Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says when to use this tool ('when a user wants to talk to, hire, or get a consultation'). It provides clear context, though it does not explicitly mention when not to use it or list alternatives. Sibling tools are sufficiently different, so no exclusion is necessary.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
