Does the description explain when to use this tool, when not to, or what alternatives exist?
The instruction 'only include the fields you want to change' gives useful guidance on how to call the tool as a partial update. However, it does not explicitly state when to use this tool instead of invite_user, remove_user, or update_client, leaving that distinction to naming inference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
