Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives useful context for when to use this tool: to delete a list and its ledger, while noting that people are not removed. However, it does not explicitly mention alternatives like remove_from_list for just removing a member, or reject_list_suggestion for discarding a suggestion. It implies the use case but does not explicitly route away from those alternatives. Still, it provides enough context for an agent to understand the intent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
