AI agents call get_item to retrieve information from Playfab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple data retrieval operation with no side effects. It queries catalog item details without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—exposing catalog item information is a low-severity risk in a game backend context.
From the tool's definition Tool name is 'get_item' and description states it 'Retrieves detailed information about a specific catalog item.' The verb 'Retrieves' and absence of any modification, deletion, or execution language clearly indicate a read-only operation.

get_item is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_item rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_item. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
