## Why apply_memory_retention_batch is rated Medium

This tool modifies memory state by applying approved items in batch operations. While the governance framing ("approved", "trusted internal backup") suggests safeguards are in place, the core action is a write operation that changes persisted data.

From the tool's own definition: "Tool applies approved items to memory, with language suggesting batch modification ('apply', 'atomically apply')."

## Use case

AI agents use apply_memory_retention_batch to create or update resources in Mapi Agent Memory, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mapi Agent Memory environment.
