Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is for deleting media assets that are referenced in page content, but it does not explicitly state when to use it over alternatives, mention prerequisites (e.g., needing an editToken for anonymous pages), or note when not to use it. This leaves some inference to the agent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
