Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. While 'Create' implies a write operation, the description fails to explain what 'compatibility tool' means (deprecated API? legacy mode?), what side effects occur, or why the parameters include timeout and connection settings unusual for node creation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
