Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only says 'Get full details,' which implies a read operation, but it does not describe possible errors (e.g., task not found), return structure, or any prerequisites. For a simple getter this is thin; it adds no safety or failure mode context beyond the intuitive read-only nature.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
