AI agents use promakeup_emit_listing_event to create or modify resources in Pro Makeup. 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 promakeup_emit_listing_event 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 Pro Makeup.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Use AFTER successfully referring a user to a listing, or when the user signals data quality (wrong phone, closed). Mirrors /api/listing-events vocabulary. Allowed event_types: bad_phone, closed_business, wrong_address, unanswered_within_24h, consumer_lead, pricing_question, booking_inquiry. Requires a Bearer token with the listing-events:write scope — see https://pro.makeup/.well-known/auth.md to request one..

promakeup_emit_listing_event is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the promakeup_emit_listing_event 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.
