Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark the tool as destructive, but the description adds meaningful specifics: deletion is permanent, stored outputs are removed, and any llmContext guidance in results should be followed. This goes beyond the generic destructiveHint and gives an agent actionable behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
