AI agents call get_all_submissions to retrieve information from Leetcode without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns submission data without creating, modifying, deleting, or executing any operations. It has no side effects and presents minimal risk even if misused by an agent, as it only exposes information the authenticated user already has access to.
From the tool's definition Tool name 'get_all_submissions' and description 'Retrieves a paginated list of the current user' indicate data retrieval with no modification.

Yes. Add a rate_limit block to the get_all_submissions 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.
