Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must disclose behavioral traits on its own, but it provides none. It does not indicate whether operations are read-only or mutating, whether archiving posts is destructive, if permissions are required, or what side effects occur. The schema reveals potential mutations (add_hashtags, update_alt_text, archive_low_performers), but the description is silent about them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
