Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure, and it says nothing about where the project is saved, whether it overwrites the existing file, whether it is reversible, or whether it can fail. 'Save' implies mutation but the description never confirms persistence, side effects, or failure conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
