Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already signal destructiveHint=true and openWorldHint=false. The description adds that the public URL stops serving content, which is the operative behavioral effect, but it does not mention reversibility, state prerequisites (e.g., must be currently published), or whether existing pending runs are affected. With annotations carrying the safety signal, this is acceptable but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
