Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden and does well by explaining the return format ('Dict[str, str]: Pod names as keys, logs as values'), auto-detection behavior, and parameter interaction rules (e.g., 'since_seconds overrides tail_lines'). It doesn't mention rate limits, authentication needs, or destructive potential, but provides substantial operational context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
