Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations show readOnlyHint:false, idempotentHint:false, destructiveHint:false, indicating mutation but not destruction. The description adds 'pull and ship the latest code', implying the app is updated, but does not disclose potential downtime, restart behavior, or that the operation is not idempotent. With annotations providing some baseline, a score of 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
