Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description partially compensates by mentioning that the tool returns both raw and rendered HTML, which hints at the nature of the data. However, it does not disclose whether the tool requires authentication, whether it might be slow (e.g., due to rendering), or if it has any side effects (e.g., triggering hooks).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
