Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies when to use this tool: when a stable, immutable classifier version is needed for pinning, vs iterating on the draft. It does not explicitly name alternative tools (e.g., update_classifier, create_classifier, publish_extractor_version), but the workflow context ('Published versions never change — keep iterating on the draft') provides clear usage framing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
