Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the outcome ('so it can be watched') but does not disclose side effects, whether registration is idempotent, whether the endpoint is validated at registration time, or how the apiKey is used. This is insufficient for a mutation tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
