Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but discloses almost no behavioral traits. It mentions 'compatibility' without explaining the implications (e.g., deprecated features, specific version requirements), and fails to state side effects, idempotency, or what 'setting up' actually entails (e.g., creating default lights vs. configuring existing ones).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
