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 states the tool gets block hierarchy, but doesn't explain what 'block hierarchy' entails (e.g., structure, format, depth), whether it's read-only (implied by 'Get' but not explicit), or any limitations like rate limits or authentication needs. This leaves significant gaps for a tool with no annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
