WHAT IT DOES

What swarmtrade_rate does on Swarmtrade

AI agents use swarmtrade_rate to create or update resources in Swarmtrade — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Swarmtrade environment.

WHY IT NEEDS A POLICY

Why swarmtrade_rate needs a policy

This tool creates or modifies reputation/rating data for a trade counterparty. It is a Write operation as it posts a rating record. While it affects reputation which could influence future trades, it does not directly move money, delete data irreversibly, or execute code. Severity is medium because manipulated ratings could harm counterparties' ability to trade and undermine trust in the platform.

Verdict

swarmtrade_rate Rate-limited

swarmtrade_rate stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
