Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It describes what the tool analyzes ('operator conditions, versions, and dependencies') and outlines the return structure, which helps understand its read-only nature and output format. However, it lacks details on permissions needed, rate limits, or whether it performs active checks versus querying cached data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
