Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions that the symbol parameter currently returns all A-share quotes and that the original function does not exist in akshare. However, it does not disclose rate limits, data source, update frequency, or any limitations. This is insufficient for a tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
