Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden and does well: it discloses the payment rail (x402 on Solana or Base), the exact cost (0.025 USDC), the batch ceiling, and that output equals the full check per mint. It omits failure/partial-batch behavior and latency, which keeps it short of a 5.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
