Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose all behavioral traits. It only says 'disable' without explaining immediate effects (e.g., prevents new builds? stops running builds?), permissions required, or reversibility. This is minimal and relies on the name for understanding.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
