AI agents call userDetails to retrieve information from Mailmodo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves contact details without side effects. It is a read-only operation that fetches existing data from the system. While contact information could be sensitive, the read-only nature and typical email platform context place this in the Read category with low severity, as the tool itself does not modify, delete, or execute operations.
From the tool's definition Tool name 'userDetails' and description 'Tool to get all details of a contact' indicate a retrieval operation that queries contact information without modifying data.

userDetails 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 userDetails 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.
