Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden and does disclose the transformation pipeline (script/style removal, entity decoding) and the return content (text and its length), which is more than most siblings offer. However, it omits size limits, malformed-HTML behavior, timeout/error handling, and what the signed-wallet payment requirement actually gates.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
