WHY IT NEEDS A POLICY

Why store_document needs a policy

The name 'store_document' strongly suggests creating or persisting a document in storage (likely Supabase vector store given server context). This is a Write operation. Confidence is reduced due to the empty description — it's possible the tool has broader side effects, but the most straightforward interpretation is a reversible write/upload action.

From the tool's definition Tool name 'store_document' implies writing/storing data; description is empty and uninformative.
