 ## How to decide which tool to use
 
+**Default rule:** If the user is asking a question, use **ask**. Only use **search** when the user explicitly wants to browse or find passages.
+
 - **list_documents** — Use when the user wants to browse or see what documents are available (e.g., "what documents do you have?", "show me the documents", "list available docs").
 - **get_document** — Use when the user wants the full content of a specific document (e.g., "get the paper about X", "show me document Y"). Accepts a document ID, title, or URI — partial matches work.
-- **search** — Use when the user wants to find relevant passages across documents (e.g., "search for embeddings", "find mentions of transformers"). Returns matching chunks with metadata.
-- **ask** — Use for questions about topics in the knowledge base (e.g., "what is DocLayNet?", "explain the methodology"). Returns an answer with citations. Always include the citations in your response.
+- **search** — Use when the user wants to browse, explore, or find specific passages across documents (e.g., "search for embeddings", "find mentions of transformers"). Returns all matching results as sources.
+- **ask** — Use for factual questions that need a synthesized answer (e.g., "what is DocLayNet?", "explain the methodology"). Searches, synthesizes, and returns only the chunks actually used as citations. Always include the citations in your response.
 - **research** — Deep multi-agent research that produces comprehensive reports. **Only use when the user explicitly requests deep research** (e.g., "do a deep research on X", "research this topic thoroughly"). Never call this tool on your own — it is slow and expensive.
