Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavioral traits. It only says 'Create a snapshot', omitting details on whether snapshots are saved, overwritten, or affect the document. No mention of permissions, limits, or side effects. The description fails to inform the agent about the tool's behavior beyond the basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
