Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states 'Patch specific fields' and 'merged into current config', which hints at a non-destructive merge behavior. However, it lacks critical details: whether this requires admin permissions, if it's idempotent, what happens on invalid fields, rate limits, or error responses. For a configuration mutation tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
