Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare destructiveHint=true, which for a creation tool is a notable behavioral claim the description never addresses — it says nothing about duplicate-name behavior, overwriting, permissions, or reversibility. The description adds only the location scoping, so it neither explains nor contradicts the destructive hint, leaving the agent with an unresolved ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
