Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. It implies a read-only check but never explicitly states that it does not modify state, nor does it disclose any side effects, input prerequisites, or error behavior. The list of checks provides some context, but important behavioral traits are omitted.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
