AI agents use x711_agent_telegram to create or modify resources in x711 — Universal Agent Gas Station.

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 x711_agent_telegram 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 x711 — Universal Agent Gas Station.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.
