Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It confirms a write operation but says nothing about required permissions, whether the board and column must pre-exist, default field values, or what the created task includes. For a mutation tool with 4 parameters, this is a notable gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
