Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are available, so the description carries the full burden. It discloses the read-only nature ('Retrieve') and the return format ('full Markdown content'), but does not mention error behavior, edge cases, or side effects. This is minimally acceptable but lacks depth for a tool without annotation support.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
