AI agents use repair_or_replace to create or modify resources in Sundr Repair Advisor. 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 repair_or_replace 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 Sundr Repair Advisor.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.
