Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds the HTTP method and path, which is useful but minimal. It does not disclose any additional behavioral details such as whether the result is limited to active transcode sessions, whether pagination applies, or what the response shape represents.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
