Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It adds the important requirement of auth env vars and implies a state transition from moderated to published. However, it does not disclose side effects (e.g., irreversibility, visibility changes, idempotency). For a simple one-parameter tool this is adequate though not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
