WHY IT NEEDS A POLICY

Why smart_capture_tool needs a policy

The description is empty, so classification relies on the tool name and server context. 'Capture' in a knowledge vault context typically means creating or storing new notes/data, which maps to Write. Sibling tool 'capture_to_inbox_tool' reinforces this interpretation. Confidence is lowered due to the lack of a description.

From the tool's definition Tool name 'smart_capture_tool' and server context describing 'full read, write, search, and synthesis operations on notes'; sibling tools include 'capture_to_inbox_tool' suggesting capture tools write/store data.
