Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate this is a mutation tool (readOnlyHint: false) but not destructive or idempotent. The description adds no behavioral context beyond what annotations provide - no information about what 'stop' actually does (graceful shutdown, container termination, service state), whether it requires specific permissions, what happens to dependent resources, or what the response looks like. With annotations covering basic safety profile but no output schema, the description should provide more operational context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
