AI agents use set_loyalty_status to create or modify resources in Award Travel Finder. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call set_loyalty_status repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Award Travel Finder.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.
