Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It only says 'returns the tag slug' without disclosing behavior such as error handling (e.g., missing tag), case sensitivity, read-only nature, or any side effects. This is minimal transparency for a tool that will be invoked by an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
