Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare this a safe, closed-world read (readOnlyHint true, destructiveHint false, openWorldHint false). The description adds genuinely non-obvious behavioral context beyond them: the dataset is limited to posts published from StreamClipping AI, which tells the agent results may under-report versus native platform analytics. It does not mention any auth or permission requirements, but for a read-only tool with annotations covering the safety profile this is a modest gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
