Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With zero annotations, the description must carry full behavioral disclosure, but it is minimal. It doesn't explain side effects (e.g., whether stopping capture preserves collected data, whether clearing also stops capture, or what 'disable_cache' does). The default values for 'clear' (false) and 'disable_cache' (true) are left unexplained, reducing transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
