Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=false and openWorldHint=false, so the safety profile is covered and the description is not contradicting it — exporting does not mutate board data. The description adds the useful constraint that the target is the *active* PCB reached 'through the extension', but it does not say where files land, whether existing outputs are overwritten (consistent with idempotentHint=false), or what happens on timeout given the 120s cap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
