Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It usefully discloses the eligibility filter (infrastructure profile, 150/180 days), the two outcomes (reinforce resets counter, or allow decay), and a recommended cadence. However, it says nothing about what dry_run actually changes in behavior, nor about side effects of reinforcement beyond the counter reset.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
