Does the description explain when to use this tool, when not to, or what alternatives exist?
Usage is implied: use it to enumerate tasks, optionally scoped by industry, with a free-text query filter. It adds real guidance about ambiguous queries ('verification', 'verify') triggering clarification_required, but never says when to pick this over list_industries or search_research, nor any preconditions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
