Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It says what is checked but does not state whether the tool is read-only, what it returns, whether invalid code raises errors or returns diagnostics, or any side effects. 'Validate' implies non-mutating analysis, but the gap in return and failure behavior is meaningful.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
