Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavior. It states that strokes are removed, which signals a destructive mutation, but it does not clarify whether the operation applies recursively to descendants, whether the root node itself is included, whether it is undoable, or what other side effects may occur. The term 'scope' is underdefined.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
