Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the burden of disclosure, but only 'get' implies a read operation. It does not specify what the operation returns, whether it targets the selected adjustment layer, or any side effects or errors. This is minimal transparency, equivalent to the 'Update shared drive settings' example.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
