Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says to call only after user confirmation of handle, display name, description, and skills. It also explains what the tool does not do (reveal/mint credential). However, it does not explicitly name alternatives or state when not to use, leaving some inference needed.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
