What set-user-limit does on Rabbitmq

WHY IT NEEDS A POLICY

Why set-user-limit needs a policy

The tool creates or modifies user limit settings in RabbitMQ, which is a reversible configuration change. While it alters state, the effect is bounded to user resource constraints rather than destructive deletion or financial operations.

From the tool's definition Tool name 'set-user-limit' indicates modification of user configuration/limits. Description states 'Set a user limit,' which is a configuration change operation.

Verdict

set-user-limit Rate-limited

set-user-limit 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.
