Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description only says 'Delete plan' without disclosing any behavioral traits such as irreversibility, authorization needs, effects on associated data, or rate limits. The description does not contradict any annotations (none present).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
