Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions that the task is positioned 'within the other subtasks of that parent', hinting at ordering behavior, but lacks critical details: it doesn't specify if this is a mutating operation (implied by 'Set'), what permissions are required, potential side effects (e.g., impact on dependencies), error conditions, or response format. For a tool that modifies task relationships, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
