Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives no guidance on when to use this tool versus the siblings (citation, normalize-url, parse-url, validate-json, timezone, etc.). There is no mention of intended use cases, exclusions, or alternatives. An agent would have no basis for selecting this tool over others.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
