WHAT IT DOES

What store_summary_tool does on Alaya

WHY IT NEEDS A POLICY

Why store_summary_tool needs a policy

The name implies a write operation (storing data), consistent with the server's write capabilities seen in sibling tools like create_note_tool and append_to_note_tool. However, the empty description significantly lowers confidence. Storing a summary is a reversible write action, so Write is the most appropriate category at medium severity given the personal knowledge vault context.

From the tool's definition Tool name 'store_summary_tool' suggests storing/saving a summary; description is empty and uninformative.
