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. It clearly indicates a state-changing operation and states that the updated project detail is returned. However, it does not disclose whether dropping is reversible, idempotent, or affects related tasks/resources, which would be helpful for a status-mutating tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
