Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full behavioral burden. It does convey that the operation is destructive ('delete all points'), but says nothing about irreversibility, whether the envelope itself is removed or just emptied, or permission/state requirements. For a mutation tool with zero annotation coverage, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
