Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description aligns with annotations (readOnlyHint=false, idempotentHint=false, destructiveHint=false) by presenting a mutation. It adds some behavioral context, such as auto-picking a select/status column for kanban and a date/datetime column for calendar, but much of this repeats the schema's own property descriptions. It does not disclose failure modes or side effects beyond the annotations already conveying the safety profile.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
