Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full behavioral disclosure burden, but it only says 'draw routing.' It does not explain whether this creates a new track, modifies the board, requires an existing net, performs design-rule checks, or what side effects occur. This is effectively a behaviorally opaque description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
