Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the burden of behavioral disclosure. It only repeats the word 'update' and gives no information about side effects, whether unspecified fields are reset or preserved, prerequisites, authentication requirements, or consequences for active pricing. This is a mutation tool, yet the description reveals no behavioral context beyond the operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
