Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It mentions that the tool returns a JSON string and lists the types of information included (description, platforms, version history, author, vetting status). This gives agents a good sense of what to expect, though it doesn't cover error cases or authentication requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
