Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare the mutation profile (readOnlyHint=false, destructiveHint=false, openWorldHint=true), so the description's job is to add context beyond that. It does contribute useful flow context — the return of loop.remainingFixes and the follow-up call to verify_task — but is silent on auth, side effects of the multi-step job, or what 'loop' means.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
