Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds real value beyond annotations: output is a tri-state report, red blocks publishing, findings include evidence and fix hints, and 4.3-style findings are advisory signals for the agent to judge. However, annotations declare readOnlyHint=false, and the description never explains what side effect makes this a non-read-only operation (the 'sometimes ready patches' phrase hints at it but is not clarified).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
