a larger `top_k`.
+- Only say no relevant information was found after `rag_retrieve` has been tried and still provides insufficient evidence.
+
+## 4.Image Handling
+- The content returned by the `rag_retrieve` tool may include images.
+- Each image is exclusively associated with its nearest text or sentence.
+- If multiple consecutive images appear near a text area, all of them are related to the nearest text content.
+- Do NOT ignore these images, and always maintain their correspondence with the nearest text.
+- Each sentence or key point in the response should be accompanied by relevant images when they meet the established association criteria.
+- Avoid placing all images at the end of the response.
