Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. While 'List' implies a read operation, it doesn't mention any behavioral traits like pagination, sorting, default ordering, rate limits, authentication requirements, or what happens when no plans exist. For a list tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
