AI agents use register_agent_wallet to create or modify resources in Kustodia Escrow. 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 register_agent_wallet 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 Kustodia Escrow.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.
