Why query_text needs a policy

The tool performs a query operation against a knowledge graph or document store. Querying is fundamentally a read operation that retrieves information without side effects. No data is created, modified, deleted, or destroyed. The 'various retrieval modes' are alternative strategies for fetching existing information, not performing mutations. This fits the 'Read' category (search, list, get, fetch operations).

From the tool's definition Tool name 'query_text' and description 'Query LightRAG with text using various retrieval modes' indicate a retrieval operation that reads/queries data without modifying or deleting it.
