Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish this is a non-read-only (write) but non-destructive operation, matching the 'publish... as bounties' wording. The description usefully discloses the side effect (creating bidding opportunities) and the return value, but says nothing about required permissions, idempotency, or whether already-published nodes are re-published.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
