Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=false, idempotentHint=false, openWorldHint=true, destructiveHint=false, which already establish that this is a non-idempotent write in an open-world context. The description adds nothing beyond that: no mention of required permissions, whether duplicate findings collide, or what is created. It contradicts nothing but contributes zero behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
