Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, but the description adds substantive row-level behavior beyond them: rows with generated analysis are reset in place and regenerated, rows without analysis migrate in place when not generating. This tells the agent data can be destroyed or rewritten. It stops short of stating reversibility/rollback or permission requirements, which would be the final piece for a destructive migration.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
