Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Delete' signals a destructive/irreversible mutation, but nothing is said about persistence, permission requirements, or whether removing a card reindexes subsequent cards – all important for a mutation tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
