Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure)Skip and it does add meaningful behavior: sharing a single in-flight job limit with the web app and returning 409 if another job is running. It does not mention the success response shape or asynchronous behavior, but the stated concurrency failure mode is valuable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
