WHY IT NEEDS A POLICY

Why memory_ingest needs a policy

The name 'memory_ingest' implies writing or storing data into the shared memory service. Sibling tools like 'memory_forget' (likely destructive) and 'memory_search' (likely read) provide context that this tool creates or adds memory entries. Without a description, confidence is reduced, but 'ingest' strongly implies a write/store operation.

From the tool's definition Tool name 'memory_ingest' suggests ingesting/writing data into memory; description is empty and uninformative.
