Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds substantial behavioral detail beyond the annotations: anonymous works without an account, anonymous publishes return a one-time claim_token, and the page can later be claimed or updated with an lp_ key. This discloses auth needs, ownership, and downstream actions, which is exactly the kind of context that helps an agent. No contradiction with the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
