Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden. It discloses that the operation creates a new draft and copies settings and tasks, which implies the original is unchanged. However, it doesn't mention permissions, reversibility, error conditions, or any further side effects. It adds useful context but is minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
