Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description reveals that the tool deletes code and registry entries, which is destructive. However, the name 'check_tool_health' strongly implies a read-only operation, creating a misleading impression. No additional behavioral details (e.g., side effects, required permissions) are disclosed beyond the brief destructive mention.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
