Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states only that the tool generates a report with 'all metrics and statistics', but does not disclose behavioral traits such as whether it modifies data, requires authentication, or has performance implications. For a report generator, read-only nature is implied but not explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
