Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must bear full burden. It discloses that the tool is paid and broadcast-quality, but fails to specify output format (e.g., JSON structure), data freshness (real-time vs. historical), or any side effects. The phrase 'the broadcast worm' hints at a common visualization but does not clarify what the tool returns.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
